Other boats are needlessly used in a careless way and this causes hull problems. Never allow someone to load heavy objects on the cabin top or jump onto the deck from the dock. Not only is it dangerous, but it can lead to delamination in these areas which will grow with further vibration from normal use.

Fiberglass decks can delaminate from their core over time even if the core is dry. Here is how to fix that problem.

My theory is, that the old teak deck might have been leaking from the screwholes, and causing core delamination. And then the teak deck was replaced without paying attention to the condition of the deck core. The boat is now 22 years old and the deck has Divinycell-type foam as a core material.

There are some exceptions to this, particularly if you have a molded surface such as a hatch opening or non-skid that would be hard to

It can also detect delamination within any of the layers of the fiberglass, including delamination caused by osmosis (blisters) and disbanding of the layers adjacent to the core. The vast majority of boats are manufactured with a cored deck. Hulls, stringers and other parts may also be cored. Coring is usually
