Re: Why are hull/deck joints built the way they are?
I've noticed that "outside" hull deck joints have become more common - where the deck bolts through an outward turning hull flange. Supposedly this detail makes the joint more vulnerable to damage than an inward turned flange but I've always regarded that as a bit of a theoretical reach. Even if true, IMO the benefits far outweigh the potential downside - I suspect there have been a whole lot more leaky inward hull deck joints than outward ones damaged from hitting pilings and so forth.
That method means a single person can bolt the deck on - you don't need a "nut holder" inside the boat. It also means the bolt holes don't penetrate the deck inside the boat so potential leaking is greatly reduced - the adhesive/sealant in the joint can be continuous, not being holed by fasteners every few inches.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
