Fibreglass boats have the problem of osmosis. This appears in the form of blisters in the gel coat, which is caused by moisture infiltration in to the gel coat. This causes a chemical reaction forming pressure under the gel coat creating blisters.
The blisters can appear in small or large form in unprotected
fibreglass boats. The osmosis problem can occur at any time dependant
on a number of factors ncluding the quality of the laminate construction,
temperature and type of water. Therefore Skipper's Line has developed a
system for the protection against an osmosis problem and the
treatment
of the osmosis problem.
