Apr 22, 2007 - Five myths in the first four minutes! One ghastly myth was the idea that a heavy fin creates drag, weight actually creates drive. Another classic myth is the idea that the sidefins pull you into the face of the wave when in fact they have the opposite effect due to toe in. The worst one was the idea that he's "about covered it". . . . nothing could be further from the truth ! To put it bluntly, it's mostly nonsense, but will pass for knowledge with most people. :(

Oct 3, 2008 - Yours is a strange attitude, saying shut up and swallow the BS ! What's the point in a tutorial that is full of misinformation?

Jan 31, 2009 - Cheers Roy, it's good to have a second opinion. Shaper Directs' concept of where high and low pressure are relative the foil seems backwards to me. The sharp edge of the foil catches water transfering it to the side of the soft edge.That equals high pressure on the soft side, right?He may have a point for surfing barrels where the water is running up the face fast and you're tryin not to go up with it. But lets face it most waves you have all three fins in the water.

Sep 8, 2009 - Hi Shapers Direct, I enjoyed your breif tutorial. Your basic terminology reflects industry use and your breif of how a fin works is generally pretty right. For Pattie Cannons comment, The tutorial is correct, the rounded side of the fin is the low pressure side. This is based on Bernoulli's Theory, Its counter-intuitive but 100% true. The central fin works both ways, but less efficiently because of its symmetrical shape. Hope this helps to clear up the confusion. Mike Batt
