Vincent Valkenaers did 53.06 knots over 2 seconds at West Kirby a few days ago, according to www.gps-speedsurfing.com/default.aspx?mnu=user&val=315031&uid=6135. I think that was in the same big storm that stopped train service in many European countries for a few days.
Pretty impressive, a new spot record and faster than any non-Luderitz session on the GPSTC. Hans Kreisel did 50.86 knots (www.gps-speedsurfing.com/default.aspx?mnu=user&val=314967&uid=2042).
