Can't make up my mind on what roof window to fit to my SWB high top . Looked at plastic opening vents like the Seitz or (fan powered) Fantastic but they seem insubstantial and I keep coming back to the idea of fitting an alloy framed marine hatch.
I can get a flanged size 50 Bainbridge storm hatch for about £190 but it is 7kg - would this be too heavy? It would seem to fit neatly between the roof rafters ( 50cm) which look pretty strong. The Vetus 40 is only 4kg but doesnt seem as good. Any observations/advice ?
