That Burvill guy has gone and built a double surface sail. It has only been trialed once so far in a very light breeze of 5-8 knots. The foils were on but there was not enough wind to get it flying. It was difficult to analyze or get any feel for it as there just wasn't enough wind.

To be a bit more specific about the bits and pieces. It is all a light grade of monofilm with minimal reinforcing. There are 5 battens (which is really 10 battens) The top one is actually the head it'self. The mast is 65mm x 1.2mm carbon (windrush spar) and weighs just under 2kg, it only bends about 80mm.

Rigging this crazy beast can be quite a task.

It works like this, even though there is an adjustable mast spanner, the mast can be pretty much be left at centre. With the battens fixed at each side of the mast, as you sheet out, the windward side is pulled flat while camber is pushed into the leeward side. The wider you sheet the deeper it gets.

Not much else happening with sailing. Garth has been living it up in Greece and Turkey for past several months and will be home late November. Peter Kovesi is in NZ and will be back late December.

Oh! also Alan Punch in Bunbury has bought some of my carbon hydrofoil section for his moth. Soon we can have a hydrofoil fleet start!
