Yeh I've got a nice little scar on the side of my face from a leggy recoil when one of the side fins stabed me in the cheek.It was in about 4-5 foot onshore ****,I'd actually taken the paddle home and was riding the SUP as a prone board just to see what it could do.It was a big wave long board leggy probably about 9' long.But I've used the same leggy on a diffrent longer and narrower board and it was fine in bigger surf which leads me to think that weight,volume and shape play a big part.What I mean is some boards want to come back and some don't the ones that don't when they do,do it in a hurry.
