I built a 12 foot boat in my living room. I had an old car, sold it and used the money to buy the lumber
, a bunch of tools, glue and everything else. All total I spent about $3600. That included the trailer and a trolling motor
and the biggest battery
I could fit in the battery box
. I could have done it cheaper with what I know now. Instead of premium marine plywood
I could have used exterior plywood
and epoxied the crap out of it and fiber glassed the entire hull
instead of just joints. For $3600 I could have bought a much larger boat off craigslist or any of a number of brokerages that sell used boats.
I can sail my boat, row it or run under power for 4-5 hours. It's great for fishing
can be replaced for $30 and made in an afternoon.
I used premium lumber
and lots of glue, epoxy
and 3m 5200 and so many screws...so many screws...
I know every goof-up, screw location and I worked my butt off for three months to build it and then another 6 weeks of anguish getting the title and hull
ID's from the govt.
It suits my purposes completely, it's fun but I could have definitely gotten on the water cheaper. I also learned how much I didn't know. I didn't know how may types of glue there are. I didn't know just how rare #8 wood screws in quantity are. There are so many variables and pieces of hardware
where I followed the plans and went the cheapo way, eg; barrel bolts instead of pintles and gudgeons.
I added extras like more life jackets than the boat can carry people, a porta potty and store bought oars and fancy oarlocks. Waterproof tackle boxes to carry stuff in, etc.
For $1000 more I could have had a 22-26 foot boat on a trailer that only needed some cleaning
I wouldn't change a thing and in three years I'll get the bigger boat. You can watch the process here along with other videos of the first launch and my first couple of times of actually sailing (ever).
The main thing I've learned is I don't know nothing and the more I learn the less I know. I'll spend the rest of my life trying to learn enough.
