How to Measure Your Boat for a Perfect-Fit Boat Cover
Buying a quality boat cover is one of the best ways to protect your investment, but choosing the right size is just as important. An incorrectly measured cover can leave your boat exposed to Australia's harsh sun, heavy rain, salt spray and strong winds.
Whether you're ordering a custom boat cover for fishing boats, ski boats, wake boats or cruisers, taking accurate measurements ensures a snug fit, longer-lasting protection and improved durability.
This guide explains exactly how to measure a boat cover so you can order the perfect custom-fit cover from Covercraft Australia.
For safe boating practices and equipment recommendations, refer to the Australian Maritime Safety Authority (AMSA), Australia's national maritime safety organisation.
Why Accurate Boat Measurements Matter
A well-fitted cover provides:
- Maximum UV protection
- Better water runoff
- Reduced wind flapping
- Longer fabric life
- Improved towing safety
- Superior protection against dust, bird droppings and tree sap
A custom cover is only as good as the measurements provided.
Choosing the correct measurements is only the first step. Understanding the differences between Custom Boat Covers vs Universal Covers will help you decide which option provides the best protection, durability and long-term value for your boat.
Step 1 – Measure the Overall Boat Length
The first measurement is your boat's overall length.
Measure from:
✔ Furthest point of the bow
to
✔ Furthest point of the transom
Do not include:
- Trailer drawbar
- Outboard motor
- Tow hitch
This measurement forms the foundation for selecting the correct cover.
Step 2 – Measure the Beam Width
The beam is the widest point of your boat.
Using a tape measure:
Measure from one outer edge to the opposite outer edge at the widest section.
Accurate beam measurements help ensure the cover wraps securely around your boat without excessive slack.
Step 3 – Measure the Height of Key Accessories
If your boat includes:
- Bimini tops
- Wake towers
- Ski poles
- Rocket launchers
- Rails
- Antennas
Record their height and note whether they remain installed during storage.
This allows Covercraft to recommend the most suitable custom cover design.
Step 4 – Identify Your Boat Type
Different boats require different cover patterns.
Examples include:
- Fishing boats
- Aluminium boats
- Bowriders
- Wake boats
- Ski boats
- Cabin cruisers
- Centre console boats
- Pontoon boats
Providing the boat's make, model and year helps achieve an even more precise fit.
Step 5 – Take Photos
Photos help verify measurements and identify accessories.
Include images of:
- Front view
- Rear view
- Side profile
- Interior
- Tower or Bimini
- Outboard area
This helps minimise measurement errors before production begins.

Common Boat Measuring Mistakes
Avoid these common errors:
❌ Measuring the trailer instead of the boat
❌ Including the outboard motor length
❌ Forgetting wake towers or Bimini tops
❌ Guessing dimensions
❌ Using old manufacturer specifications instead of measuring the actual boat
Why Choose a Custom Boat Cover?
Unlike universal covers, a custom-made cover is designed specifically for your boat.
Benefits include:
- Better fit
- Superior weather protection
- Longer lifespan
- Reduced fabric movement
- Improved appearance
- Easier installation
- Greater value over time
Once you've invested in a perfectly fitted cover, following a regular Boat Cover Maintenance Guide for Maximum Lifespan will help keep the fabric, stitching and waterproof coatings performing for years.
