I am the first guy to have a full synthetic teak cocpit... I may well be the first guy to have a real marine genset too!
I decided lat last night that I want a real marine genset. The LOGICAL choice is the Westerbeke 3.0 gas which has the smallest form factor of any generator, weighs in at 165lbs and puts out 3.0KW at full load (more than enough to run everything on the 248!).
So my plan is to eliminate my hot water heater and replace it with a much smaller "instant" 110V heater and all the space I will gain to port side will be where the Westerbeke will live. This is not a chore for the faint of heart, the price for the genset is approx $5400.00 and that does NOT include the lift muffler, thru hulls, strainer, anti siphon fuel tap etc.. But you know what? It's WORTH it! To be able to run the generator all the time (even while moving) charging batteries, running the AC etc etc.. Plus I am adding more value to the resell of the boat AND I won't feel the need to sell it and get a 318 next season
Honestly the 248 is a perfect size for me and the only main complaints I've ever had was A: Lack of a generator and B: Lack of a radar arch, and I am going to remedy both of those issues!
