just brought a birchwood 25 executive, want to know if any one has done or has advice on making the roof detatchable and the windows hinge, the side glass is not split scren so was thinking about making them removable on wing nuts or similar, how heavy would the roof be, could two people move forward to roof of cabin

Looks pretty heavy to me...

Perhaps a soft-top conversion would be an option?

Otherwise, consider opening windows like old lucky lads have on theirs, or a large cockpit fan!

know i can do soft top but they look much better with hard top should have found a boat with smaller air draft, but really like these. il have a think.

Hi Ian
Can't offer any specific advice, but if I was to do something similiar, I'd explore the possibility of creasting a sissor type mechanism bolted either side that may allow the roof to be pushed forward, coming to rest above the cabin. You would of course need someone at the other end to cushion the 'drop'. I'm a mere (poverty stricken) 22 owner so I'm not sure if the 25 would give you this option. With enough money and DIY skills, I would have thought that new screen panels could be made up and hinged accordingly, using a piece of alluminuim between the screens to deflect the rain etc. I've had a hire craft in the past with this arrangement.
