Calculate monthly repayments, total interest and annual running costs for any boat — from trailer boats to ocean cruisers. Includes a comparison of secured vs unsecured marine finance and business-use chattel mortgage options.
Boat ownership costs go well beyond the loan repayment. Here are the estimated annual out-of-pocket costs:
Estimates are indicative averages. Actual costs vary significantly by vessel size, state, and usage patterns.
Australia has one of the highest rates of recreational boat ownership in the world — with over 700,000 registered recreational vessels on the water. Financing a boat is now as accessible as financing a car, but the risks of overpaying are real. Interest costs on a $100,000 boat over 10 years at a 12% rate add up to more than $77,000 in interest alone. Getting the right rate matters enormously.
Lenders apply a "boat age loading" to used vessels. A boat over 10 years old will attract higher rates (often 1–3% above new rates) and some lenders won't finance boats over 15 years at all. For older boats, an unsecured personal loan may be the only option. For new or near-new boats from reputable dealers, the full range of marine finance products is available.
Not always. For secured marine loans, the lender registers an interest on the PPSR (Personal Property Securities Register) using the vessel's hull identification number (HIN). You do not need to have the boat registered with your state maritime authority as a condition of finance approval, though it will be required before use.
If your boat is used to generate business income, chattel mortgage is typically the potentially suitable structure. You can claim: the upfront GST credit on the BAS (for GST-registered businesses), interest deductions every year, and depreciation on the vessel and equipment. Specialist marine lenders also offer operating leases for commercial vessels, allowing accounting presentation based on the contract and applicable standards.
