Interesting thought! Maybe as a thick removable aluminum plate,
bolted on, with a gasket, in a square hole slightly recessed and with
reinforced edges inside for the job? Easily replaced if it eventually
looks too corroded. Of course with composite that'd best be built in
in advance. With an aluminum hull it'd be really simple.
