Foil Drive Session - 8/6/2026

The waves were a little bigger than they have been - so I figured I should go.

And as luck would have it - the wind seemed to be strong enough to parawing...


I brought the Foil Drive.

AFS Enduro 900/Mako Carve 130 - on the AFS UHM 75 cm mast.  No.40 had board duty.


I paddled out with Robby - and he went in before I did.  Prayot was out on his DW/Surf SUP.  And Roland was finishing his setup when I came in.

There were some decent waves if you were patient.


But it was rather choppy from the wind.

And with the shorter mast on the system, I found myself wiping a bit more than I normally would have.  2 inches does seem to make a difference (especially in chop).


I'll call this 15 rides.  I know I had a few shorter ones, and even some wipeouts.



The forecast looks doable for parawing tomorrow!!!

Prone Foiling Session - 3/6/2026

And in the afternoon, La was working on some projects, so I figured I'd hit the beach.

These guys were chilling.


And Kalani had sent video - it seemed junky so I figured I should practice prone foiling again.

Silk 1050 on the long fuselage with the Silk 142 rear stabilizer.


I don't remember how taxing prone foiling is... definitely humbling.

I actually feel like I surf better than I prone foil (which used to NOT be the case).

I can say with confidence that Foil Drive-ing makes your prone foiling SUCK!!!


HUGE difference in track patterns in FD and PF.


I did manage to get three rides, with the last one being more indicative of what I used to get (before Foil Drive).  Having the Silk 1050 on may have been a factor...

I did make an adjustment on the mast position - moving it forward a notch and it did work better.


I think next time I'll use the Uni Progression 170 - and continue using that foil until I get used to doing this again...

Evening Prone Foiling Session - 2/6/2026

I had two rest days in a row - today was a get out and get some foil positions down on No.43 day

The waves were generally small, but they were supposed to pick up a bit and the tide was coming up - so generally a favorable forecast.

These three were basking - we don't usually get three this close in proximity.


No.43 with the AFS 75cm UHM mast (freshly modified), Modular Silk 1050/Silk 142 mounted on the standard Fuselink fuselage. 


With the waves on the small side, prone foiling was even harder than it is normally.  And it didn't help I was trying to be extra cautious with the new foil.


After a long wait and many failed takeoffs, I finally caught one and got up to ride.  The Silk 1050 is amazing!!!  Turns super hard, pumps through flat spots and is uber maneuverable.

On this wave the system felt like it could use more raw lift.  I moved the foil forward and tried again.


The second wave I caught felt way better -

The pressure felt balanced front and back, and the turns were even easier to make.

Both waves were decently long, but with low wave energy, I had zero chance of pumping back out.


Prone foiling is no joke - I'll mix this in more to regain my proficiency.

Garage Works - 2/5/2026

I ended up taking another rest day (waves weren't supposed to be that good).

But in the interest of getting prepared for the next few days, I knocked out a project I've been wanting to get on for quite some time.  The AFS UHM 75cm Skinny mast had flat (pan head) bolt holes.  I use countersunk bolts - so that was a problem.

If you use countersunk bolts in a flat hole, all the pressure the bolts transfer to the mast are done so in point loads 


I dug through several spots in the garage until I found this - a countersinking drill bit.


Here's how the countersunk bolts sit on an unmodified bolt hole - proud by a long shot.


And here are the bolts in a hole that has been countersunk.

Nice and recessed.


The load is now spread out over a much larger area.


Just in time to setup a prone foiling session...

Prone Foil Dawn Patrol - 12/26/2025

Nice conditions this morning.  Waist high waves combined with the high tide, made for good prone foiling conditions -


And I took out the AFS UHM 75cm mast (ultra skinny one) and the AFS Enduro 1100 - first time for both of these on a prone foil strike mission.


I did not have a lot of time this morning - Noe asked if I could take her to the gym on base.  That was the other reason I decided to prone foil this morning instead of bringing out the Foil Drive.


I caught three waves where I stood up and got some down the line time, some fun carves, and on the last one a pump out the back of the wave that took me in.

The tracks on No.24 are quite short and set back pretty far.  When I built this board, the foils that were used for prone foiling were on the high side of 1300.  For prone at my weight I am bolting on foils around 1100 sq cm and it is pushing the front limit of the tracks (which is why I am building No.34)

But I still got the Enduro 1100 close to where it should be (it could use about a half inch to slightly more forward space).


This looks so different than a Foil Drive session -


It is good to mix things up to keep the mainstays fresh.
