I can tell you that boats penetrate at least their whole length from the ramp we built.
Perfect pencil landings are very hard to do intentionally when you have a kicker at the bottom of the ramp but at least one guy in the videos on this site managed to do it twice. He smacked his sunglasses of his face on the second go and decided not to try it ever again.
Matter of fact I haven’t seen him in a kayak since.
A person could do serious damage to themself with this ramp. Back flips and other similar moves that could result in flat landings are very hard on the back.
Male anatomy also can be sensitive to flat landings, consider that certain parts don’t stop moving just because the boat does.
I for one have no desire to subject my back, my nuts or my dignity to another ride on the Boatwerks Ramp.
