Hi,
this spreadsheet has been around for a while, Roy (1770) and Brian (formerly 1773) have been working on it. While sail number 957 isn't on there you might recognise some of the boat owners names around that time and find the history that way.

If you can fill in any gaps in the spreadsheet PM me and and I will pass them on to Roy.

Alternative you could take a few pics of 957's hulls, internal too and we might be able to work out some info.

If anyone knows the Carter Hulls story it would make an interesting read. I've heard snippets of info, apparently he churned out Mosquitos by the dozen, did it in his spare time and was a wood working teacher, any more info out there?

I've owned two plywood Carter hulled Mosquitos and have been told my current boyer hulled boat (1704) is a copy of the Carter hull though it seems a bit more buoyant up front to me, rocker looks the same though.
