## Tools (4)

- `calculate_boat_loan`: Runs the yacht.loans boat loan calculator on your numbers: monthly loan payment, payment with insurance, amount financed, balloon left at the end when payments are figured over more years than the term, interest over the term, sales tax (from a state rule on the site or your own rate and cap), cash at closing, and the loan balance at the end of each year.
- `estimate_uscg_documentation_fees`: Adds up the Coast Guard NVDC fees (46 CFR 67.550) to document a financed recreational boat: Abstract of Title, initial certificate or exchange into your name for 1 to 5 years, bill of sale and preferred mortgage recording by page count, and a certified copy for the lender, plus the full NVDC fee table.
- `get_boat_sales_tax`: The boat sales or use tax rule yacht.loans has confirmed for a state from its statute or tax agency: rate, cap, exemptions or special tests (such as California's 12-month test or Florida's $18,000 cap), the citation, source URL and the date it was read. Omit state to list every state covered.
- `list_boat_lender_terms`: What banks, credit unions, marine lenders and brokers publish on their own boat loan pages, as read by yacht.loans: rate ranges with their dates, loan amounts, longest terms, down payment and boat age or size rules, with each lender's URL. Filter by lender type or name; not offers and not a ranking.
