Si

Just a little advice the heel edge has to much curve and needs to bee straighter because when your riding on the edge it will rock and become unstable. Another thing is keep the ends flexi and the centre stiff if you can it will help a lot in chop.

Good luck Buddy

Cheers guys, not had a chance to finish it yet, but thanks for advice.

The edge is straight for most of its length, first photo is how it looks. Last photo is illusion due to rocker!

Tempted to stick on a bit of resin, straps and try it before spending time finishing properly in case its a dog!

cheers si.

I'd like to build a twin tip speed board. No intention of competing, I'd just like to kite fast under control in 4 inch chop. What is the recommended rocker for a twin tip speed board? What kind of board speed can be obtained on a twin tip speed board in 20-25 while bearing off 10-15 degrees? Thanks for any info.

You need a flat surface put some Perspex on it or thin plywood with a plastic sheet on top of it place a 20cm wood block under each end.
Board 140 to 150 in length 30cm + in width with straight rail
What are you thinking of making it from ? And how much have you budgeted for it ?
You will need a board with flex in the tails + a 2kg lead weight would help keep the board down over the chop but its your board and up to you how you make it

10 to 15 degrees is not broad enough you need to go much more off the wind than that to get a good speed and flat water would help
But I would think you can achieve 30 / 35 knots AV over 500m maybe more

You don’t need a vacuum pump to make a board

I can PM links of suppliers of materials

Thanks for the reply and for the offer of materials info. 10 to 20 degrees off a beam reach is about as low as I can get (in flat water) at my kiting location when the wind kicks up. What is considered the ideal angle for max speed with winds of 20-25?

Hi there, sorry for the spam but this might be of interest if you are reading this thread.

Got various bits and bobs lying around that will get you started if you are considering getting into board building/repair.

Fatherhood means limited time on the water and even less in the workshop! :-(

3 litres of expoy resin (resin research) - Brand new/unopened £40 (with P&P)
4 inserts (0.8mm) with the little magnet at the top so that resin does not get in. £7 (with P&P)

Various bits of fiber glass mainly 200g/sqm (pre cut 150*50 cm if my memeory is right)
biaxial 400g/sqm - £40 (with P&P)


If you take the lot I will put in the remaining brushes, squeege, silica and other sundry I have.

£80 for the lot with P&P
Get in touch via OM if interested.
