I think tager on the right track, get what's important accomplished, if it needs sails, run'n rigging, seacocks etc,etc. do that first. work the deck little at a time, go sail when you can, work on the deck when you can't.
If your lucky you'll have break points in the deck, allowing you to do sections at a time without a visual break point in the final finish. When I did my Islander, I did elec. first, then new outboard, then rigging, then sails, then repaint ( with Brightside ) the cabin, then foredeck, then sidedeck, then cockpit, then refinished the spars, then all new canvas.
Took 10 months but, we sailed when we wanted to and worked on the boat when we didn't. In the end, what started as a eye sore taking up slip space, that people were tired of looking at ( before I bought it ) ended up having those same people waiting for the forsale sign to go up when they heard I bought another, bigger boat. It sold within 8 hrs of putting a sign on it
Same thing is happening now with my Tayana, ....................
Ya know, coming from offroad racing background where you come home on a Sunday afternoon and by 8pm the bike was in 100 pieces with only 7-10 days to get it ready for the next event, the hardest thing I had to wrap my head around when we started sailing was, in sailing there is no clock, sh*t gets done when it done, in the meantime you try to enjoy it
