I fished out of Fish and Ski fiberglass boats for about 10 years. When the second one was sold I vowed never to get a walk thru, or dual, windshield again.
Bought a Ranger last year. It is a dual console(it was hard to find alot of single console bassboats which tells you something right there)which I was very skeptical about because of the walk thru windshield experience. It is has been absolutely no problem having the extra console. In cool weather it is actually preferable. I have sat in a single console boat during a cool weather run down the river and it is no fun. The dual console definately helps your passenger stay warmer.
If the dual console has glove compartment storage that is a plus, especially for little things like extra spool of line, scale, and a whole bunch of stuff.
On deck rod storage is no problem, even with 7 ft rods or an 8.5 ft fly rod stapped down (19 ft Ranger).
Would definately recommend dual console. Some boats come with removable consoles that can be taken out during the warm weather months then reinstalled later. Just a few screws. Ask your dealer if that option exists.
