If you are in the main saloon
when a cat capsized, you would be immediately submerged. The thought of swimming up
to one of the hulls in hope that the hatches functioned as advertised, bearing in mind that you would be otherwise trapped there, just doesn't make sense to me (fans of the Poseidon Adventure be damned). I would either exit through the companionway
, or one of the large hatches at the forward end of the coachouse.
On the other hand, if you were in one of the hulls at the time of capsize
, they would be a nice option. The real question, in my view, is whether they create more problems than they are apt to solve.
On the issue of positive flotation while inverted, it is absolutely true that the foam core
alone will be insufficient. One must either rely upon the air trapped in the inverted hulls (and for which holes in the now inverted hulls would
be detrimental), or water-tight collision
bulheads, both fore and aft. Fortunately my boat and many earlier cats have the latter; sadly, many of the newer designs where the diesels have been moved out of the accomodation and aft of the rudder
posts, do not (or at least, they do not have very large
flotation areas aft). That also explains the picture posted here on another thread of a holed Lagoon
that was afloat only at the bows.
