Well what a plesant suprise to find so many people enjoying their RL's, We have been based in Port Stephens for many years, with the Myall Lakes nearby it is just magic, but thats another story.
I am looking to replace the Rudder Blade on our much loved RL34, we have been fighting a loosing battle with osmosis in the rudder for many years and I have concerns about its long term integrity. The Rudder is swing mounted on a cast tiller assembly. Does anyone know where I could buy a new one !! :-), or arrange to have one made
Why not have a go at making one yourself. Use ply or the proper foam core and just build up the layers with glass and resin. It is a very easy shape to reproduce and I don't believe a true aerofoil shape is really required. Anyway you have one to copy. A good chandlery can advise you what glass to use and how many layers you will need. It is also worth contacting the resin manufacturers - they can be very helpful. They also have brochures and probably web pages to describe the process step-by-step. The bigger boat shows always have stands with retailers of foam core, resin and glass.
Heed the safety warnings though.
