I loved building the i550 and I had a bunch of great sails on it. But I can't believe I passed 17 years without having a boat upon which I could sit comfortably below, eat lunch and maybe even take a nap or overnight if I wanted.
I think I spent perhaps 3 or 4 nights sleeping aboard the i550 and it was marginal. And not afloat, unless you count a floating dock as "afloat."
But having a boat with furniture below and an actual keel and all the stuff that's needed to venture out and keep the rig pointed at the sky means: lists. Lists on keelboats only persist, they never completely disappear. Soon as you whittle something off one end, something else pops up on the other. I sat below and worked on mine.
It was 64 degrees in the cabin and that was excellent.
Lots of ducks, (ruddies) and geese, but still zero osprey.
