Yes, this 3 blades works like a charm, I feel like the tow is smoother, more stable especially in the chop because like on foil assist you always have one blade in the water so the reentry has a better behaviour regarding cavitation
You have less top speed so it’s easier to manage the trigger, it’s less sensitive in 12S.
At top speed you draw more current but it’s not the purpose of tow boogie
Are you happy to share your ProtoTi order number (perhaps as a DM), so I can make an identical order? They’re China based so shipping might not be too bad for me in NZ.
Stumbled across this board from 7Larky who make the foil assist kits with all the parts in the mast which is a great concept. This “3 in 1” board has mast rails near the middle with the intention to be used as a boogie, as well as a foil assist board, again a great concept but I wonder how well it works. The Seven Larky 3-in-1 surfboard
I don’t know if this is right place to post maybe should start my own but I tested my boogie today with my assist battery which is 12s3p 50p molicel pack.
Boogie has dual maytech 6579 motors , 160amp waterproof esc on deck in elements, props are from Kparts not sure of pitch .
Roughly similar measurements from Jezzas surf boogie build. 10m wake board rope.
I was on a 80l apple tree slice board with Ha980 wing with 205surf tail.
I only managed to get on foil twice spent a lot of time falling off board. Trying to start on my knees I can’t seem to balance and sink with feet. Once on foil it didn’t seem to have enough speed top end or when I tried full throttle front right side of nose was lifting and props air rated so lost thrust to stay on foil.
I will go back to 1250 or 1550 foil to learn and maybe longer board.
My question is what is causing board to lift what do I need to change in my setup
other than heavier battery which I will be going with 14s 14p, will that give me more thrust and top speed?
Front of motor pod to tow point is 850mm
Front of motor pod to back of board 660mm
Centre of battery box to front of pod was 450mm
Board is 5’8” x 22” x 6”
Any help much appreciated
On a similar note to @Airtimeasto could I get some advice on my tow boogie? I’ve had one outing on it so far. I used a 7ft DW Sup board and the huge 1300 v2 axis foil. It got up but I did have to pump the board a couple of times before I was on the foil. I am running 2 x 6384 motors with the Bremote. The battery was a combination of my foil assist packs so only 12s4p p45b cells. I will be building a bigger pack once I’m happy with the set up.
I was expecting more power as I was hoping to use it with my prone board at 50L and something like the axis 999 v2 foil.
Here is a clip with a GoPro mouth mount from the first outing. I’ve tried to replicate the very successful @Jesserosco tow boogie build. Is the aeration you see behind the board normal? I’m thinking I’m losing a lot of thrust there.
I’ll test it with a smaller board and foil soon once we get calm conditions again.
Thanks I’ve started rebuilding the flat bottom end on the board again this is my old wing board. If this is successful I’ll shape up a wider board design.
How wide is too wide. My foam block is 60cm wide? Also I will only add V and rocker in front and rest flat.
@Airtimeasto and @nekitesurfing I had similar issues to both of you on my first two tow-boogie boards, and wish I started with a boogie board just to get it working.
First one was an old prone foil board, too much drag, too much pulled in tail (viewed from the top). Similar to @Airtimeasto. I don’t think that board is the right idea at all. You should try a square tail with parallel rails otherwise it sucks down too much. Look at hadou’s thread where he adds pool noodles to square out the tail. I think this board might not be a great base, but could be solved by fixing the tail
@nekitesurfing my next board was similar to yours, I only had one motor, but the tail rocker and pulled in tail (viewed from the top) doesn’t seem like a good fit. Maybe your problem is different, as the double motor should have easily enough power to pull you up on any foil and board. It looks like you are getting crazy cavitation… which I try avoid on mine and only get when it is choppy. I think you almost certainly can get this working better by reducing cavitation, but I have no idea how.
A big boogie board was easy and worked with nearly zero tweaks other than adding nose rocker.
@nekitesurfing what props are you using? It looks like theres alot of air there. I got a boogie with a one motor built on a catchsurf beater board so not really surfboard but not really boogie board and it works ok. When it torque rolls the motor breaches sometimes and it aerates like that with loss of thrust. Yours isnt breaching like that so might be the props causing it?
Thanks for the reply. All tips appreciated. I’m hopeful this can be solved. I’m thinking of how I might be able to make the tail less pulled in. I’m wondering if I can attach anything to the sides….
