From talking to the guys at the show i understand that Jo richards was pumping the t foil on the waves in some conditions and gaining from it. So the system has to be able to take a lot of punishment.  I'm not sure how that is viewed under rule 42.

The problem with the design used on the N12 is that the loads on the bottom pintle are significantly higher than those on the top pintle.

If you do not have a gantry then using the bottom of the boat to support the massive lump of metal needed to get it to work is feasible but if you are going to have a gantry then there are many much more structurally elegant design solutions.

I have a 2 Rudders with lifting foils for sale:

A nearly new development set £500, and new latest design £700.
Pre-preg carbon, corecell foam, from Aluminium CNC tooling

Spring clear out - refer them on a boat going fast than gathering dust.

New users can not upload attachments or post live links for the first five posts, to stop some of the unmentional pictures that have been put up by spammers.

As you said he could email pictures.

From the pictures they appear to be designed for a pivoting rudder stock which is pinned down in the vertical position.
There is nothing stopping someone from building a stock for these foils. they do look really nice.
