The stock rudder for my Epic V10 surfski catches kelp and weeds so I decided to build my own "weedless" rudder as a replacement. Here's how I went about it. . .
Step 1: Materials
This is the second time I've made a surfski rudder. The first time I used marine plywood but this time I decided to use balsa since I thought it would be easier to shape and I would be glassing the outside for strength anyway.
The stock rudder is about 5/8 inch thick with a 3/8 inch diameter shaft. I bought a piece of 3/8 inch stainless steel rod from a metal supply store and balsa from a hobby shop. Two part epoxy resin and 4 oz. fiberglass cloth were left over from another boat building project so I used that.
