Needed a centre board for merlin project 
as soon as possible , grp or cedar sheathed would be great . 07825773360 Martin 

More info would be useful.
 
Design and builder.
 
 

There were a few boards on eBay recently.. 

Hi Brian , could you please ring again concerning centreboard for sale , lost your contact , centre board to fit 2945 infidel design  , but need something bit newer in weight and build ? 

Boards vary enormously in thickness, length and shape.
 
I doubt you will find a remotely modern board that will fit in your case. You MAY get lucky with an NSM II era board and this may be an improvement over the existing foil. But you do need to do some homework first to make sure that any prospective purchase will physically fit.
 
You need to watch the pivot bolt position too as this varies both between designs (even from the same builder) and builders. 

Thanks for the info , I will checK all the sizes before fitting one !!!!
