This is a rope fender, or more aptly a waste rope fender that I made from some dog leash left overs.It was fairly common practice "back in the day" to utilize old rope to make boat fenders. In this case I am using 1/2" poly-prop lobster pot warp line. The fender is probably only big enough to be effective on a dinghy, but it is is certainly something that could scale up. I also think in this day and age I'd stay away from mooring a fancy expensive yacht with a rope fender as I would be concerned about scratching the paint. The fenders sure can look nice though.
The project was adapted from the book The Marlinspike Sailor by Hervey Garrett Smith. It has a rope core crown wrapped in the 6 strands that come from a looped piece of 3 strand rope. At the bottom the strands are walled back up into the fender. I also whipped the loop with a 4 lead by 3 bight turks head. Could probably be a little neater, but the poly pro is a bear to work with and keep tight. A simple and fun little project. Thanks.
