hi bob
thanks for reply
it would be useful to see photos
could you give me the exact position of rowlocks?
interesting that Ian Porter would not be drawn on measurements as there is supposed to be a wooden block built in IF you were going to mount the rowlocks on the side deck. He advised finding them by tapping with screw driver.
I would be grateful if you could more details of your gunwhale rollover solution
special fittings and extent of wooden support?
best wishes
