Re: Ketos: Is one-bolt mount strong enough?

I think the key to KF box including ketos and others is to have a strong reinforcement of the connection all the way through the board and use a big, thick washer -40mm or so. I don't own such a foil but have some envy of their good looks, weight and performance. Since I am good at discovering sandb...

Re: Another DIY foil

About the washout/reduced AOA at tips: Since the foil is almost always ridden heeled a bit to windward, you really don't want your lift distribution to be unbalanced when the inevitable tip stall/breach/ventilation happens. It could possibly cause a capsize/hinge motion crash, the kind that send the...

Re: Converting surf board

I just meant like what a previous poster “mopman” did to mount his foil. Looks like nut inserts embedded in plastic/resin. If the board is heavy glassed, a few more layers of patches and inserts mounted in strong resin/milled fiber columns that go all the way from bottom skin to deck should work. Wh...

Re: Converting surf board

Now I get it, tiny surfboard in "golf bag" type of bag must be what you are doing. Sounds like your board is a candidate for a mopman style conversion. I would love to see pictures of the board or brand/model etc. By the way in case anybody doens't know this, international flight board bags are usua...

Re: Why pro-riders move the hip forwards?

Science: it's because racing kite hydrofoils causes previously silent windsurfing genes to be expressed ;)

Re: Converting surf board

If the board is a heavy/strong one it may work, get someone with experience to do it. Will need heavy stringers and/or lots of glass patches plus through holes or inserts. If board is light it will probably not feel as good and have a risk of breaking. I have a light surfboard I kite with some but w...

Re: Have lei kites gotten any better in the last 6 years?

In my daydreaming and pencil on back of serviette scribblings I've often pondered on a sort of twin skin foil lei hybrid, to give the foil platform more protection against wind sheer and shifts. Probably be a bit too expensive for mainstream use but could possibly find favour in race foiling. I nea...

Re: Simmons Planing Hull

@ Norby
I think it’s a great idea and not far from some soft boards you used to post in pictures/videos 👍🏻
Simmons greenough tomo cole etc., so many good designs around a higher aspect ratio planing surface....
