Hi
I am very sorry but just seen your post message, i wrote The History of the Colvic Watson Motor Sailor and can send a copy if you are still interested.

That hull number identifies that the hull mould (not necessarily the launch date) and was made around 1980, I would be interested to know what size and type of Colvic Watson your boat is and when she was launched

Hi. I was wondering if you could tell me where I can get a copy of the 'history of the colvic Watson' document. Also do you know how I can tell how old a colvic watson is? I have the sail number from the hull which is 6593 and she is a 23'6 watson. Any help greatly appreciated. Thanks
