Re: Big wings

Hi Tahoedirk, seems great minds think alike. Halfway thru this surf foil build, plywood core with fiberglass and carbon skin. It is 1000cm and about 11% thick, but I am starting to worry that it will be too small. Also the plywood core turned out to be quite heavy so thinking I'll try a foam core wi...

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Some more speculation: I think the top kiters are getting 15 knots vmg upwind based on 45degrees to true wind and 21 knots speed. Looking at the AC tracks yesterday in 9 to 10 knots of wind i think they are closer to 60degrees to true so the cosine of 60 is .5 times speed of 25knots gives vmg of 12....

Re: 7 kn of wind, who will win AC45F (America's cup boat) or kite foil?

Been watching the AC races, looks like Kiwis are on fire. But I notice that in 9 to 10 knots of wind that the AC cats tacking angle upwind looks pretty shit compared to kiters plus they sail pretty low after each tack to get back up to speed. Anyone have the cat's VMG numbers upwind and downwind? I ...

Re: Wing and stab design

I built the wing the hard way. Hot wired some foam cores for a plug, glued them together, covered with fiberglass and epoxy, lots of sanding, then built a mold. Once you have a mold, making a wing only takes 2 hours. But I think you could build a pretty good cruiser wing by shaping a plywood core an...

Re: Wing and stab design

Hi Tom, I made a bigger wing for cruising on my Moses Comet when I am not in the mood for riding fast. It was around 600cm in surface area and about 11 to 12% thickness. The profile was eppler 193 or 222 or something. Works perfectly with the same stabilizer. I think surface area, thickness and prof...

I need to buy a race foil with a plate mount

I have been riding free ride foils for a few years but am now ready to step up and start racing. So far Levitaz and Moses are on the list, have I missed any other manufacturers? Any opinions on performance, ease of use and quality from current owners of these foils? Unfortunately there are none in m...

Re: Tips for Ragnarok?

Current conditions on the vidda. Regarding the shovel, beacon etc, I would not bother. It is easy to avoid any dodgy looking slopes or windlips

Re: Foil Review: Banga BF016WA001 Race Foil

Hi Gunnar,

Looks like the mast to fuse connection is different to other foils. Are the bolts running up into anchors inside the bottom of the mast? How stiff is this connection and would you worry about hitting the bottom with it?

Thanks, Rob

Re: Tips for Ragnarok?

Done it 3 times but can't make it this year. Redbull prefers to run the race on a sunny day so usually that means lighter wind although windy and sunny is possible but less probable. Spring snow that time of year but still possible to have some freshies. If it is light some line extensions for the 1...

Re: Which foil kite for light wind foiling

For free ride on a hydrofoil in light winds a performance foil kite in the 10 to 12m range is all you will need. Sonic 1 11m works great.
