Why accelerate from the water to the beach? Looked like he was still way to fast?
Might have been slower if had lost all lift at the landing point instead of just starting some deceleration??
Wasn't in the seat so hard to say!! Don't think I would waterski to a ledge tho!!
I always used the water to get slow and then right before getting to dry ground dumping flaps and sticking the tailwheel in the water to get slowed down a little more.
Once the Mains were on the dry ground he could have used way more brake and power to keep the tail down and got stopped a lot more quickly.
Granted it has been a couple of years since I did this fairly regularly so I might be all wet!!
