Garage Works - No.43 - 12/14/2025

It's going to be raining and weird south winds for a week.  I'm not anticipating much quality in the water - so I've committed to using this time to make another board.

After much deliberation, No.43 will be a "Shallow" trench board.  This will not be a standard depth trench board.  No.41 really can only be used for Foil Drive.  No.43 will have a channel cut into the center instead of a deep trench.  The channel will just be deep enough to reduce the drag profile of the mast base plate so mainly benefitting prone foiling (or wing/parawing).

It'll still reduce the overall profile of a Foil Drive unit, but honestly with the power of the Foil Drive Max unit, I don't see the need to have a deep trench (or a trench at all).

I am gluing these offcut pieces of foam to start the process.


I flipped the blank to stop the runaway glue.


And I'm going to have to pick a template.


I'm debating on whether to go with a pointed nose and block tail (the standard 5-0 I built No.41 around), a rounded nose - block tail (similar to a Tomo Neutrino), or a flat nosed, parallel railed board.

I'm also trying to decide on the dimensions.  I'm sitting on 5'0" to 5'2", 19" to 20", and 3.75" at the pontoon sections.  So a board that is somewhere between a mashup of No.41 and No.39

The shallow trench will make the bottom more "catamaran" like - but the main goal will be a return to faster battery changes (without having to undo the track bolts), and the ability to prone foil the same board.

When I get home from work tomorrow, I'll trim the excess glue, draw on the template, and get it cut out.  If ambitious enough - I'll try and get the rocker profile roughed in as well.
