Does anyone know where I might be able to locate a new base to a stanchion?
I bought some a couple of years ago from Hunter Boats, but sadly the holes did not quite line up I don’t know if dimensions had actually changed or it was just poor quality control during manufacture (N.B. Hunters were very good with a rapid refund). I then found some second hand ones in the famous Deacon’s Barge on the River Hamble which did the job fine – I think these were a very common part during the period and should be easily sourced from a boat jumble.
The correct fittings can be obtained from Seamark Nunn
Get the JHYS7157B base as this is the on with 70mm centres
