got a 370 Sundancer with Caterpillar diesels, Tracking satellite antenna, two DSS receivers, three tvs and a portable 15" flatscreen on a 15' cord to use outside, icemaker, big stereo, ps2, n64, full electronics with autopilot, and a lot of other things that mask the simple "boating experience". We basically live on it in the summers, only to come home to do laundry every now and then.
For a more "spartan" boating experience we have the Formula 311SR1.
The 311 sleeps well, and am planning to add a Mermaid Marine A/C under the sofa cushion (35# and $1,300 for whole deal including reverse cycle heat). This unit will run off a 28# $650 Honda EU1000i mini-generator and will still have enough kick left to run the charger (keeping the stereo and fridge going).
Only thing is to figure out the best way to duct the exhaust from the generator out of the engine compartment. I suppose I should make some sort of exhaust coupler that has a water jacket on it to cool the exhaust and then run it out an above-water thru hull. Figure it can go out thru a small bronze thruhull once I cool the exhaust.
Honda also makes a 2000 watt version that is only 2" fatter and 12# heavier. Also holds more gas and has longer runtime than 1000 watt version. Cost is $1000 vs $650 for the 1000watt.
The water pickup for the A/C, I haven't decided whether to make it work while underway, or just put in a thruhull in the transom to use the unit at rest... I don't want to put a water pickup on the bottom of the hull, but also don't know whether it is okay to tee off of the freshwater pump on the motors. Maybe it would be okay to tee off it if I put in a flow reducer to keep it from dumping too much water to the A/C - any ideas?
