> 2) Hull condition - Any leaks?
Slow leaks in both hulls, a little worse on one than the other. I am
pretty sure it's not the hull itself, but probably deck hardware.
After a couple-three hours of hard sailing, you get a gallon or two in.
2-3 gallons sounds like alot. Before I'd jump to conclusions that you need a resurfaced bottom ... and if you're serious in purchasing the boat ... you can check to see where the leak(s) are coming from by doing an "air test".
This is performed by removing one of the port hole covers. Next take a blower--something like a leaf blower or wet/dry vaccuum that has a port for blowing out. Insert this into the open port hole and seal (cardboard is good then taped). Next take a spray bottle that has a mixture of water and dish soap. Spray on hulls and look for bubbles. voi la . The first leak...continue on rest of Hull 1. Repeat for hull 2.
>There's a minor
delamination at the end of one daggerboard that I would deal with
before sailing her, just to keep it from spreading.
I wouldn't worry too much about this ... yes it'll need repair but you'll be doing alot of this type of (minor) repair to your foils (daggerboards and rudders).
