According to WSSRC the 24 hour distance outright is taken by:

2007 "Groupama 3" 103 ft Tri, Franck Cammas FRA, 794nm, 33.08 kts

The best windsurfdistance records over 24 hours is less than 220nm, 9kts. And it is not even ratified official... Maybe it is time to try some distance sailing. OK the chance of beating the outright records isn't there...

If I would speak for myself my session speed is about 16 kts average, highest 1-hourrecord is about 23 kts. I would say that it should be possible to break at least the 300nm...

Only the right equipment/ wind/ good support is the key

But One RECORD is really impressive

1854 "Champion of the Sea" 225ft Clipper, USA, 467nm. 19.46kts


Captain Alexander Newlands, was the fastest for more than a age.

I would love that one to beat, the record is 154 years old. I mean in 154 years of evolution could it be possible to break it on a windsurfer?? Ok as a windsurfer it is impossible to sail 24h. If you do 4 sessions of 5.5 hours and 0.5 hour brake... You have to do an average sailspeed of 21.22kts= 39,31 kmh

My common sense tells me there is a chance, but don't think it will be easy. Everything has to be right. Human condition & Weather & Gear have all to be right for 24h... Is it windy on Full Moon? haha
