You guys lack vision...
Imagine if you will, being able to stay anchored out in a remote anchorage for an extra couple weeks because you haven't wasted precious diesel on keeping the boat warm. That, and knowing my wife is happy when I'm out hiking/photographing in the pouring rain.
Nothing like the penetrating warmth and sound of a crackling wood fire with torrential rain drumming on the roof
I'm pretty much kidding... there's usually plenty small pieces of wood for FP on beach.
However, if you are in cold weather or damp days or hard to get at beach-side locations I can see retrieving much satisfactory wood a chore. Boat big enough?? Load a 1/2 cord split oak and small rounds aboard for when beach wood is scarce.
