Guess the Speed

[lyc]

What sort of speed would Kojiro Shiraishi be surfing down these Waves in the Southern Ocean during the Velux 5 Oceans?

 

[Will_M]

close to 20kts..

 

[Largslout]

Mach 3

30knots? Doesn't look too bad really? Big waves but not "raging".

 

[zefender]

Well the first photo in the set mentions 18kts, so I guess it must be about that really.

Alex Thompson recorded 30 knots before he keeled over so I suppose Shiraishi could be dong something similar but from the pix I would think 20 or even less.
