In a clockwise direction 480mm / 845mm / 415mm / 585mm
There is a rubber seal all the way around all sides of each window frame. The rubber runs down the middle between the 2 separate frames. Only problem with this is that I have not been able to identify the correct rubber to replace the original. I have re-used my original rubber but it dosent look as good as I would like...the search continues.
I made some templates today out of 18mm mdf using the measurements given. I cut the middles out to reduce weight and make it easier to move them around.
I must've got a couple of the angles wrong as when I placed them on the boat the top of the fronts touched but at the bottom there was a big gap. That lead me to think that the fronts were leaning too far back so the front angle of the side pieces must be wrong.
Only thing is, if I make that angle steeper it makes the 845 measurement longer
Maybe stating the obvious but if you can make your templates a good fit why not copy them in hardwood frames mortised and tenoned and rebated to take tempered glass. Looks like you have the gear and workshop to do it. Secured with screws and sikoflex should be strong enough to hold the canopy.
That's the plan now as a new aluminium frame with glass is gonna be silly money. The boat is stored 20 miles away from where I work in the workshop but I'm planning to try and scribe some templates to fit nicely then make some frames up. I don't want them to protrude past the lip at the side so I've only got about 16mm to play with which isn't much.
Just a trial run to check that everything fitted ok and I'm happy that it does. A small amount of planing to do to get the tops of the fronts at the same level as the sides but nearly there.
I've got the rubber for the windows and also the insert and a trim to go around the top and bottom to stop water ingress.
It will have 6mm perspex windows.
It's made from 9mm marine ply and it will be secured to the boat with screws and all joints will be stuck with Sikoflex ebt and the 3 angle brackets as seen in the picture. It will be sealed, primed, undercoated and glossed the same as the rest of the boat.
