It is a fixed 2 blade prop that I 3d printed. If this is the problem, I’ll be happy as that is easily solved. I’m away from my PC at the moment so can’t tell you exactly but will later.
What props would you recommend? Happy to go off recommendations here.
@nekitesurfing I’d start with the props then, as that is more than likely to just unlock things. k-parts is the only one doing a pair of props for tow-boogie, I have some of their other stuff and it’s good, postal delivery is slow from France though, no courier option.
My trouble was the same as @holagato where the pulled in tail seemed to make the torque roll worse. Catchsurf beater funnily enough looks quite good because zero tail rocker.
@mterea I think the beater is a good shape too, not quite parallel rails but it works well, the torque problems are more because I use one motor I suspect. Im still playing with trim tab, rope length and mast placement to dial it. It wants to roll when Im up on foil at high throttle and turn out on the right of it.
That’s exactly what mine does at high throttle but I’m sure it’s mostly due to the rocker in board and step in tail. I have a new block of foam so might just start again with flat bottom before my bremotes turn up.
Do you guys think it’s better to keep chimes square or deep so boogie sits in water more?
I’m using KParts Ali 3 bladed prop on my assist and they work great with 6384 motor heaps of thrust no air ration. I thought there’s heaps of options for those motors. I can’t find any other options for my 6579 motors. That’s if you 3 d printed them
Ok while my other boogie is getting adjusted I’m starting to shape up new tow boogie from scratch.
Here are my dimensions I’m starting with let us know if they seem a close starting point?
145cm x 61cm x 12.5cm
Flat bottom right through 35cm from nose had rocker and tapers to point.
Centre pod cable exit point to rear of board 50cm.
Prop to rear of board 31cm.
I was thinking of adding 3 tracks and bolt motor pods to a plate so it can be adjustable 10 to 15cm or should I bolt where it is?
Battery will be inside pelican case inside bottom of board low as possible.
If motor positioning is roughly close it will make it easier I’ll just bolt where that is no foil tracks. Saves me a lot of hassle.
Any feed back much appreciated
Back to wondering about one of these pvc kids kayaks. I need a base for my twin motor setup and I feel like a soft top surfboard isn’t enough of an improvement on the basic boogie.
These are cheap at £160 (lifetime wave 60 youth kayak) for something designed for kids <50kg, 1.8m length, and has useful features like a relatively flat rocker, chines for tracking, and I could get it self-righting without too much hassle. Sharing in case anyone else is looking for a candidate option. The spear fishing boats were too expensive.
Seems to be hard to find a good place to mount two motors. The only flat area is in the center?
Also looks like it is pretty narrow.
This looks interesting, would love to see someone make this work since it’s not too expensive. I wonder how to mount a motor (or two) though. i would imagine the entire kayak is hollow and full of air. So puncturing the hull a few times for a mast mount and wire routing would require some sealing strategies.
We previously made a single-motor version, using a 6 kW motor and a standard board.
Due to its limited usage scenarios, we didn’t go into mass production, but we shared this method with our customers, and some people are using it for fun.
The method is simple: after adding a power unit to a hydrofoil board and removing the foil, it becomes a tow board.
Yeah that is what I’m wondering about too. It has the through hole under the seat and again at the feet. I wonder if just injecting expanding foam into it would make it viable to riddle with holes. The kayak is cheap enough that I might risk it.
The other approach is to have a fully open cut off tail, with half of it full of foam, so as soon as it starts moving the thing drains. I’ve been toying with the idea from RC boat self-righting chambers.
I’ve just seen Flipsky sell a 3 blade ABS prop for outrunner motor, is this new? Had anyone tried on their boogie. Says for long shaft but it also appears to have 4 screw holes.
Found this as well. I’m wondering if it is to small of a volume at 117 x 61 x 26 cm. But it says up to 35 kg which should be sufficient.
Especially interesting since it can be found really cheap used in Germany.
need to see the under side, biggest concern would be tail rocker or rounded underside causing it to suck down
Found these pictures. Looks like a pretty consistent rocker throughout the whole underside - so probably not a good match. Maybe a plate attached underneath where motors are mounted and towing rope attached to flatten out the rear. Or some heat gun action.
From the buoyancy I’m thinking about using it the other way around.
This one might not be THE ONE. Anyway I like the idea of a small canoe type boat because they are way more solid than glas or carbon over foam and you won’t have to worry about scratches.
That won’t work I don’t think, very sticky.
I think likely too big, but lots of space to build out a big battery setup if you can trailer launch.
I’ve been thinking that a Kawasaki JS300 or 500 might be a good base. Smallest ski made, I’ve seen few hulls floating around.
i’m going to try that kids kayaka and see how it works
One more idea:
There are these really durable PE plastic sleds Made in Germany. Also possible to use as body board and approximately 40 Liters of volume.
That underside should be close to perfect at least for dual motors - not?
