I guess I don't quite follow how your boat is set up (the drawing on Saildata is fuzzy). Do you have any pics? I enjoy redesign projects in boats. I'm a design builder (housing). Small space design - like boats - is the most interesting.i use the quarter berth alot on both sides the icebox is starboard as is the galley i can have 1/2 of the countertop still useable and the lid of the icebox will be flush as well i have about 24" of depth under the counter to put it in but want to get 4" of insulation to get better R factor with out going to the aerogel panels
the refridgeration would be a holdover plate running off the engine directly so no power involved just need to runn the engine twice a day for 15 mins each which is normal for setting and picking up anchor
We all sail differently. For me, I often sail on and off anchor and like to be able to stay for a few days. We have plentiful ice available in my cruising grounds and we're coastal sailors that are gone short term.
