Now using foil on 2009 RRD X-Fire 122L and as a 'winged keel' on 1990s Speed 250L race board.

I just needed to figure out how to use a 2017 foil designed for a deep Tuttle box on a 2009 board with a standard (shallow) Tuttle box that wasn't designed to take the load of a foil.

The solution* (*you can just buy a board with deep Tuttle box and get foiling) is to redistribute the load away from the standard Tuttle box and create a load-bearing 'sandwich' - to spread the load between the top (deck) and bottom of the board.

This should work for all foils with a flange - such as Starboard GT, Slingshot & Fanatic. It's a new option for people with older boards still in great condition and perfect for foiling, but limited by having a standard Tuttle box.

Note: It won't work on foils without a flange - such as Neil Pryde Alu Flight or Starboard racing foils.

This 'sandwich' method also works well with longboards with open centreboard boxes such as the 25-30 year old Speed 250L race board from the 1990s. You just need 150mm long M6 bolts.

just wondering if anyone has used these foils with thier slalom gear with any success?

i tried a set of these in my JP 85 wide slalom board and struggled to get them to fly the board like I can with the RS Flight AL foils. I kept moving my mast track back til the foot was almost out of the track but the board still kept wanting to touch the water constantly. I had the rear stabiliser in the highest lift position as well. Any thoughts?

Cheers. :)
