I dont like the idea of forward facing props. I feel like they pose too much risk to other water users if I do something stupid or the board gets away from me, for whatever reason.
This was the easiest/lightest way of achieving the goal.
This builds key objective is to keep it light.
My plans are for a sub 6kg 130L 180cm SUP with 7s8p 28Ah battery (3.2 kg) and a VESC 6.
I’ll consider it a win if it comes in under 16kg all up.
I wont be riding this for a while due to injury, but I’ll let you know how it goes Feb/March.
ok, your joint has the perfect surface, you molded it into what, how did you make your mold, once the joint is done you glued it on one side on the surfboard
Oops, I posted up on the wrong thread about this. I am super psyched to see this latest configuration - I’ve been dreaming about something like it for a long time now.
My thought is that it could be used with a very small (and light!) high power battery - maybe something like one of the bigger power tool batteries. I’d only need a few minutes of run-time to catch a few dozen waves. I really don’t mind prone paddling the board out to the break, or maybe just run the prop at a low speed for a little assist. Then use it as a burst to catch a fast moving unbreaking wave. Sometimes the biggest waves come through so fast it can be really hard to catch them even with a standup paddle foil board. No problem to ride them once you’re up on foil though.
Or use it for getting into swell downwinding.
The key would be to keep the build as absolutely light as possible so the board still surfs well.
Tell us more about how you are thinking to use it - like I described or???
The battery I’m going to use is a 7s8p li-ion. Weighs about 3kg.
I’m pretty much going for what you have just described.
The setup from my calculations will be about net 7kg positive, so I’m still going to notice the weight. It should be a lot more enjoyable in the surf compared to a 26kg efoil though.

Hi, I’ve read through the conversation but couldn’t find info how did you make blue gasket.
How did you manage to get it on the vertical side of opening?
I just used the Wagnersil 32 N Premium Silicone, which is similar to Moldstar. I used it to make my mast plate gasket and I did not use a release agent. It was easy to take it out.
Hey Michion, i’ve just joined the forum and super interested in efoil systems to catch waves, I live in Raglan and have been foiling the bar for the last year (quite a lot!) i see you are based in NZ(?) and was wondering of you would be ok to catch up for a chat as id love to get some more insight into this amazing area of foiling! I have built ebikes and drones for years so know a little bit but would appreciate any time you could spare, thank you! (my number is 021449432 if you want to txt)
