Re: S&G: 90 degree corners

: Simple as it looks, it probably IS overengineered.

: 1) The fillet may look cosmetic, but it can fill the gap for
: aerodynamic (or would that be hydrodynamic?) form.

: 2)The strength of the bond would be similar to the bond strength of
: a proper fillet of the same dimension. The base of that fillet
: has a relatively huge surface area in relation to the amount of
: weight or pressure applied to it. A fillet of the same size
: holds the boat's panels together--this one just fills a gap.

: On second thought, someone could make it simpler still and replace
: it with a bead of caulk as shown in the illustration below. The
: idea would be to put a release layer (wax, grease, saran wrap,
: or tape) on one of the surfaces and have something to limit the
: depth of the bead of caulking material which is applied. That
: would keep you from putting in too much. The boat parts would be
: assembled, but not drawn together to full tightness, the caulk
: applied and smoothed with a wet finger or squeegee, then allowed
: to set. The boat would be disassembled and the release material
: cleaned off. The bead of caulk remains glued to the other part
: as a cast-on-place gasket. One could use a flexible silicone or
: urethane, or an inflexible caulk for this.

: More ideas. Who'd have thought.

Actually the sealing gasket probably isn't required, not likely you'll keep the water out between the hull sections anyway. Sealing the fasteners that hold the parts together though need sealed, but rubber washers should work fine.
