guys I swung by goodtime today to check out a one design they have in the racks for sale.
it's a retractable centreboard model. centre board had a very small chip out of the bottom of it.
at a guess I'd say early retractable centreboard model, possibly first version after the original. has the dark red clear fin that looked mint and the screw down uni on the sliding track.
mast looked to be original didn't look at it removed from sail. sail was original and of course has delam so will need replacing at some point probably soonish.
board looked to be in very good condition and I'd say not used much but I didn't weigh it so hard to tell if it's ever had a small nic etc.
coupla hundred..................

perfect one design to get you on the water and racing or cruising with the family.
