I wonder if they could go faster on ice ?
Flatter surface, better sideways grip and less friction.
Well, that sent me down a rabbit hole. Allegedly, the mark was set 90 years ago by this boat, Debutante, at about 231 km/h but given the timing methods and technology of the time, there's a lot of doubt. But there still are supporters, too. I have no stake in this but kind of surprised I can't (quickly) find anyone posting gps tracks of their iceboat.

"Letters from Readers:
I fully acknowledge Richard Jenkins land speed record at Lake Ivanpah of 109+ knots, but question 'the fastest wind powered man on earth' as ice boats have gone much faster with the E-Skeeter during fleet racing and not even going for a record.
These iceboats have been radar measured and course race clocked several times at 120mph/190kph. These boats commonly race at 80mph/130kph to 100mph/160kph in 18-20knot breezes and over 25knots will reach and probabaly more, 190kph so why are the ice boat speeds always ignored and not recognized?
If you doubt me then please contact the great Buddy Melges, gold and bronze medalist, and Americas Cup winner at Zenda, Wisconsin next to Lake Geneva where these speeds in ice boat racing are commonly achieved.
Regards,
Peter Harken
Editor's Comment: Don't doubt you. Good point!

> Message: As Peter Harken already mentioned, today's ice boats commonly exceed this speed. But according to 'Boating Facts and Feats' (by Peter Johnson published 1976), the fastest official ice boat speed was recorded on Lake Winnebags, Wisconsin in 1938 by sailor John D. Buckstaff. It was a stellar 143 mph! "
