A visit to Tradline at Braunstone produced a new button vee, this time not fancy. They produced the last fender. I note that the new fender is somewhat deeper that the original, even taking into account the compression, and that the core is rubber not rope as the last fender. Maybe the rubber core will resist distortion a bit better than rope. I remember Colin Jones at the fender-making class I attended at Stoke Bruerne Museum in the 1990s stressing the importance of the core but he was not keen on rubber. However, we had a rubber-cored front fender on our last boat and it lasted over 10 years.
