Jean-Yves Salaun of La Flotte, France built this 3-windsurfer triscaph, "Deltamaran."
He has experimented with different sails, typically of the "crab-claw"
variety shown here.

Jean Hurtado brought 2 of his creations Hurlam and Drac shown here is Hurlam. Its
main feature is its monohull, a NACRA 5.9 I believe, with a Tee-shaped framework
with floatation pods on the extremities of the Tee. Here's another
pic of the boat.
Motive power is supplied by a rogallo type sail across the top of the
T. Jean's explanation of how this is tacked is better than mine but basically the
boat is rolled through 90 degrees to set the sail on the other tack. A lrage beautifully
made steering wheel is provided to assist the manoeuvre and Jean nimbly leaps from
one seat to the other protected by a splendid riding hat. He needs appreciable quantities
of wind which were not here this week accounting for his best speed of 2.38 Knots

Tony Blofeld designed "Speedwing", a biplane catamaran with double unstayed
windsurfer rig. Although very wide, Speedwing is designed to weigh the same as its
pilot, to give an all-up weight the same as two windsurfers. Additional photos of
Speed Wing, in 1997.

AYRS Director Fred Ball, Surrey on "Tri-Fly", built by Tony Blofeld. Fred
fitted new floats in 1996 and continues to re-engineer the boat.

Vari Scari was sailed by Alan Blundell this variable geometry trimaran comes back
each year with minor improvements and one day will show its potential - but not this
year. Alan's best speed of 5.01 knots reflected the weather conditions.
Tacking involves altering the geometry so that there the front float moves
to leeward, and the pilot jumps from one rear board to the other.
