South Carolina offers a full spectrum of boating, from the Lowcountry tidal creeks around Charleston and Beaufort to the deep inland reservoirs of Lake Murray, Lake Hartwell, Lake Keowee, and Lake Marion. The SC coast is steeped in maritime tradition, while the Savannah River and Saluda River systems feed world-class inland fisheries.
The single biggest financial story in SC boating is the $500 sales tax cap. South Carolina charges 5% sales tax (technically the Infrastructure Maintenance Fee on boats) but caps the total at $500 per boat, regardless of purchase price. On a $100,000 boat, that is $500 in tax instead of $5,000, and on a $500,000 yacht the savings exceed $24,000. This makes SC one of the most tax-advantaged states in the country to buy a boat.
Boat loan rates in South Carolina typically range from 6.24% to 11.49% APR depending on lender, credit score, and loan amount. Credit unions like SC Federal Credit Union, Founders FCU, and Carolina Foothills FCU frequently beat national marine specialists on mid-size loans.
Your credit score is the biggest factor in the rate you'll receive. Here's what to expect from lenders in 2026.
| Credit Score | Rating | Typical APR (New) | Typical APR (Used) | Approval Odds |
|---|---|---|---|---|
| 750 - 850 | Excellent | 5.49% - 6.99% | 6.49% - 7.99% | Very High |
| 700 - 749 | Good | 6.49% - 8.49% | 7.49% - 9.49% | High |
| 660 - 699 | Fair | 8.49% - 11.99% | 9.49% - 12.99% | Moderate |
| 620 - 659 | Below Avg | 11.99% - 15.99% | 12.99% - 17.99% | Limited |
| Below 620 | Poor | 15.99% - 21%+ | Difficult to qualify | Low - consider co-signer |
Rates are indicative ranges based on current market data. Your actual rate depends on lender, loan amount, term, and full credit profile. Always verify directly with lenders.
Example: $50,000 boat, $10,000 down, 7-year term
The difference between excellent and below-average credit: $171/month or $14,364 over the life of the loan
South Carolina's $500 cap on boat sales tax is one of the strongest buyer incentives in the US. Savings versus uncapped states are dramatic on larger boats.
| Boat Price | Tax Without Cap (5%) | SC Tax (Capped) | You Pay | Savings |
|---|---|---|---|---|
| $10,000 | $500 | $500 | $500 | $0 (at cap) |
| $25,000 | $1,250 | Capped | $500 | $750 |
| $50,000 | $2,500 | Capped | $500 | $2,000 |
| $100,000 | $5,000 | Capped | $500 | $4,500 |
| $250,000 | $12,500 | Capped | $500 | $12,000 |
| $500,000 | $25,000 | Capped | $500 | $24,500 |
The $500 cap applies to both new and used boats purchased in SC or brought into SC. It is one of the strongest buyer incentives in the country, especially for boats over $25,000.

Your monthly loan payment is only part of the picture. Budget for these ongoing costs.
Based on boat price, down payment, rate, and term. Use calculator above.
/year. Required by most lenders. Premiums vary with boat value, usage, and location.
/month for wet slip. Dry storage $80-$500/mo. Trailer at home = free.
/trip depending on engine size and distance. Sailboats much less.
/year. Rule of thumb: 10% of boat value annually. Saltwater = more.
/season. Haul-out, shrink-wrap, antifreeze. Cost varies by climate.
Rule of Thumb
Budget 1.5x your monthly loan payment for total cost of ownership. A $600/mo boat payment means approximately $900/mo all-in when you include insurance, fuel, maintenance, and storage.

A step-by-step guide to the boat financing process, from pre-approval to closing.
Pull your free credit report from annualcreditreport.com. Know where you stand before you apply. Scores above 700 get the best rates. If below 660, consider improving your score first or finding a co-signer.
Use the calculator above to estimate payments. Remember: budget 1.5x your loan payment for total monthly cost (insurance, fuel, storage, maintenance). Don't forget sales tax and registration fees.
Apply for pre-approval with at least 2-3 lenders to compare rates. Multiple credit inquiries within 14-45 days count as a single inquiry. Have ready: ID, SSN, proof of income, 2 years tax returns, bank statements.
Shop with your pre-approval amount in mind. For used boats, get a marine survey before committing. Check NADA Guides for fair market value. Inspect the hull, engine hours, and maintenance records.
Submit the purchase agreement to your lender. They'll order a title search and may require a marine survey for used boats. Provide proof of insurance. Closing typically takes 3-7 business days.
The lender files the title with their lien noted. Register the boat with your state's boating agency through the local tax collector or DMV. Set up insurance before taking delivery.

| Warranty | Manufacturer warranty included | Usually no warranty |
| Marine Survey | Usually not required | Often required by lender |

| Dealer Promos | Often available (0% or low APR) | Rare |
Expert tips for South Carolina boat buyers.
On anything over $10,000, SC saves you money versus uncapped states. On a $100,000 boat, you save $4,500 versus a 5% uncapped state. On a $500,000 boat, the savings exceed $24,000. Use this in cross-state shopping.
SC counties assess annual personal property tax on boats. Boats are assessed at 10.5% of market value, then county millage applies. On a $50K boat, expect $500-$1,500 per year depending on county.
SC Federal and Founders FCU regularly beat national marine specialists on loans under $100K. Get a pre-approval before walking into a dealer.
Boats kept in Charleston, Beaufort, Georgetown, or Horry counties face hurricane-driven insurance premiums. 30%-50% higher than inland boats of the same type.
Lake Murray, Lake Keowee, and Charleston-area marinas have waiting lists. Confirm slip, dry stack, or trailer plan before you commit.
Saltwater and hurricane history are real risks on Lowcountry boats. A $400-$700 survey catches issues before financing. Required by most lenders on boats over 10 years old.
Your county of residence drives the annual property tax bill. If you have flexibility on domicile, lower-millage counties save real money year after year.
The $500 cap makes SC extremely attractive for higher-value boats. Work with dealers familiar with the cap application to make sure it is filed correctly at titling.
