Can anyone help I am looking at getting a lifting rudder but can't seem to find who to approach to get a new one. Any ideas?

Winder Boats would be a good bet, as would Kevin Driver, Linton Jenkins, Lawrie Smart or Alan Jackson.

Deatails in the suppliers section linked below.

and CPC Boatworks  :-)

Do they sell direct as going through a local retailer a lifter is not cheap I asked and was quoted over £500 complete. 3496 will have to wait a little longer for her new rudder.

Another vote for Chris Clapp (CPC) - he charges about £250 for a carbon sheathed lifting wood blade (painted), a little more if you want a clear finish to show off the carbon.  

Chris can also do a flashy carbon stock to match, or of course Tony at Sailsport can help with a standard ally stock ;)
