Ever heard of one of these?

I have this morning taken possession of a huge pile of old boating magazines, and naturally, during the 'sort out' started to flick through them.

There is, in a 1970 Practical Boat Owner, and advert offering a Century Plus, which is described as being fitted with a 'Gydacraft' rudder.

Has anyone seen one? Or got one? Or a picture of one?

That was in the third magazine I picked up, I have another thirty odd years to go...
