Hi Stavros,
It wasn't so much the size of the waves that got most boats, it was that there was no direction from which they were coming at you. The far end of the lake is just past the line of booms at the top of the pic. and flat calm. The walkway edge is from where the pic. was taken and the waves were coming down the lake which was ok until they hit the concrete walkway and then echoed them back at you. The water just lifted without any frequency or rythmn to it so no matter which way you faced could you get your bows turned into it to ride them. The day before, saturday, was flat calm and no breeze and the water was like glass which was just as well as we did tug towing, now that could have been interesting if the weather had of been the same as the sunday!
Paul.
