What boat is it?
Jeff -Which boat do you have? Is it a Rhodes 19 or a Mariner? What is the board made of?To my knowledge, all O'day built Rhodes 19's and Mariners had 130 pound steel centerboards controlled with wire. It is possible that your centerboard pennant broke or was in danger of breaking and that the owner at the time replaced it with rope. Its also possible O'day did it originally on some (most?) boats. On your boat I'd want to check out the pennant attachment point, but I'm not sure I would concerned with the material of the line. As long as it isn't chaffing through and isn't binding, you should be ok.Justin - O'day Owners' Web
