Alpine, now is a perfect time to design your fuel tanks, where you want to route the fuel lines (and if aluminum tanks remember to install and route the tank bonding wires!), if you want ventilation through the tank/bilge area or not, draw up your electrical diagram, figure out where you want batteries, whether you want a main engine and kicker and how and where you're going to install them, what paint system you want to use, non-skid, etc. There are a million details, and in the times you can't build it's good to talk to people, research, and make some decisions so when the time comes you can just get moving.
Once you flip the hull you can really get into laying out the cabin, back deck, etc. so to some extent that can wait.
I say this because we had a few weeks of delay mid-project when we could have been really cranking when we were testing paints and non-skid and I was shocked at all the decisions to make in this regard, and how hard it was to get some of the products, at least up to Alaska. Also the fuel tanks were more expensive than I anticipated and took longer to get, so that slowed us down quite a bit when we were chomping on the bit to sling epoxy.
Good luck!
