This guide provides technical requirements for 2026 licensing procedures. South Carolina mariners must navigate both United States Coast Guard regulations and state-level commercial permits to operate legally.
Understanding eligibility criteria, sea service documentation, and renewal procedures prevents application delays. Charleston and Myrtle Beach maritime operations demand properly credentialed captains who maintain current federal and state authorizations.
Federal USCG Captain’s License Types
The United States Coast Guard issues Merchant Mariner Credentials authorizing commercial vessel operations. Two primary credential categories serve different operational capacities and passenger limits.
OUPV Six-Pack License
The Operator of Uninspected Passenger Vessels credential authorizes transporting up to six paying passengers. This license serves charter fishing guides, small tour operators, and water taxi services operating throughout South Carolina coastal waters.
OUPV operational scope:
- Maximum six passengers for hire
- Uninspected passenger vessels under 100 gross registered tons
- Near coastal routes up to 100 miles offshore
- Inland waters including rivers, lakes, and protected bays
- Great Lakes operations with appropriate endorsement
Master 25, 50, and 100 Ton Credentials
Master credentials authorize unlimited passenger operations on inspected vessels. Tonnage rating determines maximum vessel size under your command authority.
Master 25-ton licenses accommodate smaller commercial tour vessels operating in Charleston Harbor and Myrtle Beach waters. Master 50-ton and 100-ton ratings expand employment opportunities to larger ferry operations and offshore charter vessels.
Master 25 Ton License
- Vessels up to 25 gross tons
- Unlimited passenger capacity
- Inspected vessel operations
- Entry-level Master credential
- Coastal and inland endorsements available
Master 50/100 Ton License
- Vessels up to 50 or 100 gross tons
- No passenger restrictions
- Extended operational zones

- Expanded career opportunities
Basic Eligibility Requirements
Coast Guard regulations mandate specific prerequisites for credential issuance. Meeting these requirements before application submission prevents processing delays and rejection.
| Requirement Category | OUPV License | Master License |
| Minimum Age | 18 years old | 19 years old |
| Total Sea Service | 360 documented days | 360 documented days |
| Recency Rule | 90 days within past 7 years | 90 days within past 7 years |
| Citizenship | U.S. Citizen or Permanent Resident | U.S. Citizen or Permanent Resident |
| TWIC Card | Mandatory | Mandatory |
| Drug Test | DOT-compliant screening required | DOT-compliant screening required |
| Medical Exam | CG-719K form required | CG-719K form required |
| First Aid/CPR | Current certification required | Current certification required |
Sea Service Documentation Standards
Sea service represents documented time operating vessels on navigable waters. Applicants must accumulate 360 total days with 90 days occurring within the seven years immediately preceding application submission.
Document your experience using Coast Guard form CG-719S. Each entry demands vessel identification, operational dates, waters navigated, and verification signatures from vessel owners or currently licensed operators.
Days accumulate cumulatively throughout your boating experience. A four-hour fishing trip counts as one service day. Multi-day offshore passages count each calendar date separately in your total calculation.
Sea Service Calculation: Any time spent on a vessel in operation counts toward your 360-day requirement. Recreational boating, commercial fishing crew experience, and volunteer maritime activities all qualify when properly documented and verified on CG-719S forms.
Transportation Worker Identification Credential
The TWIC provides maritime security clearance through Transportation Security Administration processing. Apply for your TWIC card before beginning your licensing course to prevent delays in your application timeline.
TWIC credentials cost approximately $125 with five-year validity periods. Processing demands fingerprinting and background verification completed at approved TSA enrollment centers throughout South Carolina.
Medical Certification Process
Coast Guard form CG-719K documents your physical examination conducted by a licensed physician, physician assistant, or nurse practitioner. The examination must occur within twelve months before application submission to the Regional Exam Center.
Vision requirements specify 20/40 acuity in each eye, correctable to 20/20 with lenses. Color vision testing verifies ability to distinguish red, green, and blue navigation lights. Hearing standards require understanding conversational voice at five feet distance.
Certain medical conditions demand additional documentation from specialists. Cardiovascular conditions, diabetes requiring medication, and neurological disorders need supplemental evaluation reports attached to your CG-719K form.
Drug Testing Requirements
DOT-compliant drug screening tests for marijuana, cocaine, amphetamines, opiates, and phencyclidine. Testing must occur within six months of application submission using approved collection facilities and laboratories.
Results must be submitted on Coast Guard form CG-719P. Alternatively, provide documentation of enrollment in a random drug testing program meeting Department of Transportation and Coast Guard standards for commercial maritime operations.

License Upgrades and Career Advancement
Initial captain credentials provide pathways toward advanced ratings and specialized operational endorsements. Understanding upgrade requirements enables South Carolina mariners to plan systematic career progression in commercial maritime sectors.
OUPV to Master License Upgrade
Advancing from OUPV to Master credential requires documented commercial sea service plus completion of a USCG-approved upgrade course. The upgrade eliminates the six-passenger restriction and permits operations on inspected passenger vessels.
The Coast Guard mandates 360 days of documented commercial experience operating as a licensed OUPV captain. Your sea service must demonstrate passenger-carrying operations conducted under your OUPV credential authority.
Upgrade courses typically span four to seven days of intensive instruction. Course material covers vessel stability calculations, advanced piloting techniques, and regulatory compliance topics beyond OUPV examination scope.
Upgrade Timeline: Most South Carolina charter captains complete the OUPV to Master upgrade within two to three years after obtaining initial credentials. The expanded passenger capacity significantly increases seasonal revenue potential in the Charleston and Myrtle Beach tourism markets.
Tonnage Rating Increases
Advancing your tonnage rating from 25 to 50 tons or 50 to 100 tons demands verified sea service on progressively larger commercial vessels. No additional written examination applies for tonnage increases within the Master credential category.
Each tonnage advancement requires 360 documented days operating vessels within your current license rating. Minimum 90 days must occur on vessels approaching your target tonnage threshold to demonstrate relevant experience.
| Current License Rating | Target License Rating | Sea Service Days Required | Minimum Vessel Experience |
| Master 25 Ton | Master 50 Ton | 360 days on vessels to 25 tons | 90 days on vessels 20-25 tons |
| Master 50 Ton | Master 100 Ton | 360 days on vessels to 50 tons | 90 days on vessels 45-50 tons |
Sailing Endorsement
Sailing endorsements authorize commanding sailing vessels under both wind and engine power. This credential benefits yacht delivery operations, sailing charter businesses, and sail training programs operating from South Carolina marinas.
Obtaining a sailing endorsement demands 360 documented days operating sailing vessels. Coast Guard regulations define qualifying vessels as those with auxiliary engines where wind power provides the primary means of propulsion.
No separate written examination exists for sailing endorsements. Submit properly documented sailing experience recorded on form CG-719S with your credential application to the appropriate Regional Exam Center.

The Renewal Process
Coast Guard captain credentials expire after five years from issuance date. The renewal process maintains credential validity without repeating original examination requirements when specific conditions are met.
Two Renewal Pathways
The Coast Guard provides two distinct pathways for credential renewal. Select the appropriate method based on your documented operational activity during the preceding five-year credential validity period.
Path A: Sea Service Documentation Method
Document 360 days of sea service occurring within the five years preceding your credential expiration date. This method suits actively employed captains maintaining regular commercial vessel operations.
Experience must be recorded on Coast Guard form CG-719S with complete vessel identification details and proper verification signatures. Each entry demands accurate operational dates and comprehensive information.
The 360-day total combines various licensed operations conducted under your current credential authority. Part-time charter operations, seasonal tour services, and vessel delivery work all contribute toward your required sea service total.
Path B: Course or Take-Home Examination Method
Complete a Coast Guard approved renewal course if insufficient sea service exists during your credential validity period. This option serves inactive licenses or captains with limited recent operational time in commercial vessel operations.
Renewal courses typically span one to three days of classroom instruction. Course material reviews navigation rules, safety procedures, and regulatory updates implemented during the past five years since your original examination.
Alternatively, request an open-book take-home examination from your Regional Exam Center. This written test covers identical material as renewal courses and can be completed at your own pace within one year of expiration.
Renewal Deadline Warning: Operating any vessel for hire on an expired captain license violates federal law regardless of grace period status. The one-year grace period preserves your renewal eligibility but does not authorize continued commercial operations after expiration.
Required Renewal Documentation
Complete documentation prevents processing delays and application rejections. Assemble all required forms before submitting your renewal package to the Regional Exam Center serving South Carolina waters.
CG-719B Master Application Form
The Master Application serves as your primary renewal document. Mark the “Officer Renewal” checkbox clearly in the application type section of the form.
Complete every section with current accurate information. Include your existing license number, updated personal details, and the specific credential being renewed. Sign and date the application before submission to the REC.
CG-719K Physical Examination Form
Current medical certification from a licensed physician, physician assistant, or nurse practitioner is mandatory for renewal. The physical examination must occur within twelve months immediately preceding your renewal application submission date.
Coast Guard form CG-719K specifies exact examination requirements and standards. Vision acuity, hearing function, cardiovascular condition, and general physical health receive comprehensive assessment during the examination.
Certain medical conditions demand additional specialist documentation or evaluations. Discuss any health concerns with your examining healthcare provider during the appointment to ensure proper documentation.
CG-719P Drug Testing Documentation Form
Provide proof of enrollment in a DOT-compliant random drug testing program or complete a pre-employment drug screening. Testing must occur within six months preceding application submission to the Regional Exam Center.
Random testing programs require employer or consortium documentation verifying enrollment. The program must meet Department of Transportation and Coast Guard standards established for commercial maritime workers.
CG-719S Sea Service Documentation Form
Document your 360 service days on Coast Guard form CG-719S when using Path A renewal method. Each vessel demands a separate entry with comprehensive operational details and proper verification.
Essential information required includes:
- Vessel name and official Coast Guard documentation number
- Gross tonnage and propulsion system type
- Operational routes and specific waters navigated
- Service dates and cumulative days aboard vessel
- Position held and specific duties performed aboard
- Verification signature from vessel owner or currently licensed captain
Application Submission Procedures
Pay all renewal fees through the Pay.gov system before submitting application materials to the Regional Exam Center. The Coast Guard no longer accepts payment checks accompanying mailed applications.
Compile all required documentation into one complete PDF file. Email your assembled package to the appropriate Regional Exam Center. South Carolina mariners submit applications to the Charleston REC office serving the southeastern region.
Processing requires approximately four to ten weeks typically depending on application volume. The Coast Guard issues an email receipt confirming application acceptance. Your renewed credential arrives by postal mail following final approval.
| Renewal Step | Timeline Before Expiration | Action Required |
| Begin Planning | 120 days | Review sea service documentation or schedule renewal course |
| Complete Medical Exam | 90 days | Schedule and complete CG-719K physical examination |
| Drug Testing | 90 days | Complete DOT drug screening or verify random program enrollment |
| Pay Fees | 60 days | Submit payment through Pay.gov system |
| Submit Application | 60 days | Email complete PDF package to Regional Exam Center |
| Follow Up | 30 days | Verify receipt and respond to any REC requests |
The One-Year Grace Period
Coast Guard regulations provide a one-year grace period following credential expiration. During this twelve-month window, you maintain eligibility to renew through standard procedures without retaking your original full course and examination.
The grace period does not authorize continued commercial operations. Operating any vessel for hire on an expired license violates federal regulations regardless of grace period status. All commercial activities must cease upon expiration.
After one year passes beyond expiration, you lose standard renewal eligibility. Restoring your credential requires completing a new original captain license course and passing all examinations as a first-time applicant.
Grace Period Clarification: The one-year grace period exists solely for administrative convenience in processing renewals. It does not extend your legal authority to operate commercially. Plan renewal procedures to maintain continuous valid credential status throughout your commercial maritime career.
South Carolina Specific Requirements- Captain’s License in South Carolina
Commercial vessel operations in South Carolina demand coordination between federal Coast Guard credentials and state-issued permits. Understanding both regulatory systems ensures complete legal compliance for commercial maritime activities.
State Boating Safety Education
South Carolina does not require a separate NASBLA boating safety certificate for federally licensed captains. Your Coast Guard captain license fulfills South Carolina’s boating education requirements for commercial operators.
Recreational boaters born after July 1, 2007, must complete a NASBLA-approved boating safety course to operate vessels in South Carolina waters. This state requirement does not apply to holders of valid federal captain credentials.
Commercial Fishing Guide License
South Carolina requires a distinct Saltwater Fishing Guide License for anyone providing guided fishing services for compensation in state waters. Your Coast Guard captain license does not substitute for this mandatory state permit.
The South Carolina Department of Natural Resources issues saltwater fishing guide licenses. Requirements include:
- Valid South Carolina business license registration
- Completed guide license application with state fees
- Current South Carolina saltwater fishing license
- Proof of commercial liability insurance coverage
- Annual license fee payment to DNR
- Compliance with state catch reporting requirements
Saltwater fishing guide licenses expire December 31 each calendar year. Renewal demands submitting catch reports and paying annual fees before conducting any guided fishing operations.
Charter Vessel Permits
Vessels conducting charter fishing operations in South Carolina waters need proper state registration through the Department of Natural Resources. This permit authorizes the vessel for commercial passenger operations under state jurisdiction.
Charter vessel permits cost approximately $50 annually for vessels operating in state waters. Apply through South Carolina DNR with vessel documentation, insurance verification, and captain credential copies.
Additional South Carolina Commercial Permits
Specific commercial maritime operations may demand additional state-level permits beyond basic federal captain credentials:
| Operation Type | Required State Permit | Issuing Agency | Annual Fee |
| Saltwater Fishing Guide | Fishing Guide License | SC Department of Natural Resources | $200 |
| Charter Fishing Vessel | Charter Vessel Permit | SC Department of Natural Resources | $50 |
| Commercial Water Taxi | Business License | SC Department of Revenue | Varies by county |
| Wildlife Viewing Tours | Commercial Use Authorization | SC State Parks | $100 |
| Dolphin Watching Tours | Marine Mammal Viewing Permit | NOAA Fisheries | No fee, federal authorization required |
What You Can Do: USCG License vs. Complete Permitting
Understanding distinctions between Coast Guard credentials and South Carolina state requirements clarifies your complete legal operating authority across different commercial activities in state and federal waters.
Coast Guard License Alone
Federal captain credentials authorize:
- Passenger vessel operations for hire in federal waters
- Transporting passengers beyond state jurisdiction
- Water taxi and harbor shuttle services without fishing
- Sightseeing tours not involving state-regulated activities
- Vessel delivery and repositioning services
- Non-fishing charter operations in federal waters
Coast Guard License Plus State Permits
Combined federal and state licensing permits:
- Saltwater fishing charter operations in state waters
- Guided hunting and fishing excursions
- Combination sightseeing and fishing trips
- Complete charter business operations anywhere
- Activities in state-managed marine areas
- Wildlife viewing in protected state waters
Intracoastal Waterway Operations
The Atlantic Intracoastal Waterway traversing South Carolina falls under federal jurisdiction for most commercial operations. Your USCG captain license with inland waters endorsement authorizes commercial passenger operations throughout the Intracoastal Waterway without additional state permits.
However, charter fishing activities in the Intracoastal Waterway still require South Carolina fishing guide licenses when operating within state waters. The waterway’s federal status does not exempt fishing-related activities from state permitting requirements.
Compliance Best Practices
Maintain copies of all licenses and permits aboard your vessel during all commercial operations. South Carolina DNR officers and Coast Guard boarding teams may request documentation verification during routine safety inspections.
Track renewal dates separately for federal credentials and state permits. Create calendar reminders minimum 90 days before each expiration date to initiate renewal procedures and prevent operational authority lapses.
Keep current insurance certificates matching your license requirements and passenger capacity. Most South Carolina marinas and charter booking platforms verify insurance coverage before allowing commercial vessel operations from their facilities.

Near Coastal vs. Inland Waters Endorsements
Coast Guard credentials specify operational zones through route endorsements. Understanding near coastal versus inland waters endorsements determines where you can legally operate commercial vessels throughout South Carolina.
Inland Waters Endorsement
Inland credentials authorize operations on rivers, lakes, sounds, and protected bays where vessels maintain proximity to shorelines. The Intracoastal Waterway, Charleston Harbor, and all South Carolina rivers fall under inland waters classification.
Inland endorsements suit captains operating water taxis, harbor tours, and river excursions. The examination covers navigation rules specific to restricted waters and piloting techniques for confined channels.
Near Coastal Endorsement
Near coastal licenses permit operations extending 100 nautical miles offshore from designated boundary lines. This endorsement enables access to offshore fishing grounds and coastal routes between South Carolina ports.
Most South Carolina charter captains obtain near coastal endorsements for offshore fishing operations. The examination includes additional navigation plotting, weather interpretation, and offshore emergency procedures beyond inland waters scope.
Great Lakes Endorsement
Great Lakes endorsements authorize operations on the five Great Lakes and their connecting waterways. This endorsement holds limited relevance for South Carolina-based captains unless planning vessel delivery or relocation operations to northern waters.
Great Lakes endorsements can be added to existing credentials through documented sea service on the lakes. No separate examination is required when adding to a near coastal or inland endorsed credential.
Inland Waters Coverage
- All South Carolina rivers and tributaries
- Charleston Harbor and Winyah Bay
- Atlantic Intracoastal Waterway
- Protected sounds and estuaries
- Lakes and reservoirs throughout state
Near Coastal Coverage
- All inland waters included
- Atlantic Ocean to 100 miles offshore
- Offshore fishing grounds and reefs
- Coastal transit between ports
- Gulf Stream access for pelagic fishing
Selecting Appropriate Endorsements
Choose endorsements based on your intended commercial operations in South Carolina waters. Harbor tour operators may need only inland endorsements, while offshore charter fishing captains require near coastal authority.
Many candidates obtain both inland and near coastal endorsements simultaneously during initial licensing. The examination covers both operational zones with minimal additional study time required for dual endorsements.
Your sea service documentation must include operations in each endorsed zone. Documented experience on inland waters alone does not qualify for near coastal endorsements without supplemental offshore sea service.
Course Completion and Examination
Coast Guard approved courses prepare candidates for written examinations administered at Regional Exam Centers. Understanding course options and examination procedures optimizes your preparation timeline and first-attempt pass rate.
USCG Approved Course Options
The Coast Guard requires completion of an approved course before sitting for captain license examinations. Two primary course formats accommodate different learning styles and scheduling needs.
Classroom Instruction Format
In-person classroom courses typically span one to two weeks of daily instruction. This format provides direct interaction with instructors, hands-on chart work, and immediate question resolution during the learning process.
Classroom instruction suits candidates who prefer structured learning environments and benefit from group discussion. The condensed timeline enables rapid course completion for candidates with available time blocks.
Online Learning Format
Online courses provide self-paced study completed over two to six months depending on individual time commitment. This format accommodates working professionals and candidates with scheduling constraints.
Online instruction includes video lessons, interactive chart plotting exercises, and practice examinations. Students progress through modules independently with instructor support available via email and phone consultation.
Course Content and Knowledge Areas
USCG approved courses cover all examination subject areas mandated by federal regulations. Course completion certificates verify you received required instruction before testing at the Regional Exam Center.
Primary knowledge areas include:
- Navigation rules and right-of-way regulations
- Chart navigation and position plotting techniques
- Magnetic compass deviation and variation
- Tides, currents, and piloting calculations
- Weather systems and maritime meteorology
- Safety equipment and emergency procedures
- Federal regulations and vessel documentation
- Vessel stability and loading principles
Examination Procedures at Regional Exam Centers
Written examinations are administered at Coast Guard Regional Exam Centers following course completion. Schedule your examination appointment after receiving your course completion certificate to ensure qualification.
South Carolina candidates typically test at the Charleston REC office. The examination consists of multiple-choice questions covering all course content areas with passing scores determined by credential type sought.
OUPV examinations require passing scores on navigation rules, deck general, and navigation plotting modules. Master credential examinations add deck safety and navigation problems modules with higher passing thresholds.
Bring approved chart navigation tools including parallel rulers, dividers, and pencils to your examination appointment. The REC provides practice charts and plotting sheets for navigation problems during testing.
Examination Retake Procedures
Candidates who do not pass all examination modules on first attempt may retake failed sections. The Coast Guard permits three examination attempts within one year of course completion before requiring course retake.
Study weak areas identified through examination results before scheduling retake appointments. Many candidates benefit from additional chart work practice and navigation rules review between testing attempts.
First-Attempt Pass Rates: Quality USCG-approved courses achieve 85-95% first-attempt pass rates through comprehensive instruction and examination preparation. Adequate study time and practice chart work significantly increase your probability of passing all modules on first attempt.
Application Submission After Passing Examinations
Following successful examination completion, submit your complete application package to the Regional Exam Center. The REC processes your application and issues your Merchant Mariner Credential upon verification of all requirements.
Processing time ranges from four to eight weeks depending on application volume and completeness. Your credential arrives by postal mail to the address listed on your CG-719B application form.
The issued credential specifies your license type, tonnage rating, route endorsements, and any special endorsements obtained. Verify all information for accuracy immediately upon receipt and report any errors to the REC within 30 days.

Frequently Asked Questions
How long does getting a captain license in South Carolina take?
The complete timeline ranges from two to six months from initial course enrollment to receiving your Merchant Mariner Credential. Classroom courses compress learning into one to two weeks plus eight to twelve weeks for Coast Guard processing. Online courses extend learning over two to four months plus processing time. Starting TWIC application, medical examination, and documentation gathering early accelerates your overall timeline significantly.
Can I operate in other states with my Coast Guard license?
Yes, Coast Guard captain credentials provide nationwide authority across all United States territorial waters including federal and state jurisdictions. Your federal license authorizes passenger vessel operations anywhere within U.S. waters. However, individual states impose additional permits for specific activities like fishing guides or operations in state-controlled waters. Each state maintains different supplemental requirements beyond your federal captain credential.
What happens when my captain license expires?
Operating any commercial vessel on an expired captain license violates federal law regardless of circumstances. The Coast Guard provides a one-year grace period for renewal purposes only. During this twelve-month window following expiration, you can renew through standard procedures without retaking your original course. After one year passes beyond expiration, you must complete a new original license course and pass all examinations to restore your credential. Plan renewals to maintain continuous valid status.
Do I need sea service for my first captain license?
Yes, the Coast Guard mandates 360 days of documented sea service before issuing any captain credential. This experience must include minimum 90 days within the seven years immediately preceding your application under current recency requirements. Sea service can derive from recreational boating, commercial fishing crew work, or any vessel operation time. Proper documentation on form CG-719S with verification signatures from vessel owners or licensed captains is mandatory for all service claimed.
What distinguishes inland from near coastal licenses?
Inland credentials authorize operations on rivers, lakes, sounds, and protected bays where vessels maintain proximity to shorelines. The Intracoastal Waterway and Charleston Harbor fall under inland classification. Near coastal licenses permit operations extending 100 nautical miles offshore into ocean waters. The examination includes additional offshore navigation, weather interpretation, and emergency procedures for near coastal credentials. Most South Carolina charter captains obtain near coastal endorsements for offshore fishing access.
What does getting a captain license in South Carolina cost?
Total first-time expenses range from $1,525 to $2,450 for OUPV credentials including all required components. This includes course tuition ($800-$1,500), Coast Guard application fee ($140), TWIC card ($125), physical examination ($75-$150), drug screening ($45-$95), first aid certification ($75-$125), and miscellaneous expenses. Master credentials cost $1,725 to $2,750 total. South Carolina-specific permits add $200-$300 annually for charter fishing operations requiring state fishing guide licenses.
Does South Carolina require a separate boating license for captains?
No, South Carolina does not require a separate NASBLA boating safety certificate for federally licensed captains. Your Coast Guard captain license fulfills all South Carolina boating education requirements. However, commercial fishing guide operations require a separate Saltwater Fishing Guide License from the South Carolina Department of Natural Resources regardless of your federal captain credential. This state permit costs $200 annually and mandates business license registration.
Can I renew my captain license without 360 days of sea service?
Yes, the Coast Guard provides Path B renewal when insufficient sea service exists during your five-year credential validity period. Complete a USCG-approved renewal course or request an open-book take-home examination from your Regional Exam Center. Both options cover navigation rules, safety procedures, and regulatory updates without requiring documented sea service. This pathway accommodates inactive licenses or captains with limited recent commercial operations while maintaining credential validity.
What is the TWIC card and why is it required?
The Transportation Worker Identification Credential provides maritime security clearance through Transportation Security Administration background verification. The TWIC card is mandatory for all Merchant Mariner Credentials including captain licenses. Apply at approved TSA enrollment centers with fingerprinting and identity verification. The process costs approximately $125 with five-year validity. TWIC processing takes four to six weeks, so apply immediately upon course enrollment to prevent application delays when submitting your complete captain license package.
