Boat Blisters: What Causes Them and How to Prevent Them

Boats are meant for water, but excess moisture can cause a lot of problems for your watercraft. From rust to blistering, leaving your boat in the water constantly can be the source of many cosmetic blemishes, some of which can pose a significant threat to your boat's integrity. Different parts of a boat can experience different issues from excess water – metal on the boat will corrode while the gel coat will develop boat blisters. Let’s dive in and look at what causes this blistering and how to prevent it.

The Cause Of Boat Blisters

A primary cause of hull blisters is the long-term immersion of the hull in water. Water in warmer climates seems to cause these boat blisters to develop more often.

Most boats have areas that are porous, like the fiberglass and resin structure. When porous areas are exposed to water for excessive periods of time, osmotic pressure moves in and causes blistering.

Stress cracks on the hull below the waterline can result in the formation of hull blisters.

How To Prevent Boat Blisters

Before purchasing your boat, check to see which type of resin the builder has used. Certain resins may help to deter boat blisters better than others.

Apply a barrier coat. An epoxy, or similar material that seals out the moisture, is usually better than a polyester gel coat.

Reduce the amount of time that your boat stays in the water. Take the time to look into different types of boat lifts for sale that will keep your boat above water.

Use of a trailer, boat lift or proper jet ski storage will reduce the likelihood of boat blisters forming on the hull of your watercraft.
