Defects and Damage
What structural damage does an impact cause in a GRP hull?
GRP takes an impact at a point but spreads it inside: a small mark outside can sit over delamination covering a far wider area. The boundary of the damage is therefore established with a hammer rather than by eye.
Why it works this way
An impact is also transmitted to the backing or stringer on the far side, so the inside of the contact point is inspected as well. Repairing only what is visible leaves the structural half of the damage in place.
