Working on a new version for my tow boogie.
Currently cutting the foam.
New goal is to make it easy to set up and assemble.
I would not compain if it also turns out to be more stable.

Got a few steps further.
Its so refreshing to build a board and not having to save every gram of weight.
Laminate is one layer 750g triax glas.
Super easy to work with, unfortunately too heavy for normal builds.
I will recycle my motor mounts but got inspired by the inflatable with the plate on the top and now have the plates on the top. which should make it much easier to assemlble.
My motor mounts are based on 40x20 alu extrusions with 3d printed cover attached to an aluminum plate that used to be on the bottom and will now be on the top, with the extrusion going thtough the board.
If everything works as planned, this should be easy and quick to assemble with just two m5 screws and be super rigid. I added some extra channels, in case I want to try different motor positions.

Recycled motormounts are working as planned.
Really quick to mount and super rigid.
V2 ready for water testing:
Added an external antenna, so this will hopefully improve the reception issues I had in surf.
Full setup now a bit more heavy than I would have expected.
Is the tow point just printed?? I think it will need to be stronger than that. I’ve had a couple
of people bend 3mm stainless rings, and have increased them to 4mm now! Maybe a glassed loop tow point like some surfboards do for leashes??

Yes its printed.
But its also recycled from previous version.
And was working without issues.
It is solid 6mm TPU for the base with forces going 90 degrees to the flats.
The area with the ring is 20mm solid TPU.
Its probably going to rip my arm off before breaking.
For the base - its pulling upwards.
So to break it would have to tear 6mm TPU over 80mm wide.
This thing also started its life as a “ring”, 4mm stainless.
Very nice and looks similar to my napkin sketches for me v2. What measurements did you land on for the hull?
1440x550x200.
In hindsight I would downsize a bit, likely about 1350x480x200.
