I live on Lake Michigan and had to put rip-rap in last year to protect the shoreline from erosion due to high water. I have no problem pulling my Sunfish over the beach but I can’t figure out how to get it over the rip-rap. I’m thinking of a simple ramp or rails covered with carpet with a winch at top. The ramp or rails would have to be long enough to get over an 8 foot bank but I have no idea how to calculate the length for a gentle slope. Also, I can manage simple construction bit can’t construct anything fancy. Any ideas?
