I have bow rails fitted to my warrior 165. the mrs wanted them, we use to enter the boat through the front hatch as it sits an a mooring so they were handy to hold on too. Other than this and i like the look of the boat with them they serve no other use.
I have a two battery set with one located a the rear and one in the steering console. Also located in the console is a VSR relay two isolator switches and a parallel switch cluster.
