Cal 30 Port Lights

[Cal30]

Hi all
I have a Cal 30 built in 1966 that I plan to do some water sailing">blue water sailing in. I need to replace the plastic in the ports (windows). The frames are made of aluminum. So my Question is how strong are the frames? Has anyone had experience with this type of window frame failing.
Hopefully someone who has experience sailing cal's with these windows.
Thanks

If you sail to the tropics you'll want to have some opening ports and may want to fit ports into your current deadlight spaces.
kind regards,

Overhead hatches are the most efficient ventilation. Opening ports don't do all that much for a boat at anchor oriented into the wind.

The Cal ports are too big for sailing in a serious storm. You can easily handle that by making up shutters from plywood. Buy yourself a batter powered screw gun or drill and install with self tapping screws if the need should ever arise.
