Thank you so much, my boat is owner finished and I wasn't sure what factory spec was. I'm short about 5'10" and I'm thinking about adding a bilge, water tank and raising my sole 2" which will widen the soul to 24" and still give me standing head room.
That's a really good question. Ideally I would like 30 gallons in a single tank and an addition 25 in portable tanks. I have an owner finished FC with no engine, no head and no tanks so its an open book.
I've only had her 2 years but am learning fast that weight distribution is critical on these boats. I have been using 200lbs of dog food and 10 cases of wine as movable ballast to determine where she likes the weight. Ideally I will have a deck mounted box with a gravity feed water tank that also fills my main tank from a rain catch. I wish I had access to a few factory boats so I could compare layouts.
One thing I love is the 6x6 laminated keel stepped compression post but it does rob some space in the galley and bilge, where my tank will be. One thing for sure I can pile 2000 lbs of crap/food/booze in this boat and still not be down to her DWL. She seems to prefer more weight, and sails great loaded as long as I keep her steering sails flying longer than her driving sail.
I measured my sole directly on the plywood underlay and at the widest point (across the quarter berth bulkheads approx 39" from main bulkhead) I got 20 3/4". I remember someone stating that the later FCs had a raised sole so that they could put in two water tanks made by Ronco (part number B341) with each one being 9 gal. Added to that is the plastic water tank under the engine which is 23 gal. for a total of 41 gal in a factory Sam L Morse FC. These will also add some more weight down below. I hope this is helpful.
Yeah I'm not sure how much of my boat is factory, I talked to Gary the second owner and he said He ripped out a bunch of the interior the original owner had built. For the record my headroom in the center is 72 and 1/2".
