Fix the Real Problem Behind Boat Hull Blisters—It’s Not the Water
Say Goodbye to Hull Damage: The Gatorbak Solution
Boat hull blisters—also known as osmotic blisters—are one of the most frustrating and expensive issues boat owners face. These bubbles form under the gelcoat when water seeps into the fiberglass layer, causing pressure and damage over time. And one of the most common but overlooked causes? Your carpeted trailer bunks.
How Trailer Bunks Cause Hull Blisters
Most trailer bunks are covered in carpet, which seems harmless—until you realize it's working like a sponge. Here's why carpeted bunks can lead to hull damage:
- They retain water – Carpet soaks up and traps moisture for hours or even days.
- No airflow – The carpet stays pressed against your hull, not allowing it to breathe or dry properly.
- Trapped debris and chemicals – Carpet holds onto lake gunk, which can break down gelcoat over time.
The result? Blisters, bubbling paint, and costly repairs—all caused by a soaked strip of fabric under your boat.
The Gatorbak Bunk Cover Advantage
Gatorbak synthetic bunk covers were engineered to fix exactly this problem. They eliminate the causes of hull blisters by keeping your trailer bunks dry, clean, and breathable.
