you talking a 13 footer, or a 17 footer, or bigger?
I have walked down that ramp..it isnt that bad, It might not be paved very far into the water..... the 13 footer is a small boat..... the guys there pull boats twice as big up into the trees , 40 feet from the water all the time. You should be able to winch a whaler up....
you got a tilt trailer or not?
unless a recent storm made it worse
actually I found this picture
doesnt look to good in this shot, but i walked down it to wash my feet of sand before i put my shoes back on and the ashfault seemed to go into the water...as i recall......
might ask a local to go check .
