To answer all those who asked "why put in all the Pitch Poles" You've all really answered the question already, it gets people talking and makes others interested. The video was produced for a boat show and most of the people who saw the "action" watched the whole video again to see it a second time. Sure these were particularly violent (as well as doing the editing for this video, I was helming #74) but I believe it adds to the excitement of sailing catamarans. Most people who sail have some craving for adrenaline.
In reality the Spitfire doesn't pitch pole very often, it has quite a lot of volume in the nose, however we were sailing in extreme conditions. Although you can't see it on the video, it was gusting from 10knots to over 30knots in split seconds and the wind was shifting 90 degrees at times. The water was extremely flat because we were sailing up and down narrow shipping waters where we could film from a bridge.
