Yep i dunked a dual line once not realising there would be a downdraft on the backside of a wave ''

I got it out with patience, sort of like catching a 30 lb fish on a 5 lb leader, steady tension on the line, take advantage of anytime the resistance drops but keep the tension below the breakage point. I tend to fly a bit higher over the waves now, no wingtip drags.
