Crazing is usually due to flexing or hits. Star cracking is usually due to strikes.
Long cracks along inner edges of the sides of the decks or cabin
joint or near the winch
are might indicate a lack of layup
in those areas as they get stressed.
If the main cap shrouds are attached to the cabin
top, it's flexing.
Not good, should have supporting structure under.
