From kitesurfing records to a hydro-foil update

A new foil, a new idea – and a satisfactory 50 knots achieved in the trial runs.

Foils are getting faster and faster

Walvis Bay speed sailing course is was the setting and was where a 50 knot peak speed was achieved on the following day. Paul Larsen was very happy with how well the new foils got up to speed in only moderate conditions i.e. 22-25 knots. In the video you can see that the boat was riding quite low at the back with the rear float often in contact with the water. This means that there is a lot more main foil in the water than is necessary. This creates a lot of drag. The team gathered a great deal of very useful data and will now try and trim the boat higher at the back. The target is 60 knots and above.

There is a fair amount of expensive technology in the …. boat ? ….. but it is very impressive. However, between the two it is still the kitesurfer which holds the record for the fastest on water. A few more tweaks might take the foil out front… perhaps I’m a bit of a philistine, but it’s not really the same thing is it?
