What window caulk to use?

[SVLydia]

I am replacing the side windows in my Telstar 28 trimaran. Can anyone suggest a good caulk to use?

The current windows are caulked and then screwed into place. The windows are all flat.

I am not experienced at this type of project, so any advice is welcome!!

Thanks!

I use marine silicone to seal lexan windows held in place by a bolted through metal frame. This is the recommendation from Don Casey in , This Old Boat. I replaced all of the non-opening lenses in 2018 and everything is still water tight despite living in Mexico and French Polynesia for several years each.
