Fiberglas Thickness - 1987 - Hull and Deck Repair

Hi all. Does anyone know what the thickness of the FG is on the deck? I'm about to do some deck/core replacement in the spring and want to be prepared with the right tools for the job. It's a pain to get equipment to the boat and I have a very small window of time to fix it in. Has anyone done this lately?

Just checking this forum, somehow I wasn't "watching" it. As far as contacting Tartan for that info I am afraid you won't get a good answer unless you get lucky with whom you speak to; it seems records were lost, as seems so often to be the case with yacht builders. I think you are going to have to just dig into it.

I'm curious as to your progress.

How did this project turn out? I am closing in on deck repairs on my sort-of-good old C27 and would benefit from your experience.
