Alex The liner is a void (no floatation) up front. The liner is bonded in the hull with wet mat that is resin impregnated. After we lower the liner into the hull we clamp it all around until the resin hardens. A soft spot in the liner Is not serious. The hull deck joint isn’t related to the liner in anyway.

Is simply a gap between hull, hull liner and deck, or is there some kind of core or structure within? I’m thinking it is a void, and any water entering through a an exterior crack at the deck/hull joint would run down that void and end up pooling up against the bulkhead under the v- berth (where the lump of ballast is in the older boats). Or is there some kind of filling or structure in there? 2) how is the Is the hull liner in the cabin bonded to the hull? Is there any kind of material between the two? I have a section of hull liner in the very bow that flexes as if it it is unattached to the hull, and am wondering if it matters enough to drill some holes and try to rebond it. Send an earlier email with no response, so am trying again as I really appreciate this groups insights and knowledge! Alex
