thats true, i like to do a bit of every thing, nothing beats blistering speed sailing

or i quite enjoy freestyle

, the waist harness i find is great for freestyle and speed, but as elmo said you get that feeling of almost/actually being flung over the bar

. So the seat gives you more security and downward pressure on the mast, while a waist harness would deliver power and agility because the mast is more upright and you can lean a lot further forward(early planing) please correct me
