Hi Stuart,
I had seen your emergency rudder on the PSSA site, and I wanted to make the same!Too late!!!.The starboard locker is the good place for it.To take off the broken rudder blade head at the sea, is not impossible. I did that in night with a rough sea,laid down on my stomach in the cockpit with the helmsman seat off ( but it is more easy for me because I have a tiller helm). A wing nut with a little hole for a little string, another string for the other axis side, and another axis for security on board( I had!)because you can lose this pieces when you have a wave. To put an sea anchor would give the operation easier. When I put the pliwood emergency rudder in the shaking mooring ( at Hugh town St Mary Scilly), I had to put the blade vertically in the air by the mainsail halyard with a screw driver to find the blade hole inside the stainless steel head. .
The emergency rudder blade could be made in a thiner true wood, with only two pliwood pieces to enlarge the head inside the stainless steel part.
I have contacted Phil Milanes for a new blade. He cannot have the blade drawing from Fosdyke marine( which has the hull mouding and has never received rudder moulding).In the same time I am looking for a broken carbone centerboard ( from vendee globe racing boats or big trimarans).
The original rudder blade is too weak at the neck part (between the head and the body) Inside you have a ramin wood with a thick filler part around.The rudder area is important, and the Parker 325 is not a dinghy. The time also gives the rudder blade weaker.
That will be better, if the PSSA could have an address where the different Parker boat items could be found or made.
Best regards.
