"Blue water" construction is generally more robust and heavier than the typical daysailer or weekend puddlejumper. In a fiberglass boat, the hull/deck joint will most likely have an inward turning flange, or include a bulwark to protect the joint. (This is a weak point on Hunters, Catalinas and Pearsons, for example. Their hull-deck joints tend to have outward-turning flanges, which are cheaper to make. The outward-turning flange makes it easier to damage the joint in contact with docks, etc.) On a "blue water" boat, the joint itself will be glued, through bolted (at short intervals) and possibly fiberglassed over as well. The cockpit will be small, so as to avoid a wave filling it and sinking the boat. The main hatch will have a threshold up even with the deck to help avoid waves filling the cockpit and main cabin at the same time. A good book to read would be "Desirable and Undesirable Characteristics of Offshore Yachts" by the Technical Committee of the Cruising Club of America, (1987) edited by John Rousmaniere. The Dinghy Club and RBYC probably have copies around somewhere.
