Buying a boat is one thing. Owning one is another.

Beyond the purchase price, there are ongoing costs to consider – from berthing and insurance to servicing, maintenance and registration. The good news is that these costs can be planned for, and they vary enormously depending on the size and type of boat, where you keep it and how you use it.

If you’re considering buying your first boat, moving into something larger, or simply trying to work out a realistic annual budget, here’s a guide to the main costs of boat ownership in Australia.

What Are the Main Costs of Owning a Boat?

There isn’t a single figure that applies to every boat. A 30-foot sailing boat on a mooring will have a very different annual budget to a larger motor boat kept in a marina.

The main expenses generally fall into these categories:

  • Marina berth, mooring or storage
  • Insurance
  • Registration
  • Engine servicing
  • Antifouling and haul-outs
  • General maintenance and repairs
  • Cleaning and detailing
  • Fuel
  • Sails, rigging and equipment for sailing boats
  • Safety equipment
  • Upgrades and replacements

Some are predictable annual expenses, while others are better treated as a maintenance allowance for costs that arise every few years.

Marina Berths, Moorings & Storage

Where you keep your boat can be one of the biggest ongoing expenses.

For many owners, the choice will be between a marina berth and a swing mooring. Costs vary significantly depending on the boat’s length, the facilities provided and, importantly, the location.

Premium boating areas such as Sydney Harbour and Pittwater will generally command higher prices, and availability can be just as important as cost.

If you’re considering buying a boat, it’s worth investigating your berthing or mooring options early. Knowing where the boat will live, and what that will cost each year, gives you a much more realistic picture of your overall ownership budget.

Boat Insurance

Insurance is another important cost to factor into your annual budget.

The premium will depend on factors such as the boat’s value, age, type, location, how it is used and the level of cover required. Insurers may also request a current survey for some older vessels or higher-value boats.

Sydney Marine Brokerage works with Club Marine, and our team can assist buyers with organising an insurance quote and understanding the insurance requirements associated with a particular boat.

It’s a good idea to investigate insurance before settlement rather than leaving it until the day you’re due to take ownership.

Registration

Boat registration is generally a relatively small part of the overall ownership budget, but it still needs to be allowed for.

Requirements and fees vary between Australian states and territories, so check the current requirements with your relevant state maritime authority, particularly if you’re purchasing a boat interstate.

Engine Servicing

Regular engine servicing is an important part of boat ownership, even if you haven’t clocked up a large number of engine hours.

Routine servicing may include engine oil and filters, fuel filters, impellers, belts, coolant, anodes and other manufacturer-specified maintenance.

Costs will depend on the engine configuration, size and accessibility. A sailing boat with a single auxiliary diesel, for example, will generally have very different servicing requirements to a twin-engine motor boat.

Regular servicing isn’t just about avoiding breakdowns. A well-documented service history can also be a valuable asset when it eventually comes time to sell.

Antifouling & Haul-Outs

For boats kept permanently in the water, antifouling is one of the more predictable maintenance expenses.

The boat needs to be lifted from the water, the hull prepared and antifoul applied to help prevent marine growth. This is also an opportunity to inspect underwater fittings, anodes, propellers, rudders, shafts and other components.

How frequently this needs to be done will depend on the boat, where it is kept and the antifouling system being used, but it should form part of your ongoing maintenance budget.

Haul-out fees, labour and materials all contribute to the final cost, with larger boats naturally costing more.

General Maintenance & Repairs

This is the category that’s hardest to put an exact figure on.

Boats contain a lot of equipment – pumps, batteries, plumbing, electrical systems, electronics, refrigeration, steering systems, deck hardware and more. On larger or more extensively equipped boats, you may also have generators, air conditioning, watermakers, bow thrusters and other systems to maintain.

Not everything needs attention every year, but components do wear out.

Setting aside a maintenance allowance each year can make these expenses much easier to manage when they arise. Preventative maintenance is also generally preferable to waiting for something to fail.

Cleaning & Detailing

Salt, sun and weather are hard on boats.

Regular washing helps protect paintwork, gelcoat, stainless steel, clears, timber and deck fittings. Depending on the boat and how often you use it, you may choose to handle this yourself or employ a professional boat cleaner.

Periodic polishing, detailing, teak treatment and stainless-steel maintenance may also need to be factored into the budget.

Keeping on top of cosmetic maintenance doesn’t just make the boat more enjoyable to own, it can make a significant difference to its presentation and value when it comes time to sell.

Fuel

Fuel costs depend heavily on the type of boat and how you use it.

For a sailing boat that spends much of its time under sail, fuel may represent a relatively small part of the annual budget.

For a motor boat, fuel can be a much more significant variable expense. Cruising speed, engine configuration, hull design and how far you travel will all influence consumption.

When you’re considering a particular motor boat, ask about its typical cruising speed and fuel consumption. This can give you a much more useful indication of likely running costs than simply looking at engine size.

Sailing Boat Costs: Sails & Rigging

Sailing boat owners have some additional long-term expenses to consider.

Sails don’t need replacing every year, but they do have a finite lifespan. The same applies to standing and running rigging.

The lifespan of these items depends on their age, construction, usage and exposure to the elements.

When purchasing a used sailing boat, the age and condition of the sails and rigging are therefore important considerations. A boat with recently replaced standing rigging and a good sail wardrobe may represent better overall value than a cheaper boat requiring major replacements shortly after purchase.

Safety Equipment

Lifejackets, fire extinguishers, EPIRBs, flares and other safety equipment need to remain compliant and serviceable.

Some items have expiry dates, while others require periodic inspection or servicing.

These aren’t usually the largest expenses associated with owning a boat, but they should still form part of your maintenance schedule and annual budget.

Don’t Forget the Upgrades

Not every expense is essential.

Part of the enjoyment of owning a boat is making it your own. You might decide to upgrade the electronics, install solar, change the battery system, replace the tender, improve the entertainment system or invest in new sails.

These aren’t necessarily annual ownership costs, but they’re worth remembering when deciding how much of your overall boating budget you want to commit to the initial purchase.

So, How Much Should You Budget?

You’ve probably heard rules of thumb suggesting that owners should allow a certain percentage of a boat’s purchase price each year for maintenance and ownership.

These can be useful as a very rough starting point, but they don’t tell the whole story.

A better approach is to build a budget around the boat you’re actually considering:

  • Where will it be kept?
  • What will it cost to insure?
  • When are the engines next due for servicing?
  • When was it last antifouled?
  • Are there any significant maintenance items approaching?
  • How much do you expect to use it?
  • What equipment is on board that will require ongoing servicing?
  • What should you allow for unexpected repairs?

Most importantly, consider the condition of the boat you’re buying.

Two boats of the same model and age can have very different ownership costs if one has recently had its engines serviced, rigging replaced, sails upgraded and major systems renewed while the other is approaching several expensive maintenance milestones.

That’s one reason a pre-purchase survey and a good understanding of a boat’s service history are so valuable.

Look Beyond the Purchase Price

The best boat isn’t necessarily the cheapest one to buy. It’s the boat that suits how you want to use it and fits comfortably within your overall budget.

At Sydney Marine Brokerage, we deal with sailing and motor boats across a broad range of sizes and can help you understand what to look for when assessing a boat – including its equipment, maintenance history and potential ownership costs that aren’t always obvious from the asking price.

If you’re thinking about buying and aren’t sure what type of boat will suit your needs and budget, speak to our team. We can help you narrow down your options and make a more informed decision.
