LLoyds has the specks for GRP boats.

Very simple to understand , however the rules are for an all chop boat (or mat) and hull thickness can be reduced with a better (more roving) layup.

Most boat assemblers are very coy about laminate skeds , you may have to pull thru hulls.

These boats have been around a while so IF the hulls were sub standard the bigger problems would be known by now.

Tapping is not as effective as a tuning fork for finding hull bad spots.
