One thing to consider, if you're attracted to a PortaBote, is exactly where you'll stow it. Remember the picture atoll posted of the little hard
dinghy lying against the
cabin top and
dodger, and his comment that for
trade wind passages, it was stowed on the windward side? This was so that a wave crashed onto the
boat, it would beat the dinghy onto the
deck, not try to tear it out taking the stanchions and lifeline with it.
Now, imagine how to stow the folded up PortaBote. Probably way better flat on the
cabin top, or tightly against the cabin side, than on the side
deck, lashed to the life-lines.
As to nesting dinghies, some friends of ours have one that is actually two prams, one of which can be sailed. So they have a longish dinghy when both are attached, but they are really, a two-car
family, so to speak. If someone is interested, I'll make an effort to get more details.
