Initial gen set is Fischer panda 12 kw. weighs 186 kgs (plus fuel
tank), dimensions are h 580 l 700 w 470 It could go under the helm,
but it limits the possibilities with the steering cables. Easy enough
to get around. We were thinking of putting it under the bridgedeck
table (when I get time toi draw it!).
Instruments on a turntable is a good idea, but we will probably have
them up against the salon wall so they can be turned and seen from
inside. The tray on top (with clips) is an excellent idea. Holding
onto, and trying to read a flapping chart is no fun at all.
The wiring will run in either conduits glassed under the bridgedeck,
or along the inside of the beams.
JT, We are still waiting to hear if a complete 110V system is
practical. Owner wants to use househiold appliances as they are
chepaer and easier to fix in out of the way places. Be interesting to
see how this works out. I have forwarded him the 3 wire system, which
looks like the way to go.
