I just finished my new semi balanced rudder. I must say it looks pretty good and I had fun building it. My question is, will it change my rating at all? It seems to have about the same surface area as the old rudder. I do a little racing and really don't want any problems from the boats I leave behid:-)

Jim - that's an interesting question! Installing an upgraded rudder from the factory does not change a PHRF rating and an existing rudder can be faired without penalty. However, as yours is custom built I would suggest that you give the specs, together with the factory specs of their rudder to the PHRF Committee and allow them to make a decision. IMHO it should not make a difference if the surface areas are the same..

Like many of us, my original rudder is beginning to split, and I have been thinking about building a replacement, as you have done. I have seen drawings of the new rudder design, but haven't seen a good explanation of the construction process. If you could describe your methods and offer some suggestions, it would be helpful. One of the things that puzzles me is how you shape the trailing edge of the rudder, thinning it down from the thickness of the plywood core to the thin trailing edge.

FYI:

Catalina Direct recently reduced the price of a replacement balanced rudder. I believe it was $443.00 plus S/H.

It was not that hard to build all though I do have a little fiberglassing experience. I used 2 pieces of 3/4 marine plywood and epoxyed them together using a double mat between. After determining how far back to make the taper , Igot out the chainsaw. I cut 90 degrees to the trailing edge and made several cuts close together. Then using a very sharp axe, chipped away as much wood as possible. Using a disk sander I faired the rest of the way. Then epoxyed the edges first and the sides next. The hardest part , I thought, is fairing. That is really time comsuming, and I didn't get mine prefect , I wish now I would have spent more time. I've never used epoxy before and fell in love with the stuff. I don't care if I ever see another gallon of polyester resin again. I certainly saved some money doing it myself and enjoy the time it took.
