Foil Drive-ing Evening Session - 6/11/2026

Waves were smaller today - size where I'd normal bring out the AFS Enduro 900, but today was a testing day.

Second run of the Cabrinha Whippit 850 on Foil Drive.

I swapped out the Tweaker rear fuselage/modular 140 rear stabilizer for the Union 160 monobloc.

Everything else was the same from yesterday.

And from the first wave - the rear foot bias was nearly gone (just an ever so slight bit more back foot pressure required - way less than yesterday).

Which means the 140 was too small for my weight and the conditions.

Not bad stats considering I was using the original Max battery.

The Whippit was easier to use today and that made carving ridiculously fun.

The whole system still felt bogged down - I'm still guessing it is the full motor mount.

I missed more today compared to yesterday.  Waves that I thought I could catch would run under me and leave me behind.

But I did catch 22 of them.

So the next logical step would be to put the Tweaker back on and start shimming the 140 to see where I gives enough down pressure to replicate the lift generated with the 160 attached.

But if the waves are small again tomorrow, I may just bolt on the AFS Enduro 900.

Prayot was out SUP foiling and Roland was out Foil Drive-ing.  Kalani, Stu and Roland went out earlier in the day.

Always fun to test hypothesis!!!

Foil Drive-ing 6/10/2026

We are in between swells at the moment.  This weekend is supposed to be big again.  But for the meantime, there were chest high waves on the sets, a decent mid tide and low wind for the pau hana session today.

And it was a perfect day to dial in the Cabrinha Whippit/Tweaker 390 + 140 rear stabilizer.

Foil Drive Max onboard No.43

I used the wing bolts to make sure I could get the mast position dialed in.

I adjusted the foil to go further forward after each of the first three waves.  I got it in a spot where it felt comfortable, but through all the rides I noted I was really using my rear foot and the setup was pretty pitch sensitive.

Tomorrow I will likely swap out the rear stabilizer for the Union 160 - seeing if that reduces the pitch sensitivity.

What I loved about this foil was how well it carved.  And I'm not sure if it was designed this way, but with the rear foot bias, this foil felt way more like surfing a shortboard than any other foil I've used.  The Silk 850 carves even harder, but it feels distinctly like foiling.  I feel like I can push the Silk 850 harder, and that it is more balanced - but this reinforces my decision to get the Cabrinha Union based foils - they are different than their contemporaries - and because of that they do not really overlap. 

The Foil Drive itself felt a little sluggish today.  Not sure if it was the chop or the unit settings, but something was off.

It may have been the full-bodied motor mount (maybe I was feeling the drag???).

This is definitely a better way to get to know a new foil (unlike the last "wing" outing I had).

As I mentioned earlier, I'll move to try the 160 monobloc rear stab next - but I definitely want to try the other shims on the modular 140 rear stab also.

If you look closely at some of the tracks below, you can see some pretty curvy shortboard surfing lines -

18 rides (with a few others where I didn't pick up the wave).

Prayot and Duke paddled out on their DW SUP foil boards. Kalani and Roland chilled in the parking lot discussing the boom box build, and then ground handling the PW Derek loaned/gave Roland.

Fun session!!!

Foil Drive Session - 5/8/2026

Got out for a quick Foil Drive session this afternoon - had to get back home so I could help La pack for a trip, and then off to the airport.

The waves were more consistent today - almost even too stacked (especially on the inside).  Outside there was action!!!

Paddling out - low tide made for a longer time with the foil directed upwards.

First time getting the Cabrinha Prestige 905/160 out on Foil Drive -

Got some really long rides today - 

The Prestige 905 probably wasn't the correct foil to use in these conditions - I think the Cabrinha Whippit 850 would have been - but this is a test of the Prestige and it's range.

Head to overhead waves.  With the blue props I was actually up on foil before I could pop up.  If I popped up earlier, I would not have been able to catch the wave (this is a style issue specific to me and how I use the Foil Drive).

I know the Silk can carve harder than the Prestige (but the Prestige and the Enduro seem similar turning wise).

And the Prestige felt easier to keep on foil without having to work for it.  I got long gliding runs without having to pump at all.

I think the Enduro 900 is faster???  The chart below says I got this setup to 20.1mph - I'll have to look back and see how fast I usually go on the Enduro 900.

15 rides in less than an hour!!!

Stu had his Foil Cedrus Integrated Aluminum mast out.  He definitely likes it!

Definitely looks like a slippery hydrodynamic piece of gear!!!
