Sailing at the Dart 18 Euros in 1986 in Katwijk Aan Zee; Massive surf, waves were so big, sailing up wind you had the impression you were doing really well as you could only see a few boats; problem was that if you were at the top of a wave, you could see the other boats on top of waves, if you were at the bottom, you could see nothing. Wid at the bottom was about 15 kts; 30 on the wave tops.
In the penultimate race my crew broke his arm and I sailed inthru the surf and 100m up the beach.
I was 18.
I'll never forget it.
