Ask a ski owner what they pay, and many will quote the monthly repayment. That is only one slice. The true cost of owning a personal watercraft includes a handful of recurring costs, and some arrive as lumps rather than a steady drip. Pricing them before you borrow is one of the most useful things you can do.
This article does not put dollar figures on each item, because costs vary by model, state, how often you ride and where you keep the ski. Instead, it shows you how to build your own number.
Step one: list the recurring costs
Loan repayments. Use a repayment calculator with the amount you plan to borrow, an example rate and the term. ASIC's MoneySmart has free calculators at moneysmart.gov.au. Treat the result as an estimate, since the rate you are offered and fees will change it.
Registration and licence. Check your state or territory marine authority for current fees and renewal periods.
Insurance. Get quotes. Look at the excess, what the policy covers (theft, collision, trailer, towing, liability) and what it excludes.
Fuel and oil. Consumption depends on the model and how hard you ride. Owner forums and dealers can give you a rough per-hour figure, and you can multiply it by your expected hours.
Servicing. Manufacturers publish service intervals by hours or time. A workshop can quote the cost of a standard service for your model. Skip it and small problems can become expensive ones.
Storage. At home, this might cost nothing. A paid storage yard, dry stack or marina berth is a significant ongoing cost, so ask about it before choosing a ski that needs one.
Step two: add the occasional costs
- Trailer maintenance, such as bearings, tyres and brake parts
- Batteries and spark plugs
- Impeller replacement after a bad strike
- Covers, ropes, fenders and cleaning products
- Lifejackets and other safety gear when they wear out or children outgrow them
Step three: do the per-ride maths
Add up your yearly costs, then divide by the number of times you expect to ride in a year. Be honest here. Many first-year owners ride a lot, and then life gets in the way. If you think you will ride 20 times a year, use 15 as a cautious estimate. The result is your cost per outing, and it is a useful reality check.
Where the loan fits
If you borrow to buy the ski, the repayments run whether you ride or not. A rough rule of thumb many people use is to keep total ownership costs at a share of their budget that leaves room for emergencies. There is no single right figure; it depends on your income and commitments, and a licensed professional can help you decide.
If you are thinking of financing, it helps to know your numbers before you talk to a lender. You can start a no-obligation finance enquiry once you have a budget in hand, and remember that approval is always subject to lender criteria.
Sinking funds beat nasty surprises
Many of these costs arrive once or twice a year. A simple trick is to set aside a small weekly amount into a separate account for ski costs. When rego, insurance or the annual service comes due, the money is already there. It is dull, but it takes the sting out of ownership.
Test the budget
Ask yourself what happens if:
- Your income drops for a few months
- The ski needs a major repair
- Interest rates rise (if your loan is variable)
- You want to sell and the ski is worth less than you owe
If any of those answers make you uneasy, adjust the plan: a cheaper ski, a larger deposit, a shorter term or waiting a bit longer to buy.
Keep it simple
A one-page budget with every cost on it beats a vague sense that you can afford it. Our running costs checklist is a good place to start.
