My intention was that the rudder have a stainless steel strap over the top, through-bolted to the rudder. The tiller is pushed into the front of the strap and secured with a pin, so that it can be quickly removed to clear space when at anchor.
An alternative is to bolt the stainless strap to the tiller, leave out the forward bolt that secures it to the rudder and leave the aft bolt a bit loose. Round off the aft top corner of the rudder with the centre of the bolt as the centre for the radius. Now the tiller can be lifted up to get it out of the way.
