Hi Kate,
I’m currently renovating W545 Lantana. This involves stripping down, redecking, repainting and a new setup, but not a great deal of structural work. I’m planning to keep the wooden mast too.
I do have the original measurement certificate, but intend to get her remeasured when complete to maintain her Wayfarer status (rather than for racing needs).
One thing I’m finding is that the quality of the 1960s plywood is outstanding. Planning to change as little of it as possible.
Email me at the address below if you’d like to chat over the experience as you go.
