I'm excited to have purchased what I believe to be an Annapolis Discoverer 17. It needs some TLC, but will be great to teach my 5 kids to sail on and has most of the original parts, but I cant sail it until I replace the tiller arm. It has a drop down fiber glass rudder, but the wood arm looks to be too weathered to last under stress. Anyone know where to get an arm that will fit this?
