Porthole and hatch sizes on Lagoon 560

[Amara]

Hi All-
I was wondering if anyone might be able to help me. I am currently trying to order a new port hole that is located in the owner's cabin. However, I don't know the dimensions and I am in the US and our boat (and spec catalog) is in Australia. I'd like to order one along with a screen and bring them over when we return to our boat in March as we are heading to Indonesia. Anyone know the standard size? They are Lewmars. Also, while I am asking, do you know the size of the standard hatches? They are the flush Lewmars as well. I am trying to order mosquito netting hatch screens for those hatches and want to make sure I get the right size.
I can get someone out to our boat to measure them, but I thought I would try Cruiser's Forum first!
Anyone that can help, thank you in advance.
