Joe, I too would most likely make some mods! However, to my thought.... the 19 would be the most upgradeable of the 19' O'Day models with a cabin, what she lacks in topside "beauty" is more than made up for in what looks like a very useable cabin, inviting several "easy" upgrades in my opinion, like adding a rudimentary galley, enclosing the head (well, not for privacy, just to hide it when not in use!), etc. The main hatch might not be necessary to change.... but I'd definitely add windows to an early model that came with out them.
PS: There is a 19 in SERIOUS need of TLC just up the street from Rudy's location......... Hmmm? Maybe someday??
