Hi

I have recently bought a Colvic Springtide and the previous owner gave me two of the original drawings showing Rig and inside layout. i could take some hi res photos and send them to you if you want. Just send me an email to send to and ill do it as soon as possible.
it also gives all the corect lengths for the sails and rigging.

i live in southampton if you wanted to scan the 2 Drawings.

good luck
Dylan
