We were one of the boats that did go out, and it indeed looks like the surf was smaller compared to the pictures from the worrell, however, the wind was 5bf straight onshore, and waves were coming in every couple of seconds, so there was no time at all to pick up any speed between being hit by the first wave and being put back on the beach by the next one (and breaking your rudders or mast).
Luckily our good old nacra 6.0 is not the lightest boat around and we were able to punch through with relatively few hits and managed to keep going, but we saw many lightweight f18, inter 18, tigers and so on being thrown over.
btw, the next day was even harder getting through, just slightly smaller surf, but no wind at all...

oh and for the speed interested among us:
round texel is about 60nm, new record time is 2.11hrs, that's an average of almost 27.7nm/hr! (that's fast! am I mistaking the distance?)
