Purchase a pressure washer to remove large colonies of barnacles. [2] X Research source Allow your boat several weeks to dry, if possible, before pressure washing. -

You should be prepared, therefore, to repaint after a thorough pressure washing.

Tips
- Barnacles live and grow in salt water. Be aware you are at increased risk for barnacles if you travel or moor your boat in salt water.Thanks
- To effectively prevent against barnacle buildup, paint your boat hull with an antifouling paint. Copper oxide is toxic to barnacles and will deter them from adhering to your boat. Repaint your boat when you notice the paint job starting to flake or you see the start of barnacles adhering to your boat.Thanks
- Get rid of barnacles as soon as possible. Barnacles are living organisms, and the longer they are allowed to grow on your boat's hull, the stronger the adhesion will be.Thanks
