Build a boat... keep track of everything.
When I built my Tolman Alaskan Widebody Skiff, I used cutting edge project management technology to stay on top of each step, and keep things under budget.
When I started commercial rod and reel fishing my Tolman Skiff, I decided I just wanted one place to keep everything: Receipts, Maintaince Logs, PDFs of engine manuals, fisheries guidelines and regulations, but mostly my punchlist of upcoming todos.
So I decided to just build the thing. I happen to like Tolman Skiffs and Classic Seacrafts (sites below), but whatever your hull, I hope this is useful to you!
