My project is a 30 foot Glen-L 'Francis Drake' cutter in 'glass. The
plans specify an engine of between 10 - 20 hp; I'm thinking of using
the various 3 cylinder Kubota derrivations from Beta/Universal/Phasor
rated at nominally 22 HP (about 230 lbs).

These plans (and my contruction) have floor timbers at 18" intervals
spaning the bilge. The engine beds are two, 1.5" net glass covered
wood (vg fir "2 X 10" in my case) rabeted into the floor timbers
(runing longitudinally) and spaced to accommodate the engine. Into
this one bolts gusseted 'L' brackets of galvanized steel onto which the
motor mounts are attached.

A picture may be worth a thousand words; email me off list if
interested.
