Simple math...

It also seems like there's not a whole lot of pressure added onto the teak. There's a couple guys that bootyfabbed a setup over on the Malibu forum, where they have have the paddle clamped to the teak. One Mastercraft guy reported maybe 80-100kg of force on the paddle itself. Makes sense since 5psi = 20mph, 11 psi = 30mph, 19 psi = 40mph, 30 psi = 50mph (Taken from a Airguide Speedometer writeup). So We'll say that the PSI at 10mph is 3psi. A paddle that is 10X20 at a 45 degree angle will roughly have 100square inches of surface area, equaling 300lbs of force. They're not at a 45 degree angle, more like 20 degrees, so the force is probably somewhere around 150lbs. The teak and transom is more than capable of holding this
