Well the popular opinion seems to be to use it as a ramp and go for it :driving:
Small story here....
Out in Oregon, Columbia River, runnin a 15.5 Glastron Carlson with a 235 Evinrude (the 135 it came with wasn't big enough). Thought I was Bond, James Bond......
Tollycraft Yacht Fisherman, think they were 72', cruising up the river max cruise. Those things put up the smoothest 5' wall of water you ever saw. Somewhere in the mid to upper 70's, goosed it right at the launch point, first wave about 20' or so off the stern of the Tolly........
Passed him looking down at the guy driving on the bridge

. Can't believe we lived and the boat actually, mostly, survived. The guy with me never got in a boat again with me.....:sifone:
Landed stern first by the way, broke both seats and the foot rest, the boat did stay right side up, but when we hit the motor was completely under for a bit then popped out, jumped, and went over forward.
