I know a guide who had something similar made for his Parker. He has a Bimini top that has front, rear, and side curtains. In cold weather he puts the pieces up and runs a small Coleman propane heater that sits on the console. Takes the edge off the cold and there is tons of room to move around inside the enclosure since it is the full width of the boat. As the weather warms he pulls down the curtains--makes for a great 4-season boat.

I've always thought this is the way I would go if I was fishing 365 days a year in an area that had blistering summers and chilly winters like the northeast.
