Maybe you can apply rope around the boat and floorboard, to improve with some partial pieces of plastic foil and cork bumper ?;
I had bought Sevylor K105 in 1976, (sell in 1987), (and similar Orion 3100 in 1995), this boats is suitable for sand beach and lagoon because
this boat are big and light ( storm wind is very danger).

I haven't owned a Sevylor but I have owned a SeaEagle, and the boat boot is a good idea. Don't drag your boat at all, I did and paid for it dearly.I was careful where I dragged it, but it didn't matter. I wish sea eagle had a boot, as i am buying another one. Unless, you took it to a canvas place and they could custome make one for you, out of some kind of material. The same place that makes boat covers, RVcovers, etc. Sea Eagle has a 2 wheel dolly that you can transport, and some boat places like Cabella's has a dolly for boats that you could probably use to transport your boat to the water. They are about $75.00. I'm sure the custome made cover from the fabric shop would be more. better go, wife needs the phone line.
