Learning how to clean a boat hull will help you preserve the value of your vessel and restore its performance.

Hopefully you spent considerable time out on your boat this Christmas and school holidays, this also means that it might be time to give some love back to your vessel.

Cleaning a Boat Hull

Boat hulls are constantly exposed to the elements. Consequently, they sustain heavy abuse. This is especially true if you travel in polluted water, though regular trips in salt or fresh water can also lead to hull corrosion and barnacle growth. By maintaining a clean boat hull you will help preserve the integrity of your entire vessel. In addition, keeping your hull shiny and smooth will help you move through water at a faster rate.

Experts recommend cleaning your hull several times a year depending on how often you use your boat. For permanently moored boats, one option is to hire a professional boat hull cleaner. Pros use special scuba gear to dive under the water and thoroughly clean parts of the hull that are difficult to reach. Professional hull cleaners can get your boat looking shipshape again, but they don’t come cheap.

How to Clean a Boat Hull

You can do it yourself by following these simple steps:

Basic Cleaning

Use a low power hose or bucket of fresh water to rinse the hull as thoroughly as possible. You want to get rid of the salt build-up and loosen any algae or mould that may be attached to your boat hull.

Choose a cleaner specialised for the use of boat hulls and mix it with water as directed on the product’s label.

Use a large, soft sponge and dip it into the cleaning solution. Wring out the sponge slightly, then wash each section of the boat hull. Take care not to damage the hull’s paint job. Use gentle strokes in a circular pattern. You can also employ a bow-to-stern motion if you are using a heavy-duty cleaner.

Once you have finished scrubbing the hull, rinse it with fresh water.

The final step requires a second sponge soaked with clean water. Use this sponge to wipe off any residual cleaning solution and watermarks.

Extensive Cleaning

For really tough jobs it’s best to use muriatic acid (or another acid-based cleaner) and a strong hose to clean your boat hull.

  • Use the hose to thoroughly rinse your boat hull, making sure to remove any barnacles, weeds or other slime.
  • Use a soft bristle brush to remove excess cleaner and grime.
  • Repeat the cleaning process on the opposite side of your boat.
  • Rinse the entire hull thoroughly, making sure to eliminate all residual acid from the hull and trailer as it can sometimes cause rust spots and corrode.
