Keep focused on getting it on the water.
You keep mentioning paint, and designs - that's the last of your concerns right now. New Gauges?? That's gonna be a couple $$ too if ya want the pretty billet and Bling.
Get yourself some good reliable motors and drives, and put you're $$ into the rigging. At least get functional gauges, and build from there.
Vinyl work, if not too complicated, is pretty easy. I re-did the entire Cockpit and sunpad of my last boat over a winter myself. Bought a sewing machine and a few $100 in marine vinyl and went to town.
The paint can come later.
Actually, I don't mind the plain white wrapper look. But, it could use an accent color. Too wild of a paint scheme on that boat would look silly IMO.
BTW - It's a great looking boat.
Keep us informed WITH PIC'S of the progress.
