Rudders and Engine replacement

Following questions mainly from the RYYC fleet, the JR yard says "You should add the 2 cylinder Beta 12 hp to the list of acceptable engines, which is the one we recommend at the yard".
Rudders, to dispel the myths about rudders, "everyone needs to know that only the first 50 or so rudders were made of wood and simply painted (not sheathed in any way); subsequent rudders were made of grp with a foam filling.  The weights did not vary significantly between the two types of rudder".

 Jeremy has just told me that he still has the original rudder mould, so anyone needing a new rudder would do well to have one made at the yard.
