The boat handles well, the largest waves I have been in were around 10 ft. but very short and sharp. she handled this well, with a fair amount of noise under the bridgedeck. Clearance is a bit on the low side, but structurally no problems there, just the noise.
The bunks are fine, matresses a bit uncomfortable for long periods, but easy to fix. Condensation under the matresses is an issue as in all boats without ventilation under them, but again easy to fix with some of that netting stuff.
Storage is OK but in rather large volumes without seperation, so you will need conatiners of some sort. Acess to under bunk
storage is via the bunks.
Nav station is useless as such, too small, so you have to use the saloon table. Saloon seating is in a curved shape, so you can't use it as a sea berth if you have inexperienced crew on watch and you want to be nearby.
For tropical cruising the
refrigeration setup is very inefficient with the compressor air cooled and in a space with very limited ventilation. I would change it to a
water cooled system to save energy. The rear side of the fridge is not well insulated, look at adding at least 2 inches of insulation where possible.
For cruising in light to medium wind I would suggest that you add a bowsprit and a gennaker, as the boat is sorely under rigged, and if loaded for cruising will not do more than 40-50% of windspeed.
If you go for a gennaker, or for deep sailing with the genoa, I would add a couple of padeyes around where the chainplates are. I use these for mounting a barber-hauler to trim them genoa or gennaker. Also I use them to mount a preventer cum vang when the boom is further out than the main traveller track to optimise sail shape. Otherwise the boom just lifts.
The main sheet traveller on my boat was useless for trimming in anything above 15 knots of wind. I exchanged it with a better system designed for the high loads, and with a 1 x 4 trimming sysytem. Even with this sytem, i have difficulty in hauling the traveller inboard at anything above around 20 knots of wind, so I just urdered an Andersen line
tender. Antal makes them also.
The sheet winches on my boat where too small, as I don't like to have to
head up and unload the foresail for trimming, so I have upgraded to larger Andersens.
I would change all the fixed
rigging if this has not already been done. Also chech the main halyard sheeve at the top of the
mast.
Check that you can charge the house bank from both engines, and that you can start both the engines from either the house bank or the start
battery.
For serious cruising I would go for an
autopilot directly attached to the
rudder arms, and not the belt driven
wheel pilot as these can better be tuned to different sea states and wind directions to minimise power consumption and keep a better course.
Check the balsa cored decks for delamination/moisture as I know some FP boats have had issues with this.
Get a surveyor who knows multihulls!
Good luck
