TowBot
« on: January 26, 2021, 10:16:16 PM »
I started a rambling blog post that will mostly center on my TowBot project.
https://www.ponostyle.com/towbots-and-silliness/
I'm going to use the post to record all my work until it gets too clumsy, then I'll probably add new sections. this first post is mostly about electronics, but I'm working on the design of the hull as well. It's going to be a catamaran with rudders on both hulls and the propulsion on a foil mast in the middle. Here's the sexy beast that going to push this thing:

Foote 10'4X34", SIC 17.5 V1 hollow and an EPS one in Hood River. Foote 9'0" x 31", L41 8'8", 18' Speedboard, etc. etc.

That is one sexy but of kit!
 This might give you some ideas for the hull.

That's very cool. I've seen quite a few moths sailing in Cascade Locks, there seems to be a fleet of them there. I tried to get one when they first came available but the guy I was trying to buy it from (a Russian small boat builder) turned out to be running a scam, or was just incompetent. Never got it. There are some small, very fast hydro sailers in Mission bay, but I don't know what they are. they look like slightly bigger moths.

This looks more practical. But the hull I'm going to use for the TowBot is based on a very simple catamaran design that needs no molds or jigs. Super simple. I might even build a full-size version and add foils to it. This video is probably more info than anyone needs who isn't going to build one, but the basic construction of the small prototype starts at about 15 minutes. He builds a prototype hull in real time in about 15 minutes not including glue setting time.

For slightly more sophisticated hull form, but still simple to execute, consider Rob Denney's "Intelligent Infusion" approach at http://harryproa.com/?p=1845



Note that his proa hulls are formed in two halves, with the seam running down the centre of the deck and bottom. You could adjust the method for conventional symmetry by making your tooling for full bottom and sides, then glue on a deck after fitting out the innards.

(PS - I want to build his EX40)

Something wicked this way comes--I just kind of like looking at these. So much potential.
