35 foot waves would be interesting. Years ago, I was part of a scuba dive / rescue team in Petoskey. We got a call and took the boat out for a capsized vessal. It was a nice sunny day but very windy. Anyway, there were three of us sitting in the bow of the boat in our wetsuits ready to go in the water. The waves were 10 to 15 ft. Every time the boat would hit the peak of a wave, it felt like we were flying, and then it would come down and we would basically be submerged for a second when we hit the low spot.
Point is, we were having fun as it was nice and warm and we were dressed to get wet anyway, but I couldn't imagine being in waves easily double the ones I was in. That would be pretty insane.
