Thank you. I think we’re going to take one of the windows out again and measure just to make sure.I think that @Firefly625 has a Mitchell 31 - he might be able to help with the info you require?
Indeed I do have a Mitchell, but I would not really like to guess the thickness of the gel coat. I have never measured it. Also as such bespoke boats many being built by different yards I’m not sure many two would be identical. There was a chap called Roy asking similar on the Mitchell Facebook group, if this was you then my recommendation still stands... drill a hole and have a look. Good luckThank you.

We went down to the boat today and took one of the windows out. Measured 4mm. Ours is a Mark 1 version but as you say all builders will be different.Indeed I do have a Mitchell, but I would not really like to guess the thickness of the gel coat. I have never measured it.
