I just happen to have a photo...
Here is a cabin shot of the 2820 XL that
Boatron brought to the Annapolis
ClassicParker rendezvous.
Even this close, the new roof design is not readilly noticable, and it does provide two benefits...
1.) The first advantage is as a wire chase, as Dale mentioned. Radar, nav-lights, GPS, VHF antennas... Everything can be run inside for a clean install.
2.) The other thing that the 'bulge' does is to provide a means to channel rain or spray water off to the sides of the pilothouse, and away from the rear door.
I can't say that I like where the horns are mounted, but that is a personal thing. I'd end up stepping on them.
I don't have a detail photo, but inside the pilothouse... in the rear corners where the wiring would ordinarilly travel (vertically) down from the roof channels, are removable starboard panels. Those panels are about 4 to 5" wide, and allow access to run wiring down to the wire chase areas where all the present wiring goes forward or aft. A
much better solution than the small wiring tubes that I have in my 1996 model cabin.
It seems that the designers have realized the realities of todays electronics hungry boaters, and made accomodations for the cables we try to stuff into our cabins. :wink:
I like my flat roof... but this design does solve the a problem, and keeps the interior from looking like a wiring nightmare. :mrgreen:
