If my memory is correct, only one F18 boat has sailed the W1000: Team Netherlands, Hobie Tiger, 1999? They used the jib.
and the boat ended up in pieces!!
I recall they broke the mast coming into the demolition derby that was the Hatteras checkpoint that year. They had no spare mast and had to retire. This was at a point in time before HC USA began importing the Tiger from Europe.
BTW I think the correct team name was Team Holland and the spin was launched from a tramp bag (pre-snuffer).
