During spring prep I notice some significant cracking on the (Starboard side only) bow of my 4 year old H240 that has me concerned. There is a fine crack that runs parallel to and about 2 - 3" back from the bow and runs from the deck to the bottom of the bow .. it also radiates in a loop back from near the mooring eye back beyond the anchor locker drain .. the more serious part of the cracking is near the waterline where there is some relief to the cracking that you can feel when running your hand over it .. with all this there is no apparent center spot to the cracking and the boat has never had any kind of an impact that would cause this damage. Has anyone every experienced any similar problems with the H240 Hull?
