Construction continues on the new foils for the 05-06 season. Faced with the choice of a three piece “tee” mould, or moulding individual sections; we have decided to make the sections individually and bolt them together with some serious We are following this approach for a couple of reasons.

• It appears that almost every set of foils made to date has had some form of failure at the tee joint, so we are going to put some serious reinforcement in the sections and use several 3/16 stainless bolts to connect the foils together.
• We can easily try different foils on the same centerboard
• We are going to use the same sections on another hydrofoil project that involves a Hobie 18 …

The photo above shows one of the finished mold halves, and the male plug. We have used chopped strand mat instead of just making a screeded bog mould because of the large number of sections we will be making.

This is a closeup of the end of the top half of the NACA 63412 section with a 120mm cord. Thanks to John Illet for full disclosure of the section shapes and sizes he is using, removing the need for a ton of guesswork.
