Osmotic Blistering in Tropical Waters

Osmotic blistering is a fiberglass hull condition that may appear as bubbles or raised imperfections in gelcoat or outer laminate layers. Warm water, long in-water storage, and age can all contribute to blistering in tropical markets such as Miami.

Because blistering often affects purchase decisions, it is commonly discussed during a pre-purchase survey and may also appear in a boat appraisal survey in Miami report.
