I'm revisiting my CAD models of the 77 footers- I've learned a lot about CAD since I did my first versions, and want to redraw the models from scratch using the best info available. Which isn't all that good.

Starting with the hull: I have lines drawings, and can get *pretty* close with those. But the gold standard for this work is the Table of Offsets- the lines described in hard dimensions. Having those values does away with all the errors that come from working with distorted paper drawings.

But the only TOO I've seen for the 77 is the one from the scanned microfilm roll. And as with many of the 77's microfilms, it's just about useless.

Has anyone discovered a clean and legible version of this?

Oh, and the same thing for the early and late cabins, some pretty dismal drawings out there.

I've posted them on Frank's MOSQUITO FLEET and my SMALL NAVAL COMBATANTS Facebook groups.

Well darn it all Al, I should be careful what I ask for!
Those are excellent, so now I have to go back and fix my sort-of-close drawing developed from measurements off paper.

Thanks, I'll post updates as I go.
