I am fleet captain at a yacht club with a great 20 ft wide ramp and a jr. sailing program. I pressure wash our ramp three times a summer to keep the kids from slipping while launching boats. It is quick, easy, enviromentally effective, and works really well. I can do a 20 x 50 ramp in less than an hour.
But how is that going to help Mary's problem when the slippery conditions are on the submerged portion of the ramp? It's not tidal and so the pressure washer wouldn't work would it? Have you tried using it below the waterline?
