Following capsize last night (storm force winds, inexperienced crew, tidal wave, whirlwind, swerving to avoid oil tanker, attack by Great White - oh alright, we fell over) tiller and both transom flaps gorn.  

I can sort the flaps.  Any suggestions for a source for a replacement tiller?  All the web is throwing up is extensions and accessories.  The original fitting is a slide-on bracket.  Pleeease don't tell me I'm going to have to replace the whole foil.

Try your insurance company - get a new one

no Its time to use that old ali spini pole
cut to length, screw it to the top of the rudder, cover in carbon or fiber glass matt, paint, and Bob's you uncle.

Carbon on alluminum :/

I have a spare 6ft ally pole if you want it.

is the stock an IYE,if so I have a complete stock,tiller and extension which might get you out of trouble.
where are you situated?  Its cheap by the way!
