It's a pity the photos can't do justice to the first couple of days. There were some awesome sights at the gybe mark (the gybe mark was closest to the shore).
I remember vividly sitting at the top of one wave, with the gybe mark sitting at the top of the next wave but I was still a long way from the mark (I would guess about 15 to 20 boatlengths) and there was just this huge hole (like a crater) between us.
Peter Nikitin had an interesting time gybing around that mark while the 4 metre wave actually broke right behind him. A few spectators on other boats watched this and just waited for the crunch which, fortunately for Peter, never came.
The amazing thing was that even when the wind got really light (4 knots or less) we could still make forward progress against these waves, going upwind.
