Wouter,
Due to your additional input I have a much better understanding of your trap technique; I have to wait for the water to warm before I can tell you how it works! And thanks for telling me you do it differently on your skiff than on your cat... now I don't feel quite so confused why I couldn't translate the technique more closely. I also had to initiate trapping out more vertically on my monohull but thought this was inexperience (or lack of guts)... maybe it was just good (or lucky) balance instinct.
