We did our PB2 over Christmas with David Leutchford at 5Star Marine in the The Hamble. The conditions in Southampton Water were "lively" with a full gale 8 gusting 10 blowing. We got chance to do some rough water handling & definitely learned a few things, even after 25+ years of boating (I've never had any "formal" practical training, just picked it up as I went along. I did the BSAC boat handling course 20 odd years ago but that was in a Squidgy or SIB as they are now known
) One of the most useful things David taught us, was to put the power ON when coming of a wave in a head sea, my natural reaction has always been to come off the power. Coming off the power allows the boat to flop/slam into the trough; keeping the power on, keeps the boat "taught" & drives it up the face of the next wave. It took a bit of "re-learning" but once you get the hang of it, it makes for a much comfier & faster ride.
You can teach an old dog new tricks
PS David/5Star marine is highly recommended if anyone is considering any PB training.
