Tips & Best Practices
- Marine survey fees, slip fees, insurance, and fuel are major costs not included in the loan payment. Budget an extra 10-20% of the boat's value annually for operating costs.
- Interest on a boat loan may be tax-deductible if the boat qualifies as a second home (has sleeping, cooking, and toilet facilities).
Glossary of Terms
- Marine Survey
- A detailed inspection of the boat's condition, often required by lenders for used boats.
- Secured Loan
- The boat serves as collateral for the loan. If you default, the lender can repossess it.
