My experience
I installed a leather wheel cover several years ago. I think it was the kit from Boatleather. It was the padded version that contains self adhesive foam tape that goes on first. It also included the center marker, which is a 2-inch leather strip that indicates if the rudder is on center (or in the case of the C310, also at extreme port or starboard position.) We got "Pre-punched leather, waxed polyester thread, double stick tape, two sail makers' needles and stitching instructions." in the kit. Grey looks real good on our 310.Installation was a bit of an adventure_from my 2001' vacation cruise;"That afternoon I decided to install the padded leather wheel cover that I received as a gift from the sales person that sold me the boat. It arrived the day before we left. It's a long story, but I got it after using guilt to get him to come through on sort of a broken promise. I thought it would be about a two hour job at most, but I soon found out I am no seamstress. I started about 5:00pm. Barb and the people in the boats around us were a little bit amused, watching me take a few stitches, then taking them out again. It was literally two inches forward and an inch and a half back. At about 7:00pm I figured I'd better take Barb into town for some dinner. I had some really forgettable fish and chips, then it was back to the boat and my project. I was starting to get the hang of it, but darkness came at about 9:30pm. I had a vision of having to motor off in the morning with the cover half-installed and tangling up on the steering pedestal. Maybe I could secure it temporarily with some rigging tape? I also thought about getting the flashlights out to work into the night, but my fingers were aching, so I decided to call it a day. I was up early to get that cover finished. By this time it was going very fast, and I was getting good! I had made a few mistakes the previous day, and I had a brief wish that I could undo it and start over. But I finished by about 10:00AM and thankfully got to leave. " I don't mean to discourage anyone, but it took me a while to get the hang of the stitching instructions.
