Hello, builders!
I want to discuss the size of the portholes.
The size that is offered according to the drawings is very small, I think. Something about 65 mm. I'm talking about the inner diameter through which you can look and receive light.
Either in the manual or on the forum, I read that it is possible to increase the size of the portholes, but do not get too carried away with this, as it can weaken the sides.
Has anyone who has already built a boat enlarged the portholes? In what sizes?
I would like to make my portholes about 75-80 mm in diameter in the clear part. I think this will not reduce the strength of the sides. Besides, I want to make flanges inside and outside.
Or maybe the original size offers is quite convenient to use?
