I personally do not ahve a duck bill, but my buddy has a 1548wareagle with one and i hate it. Its hard to get it on and off the trailer. puts the trolling motor on there funny,a nd the lights are not real bright. I do like it for dragging the boats,a nd its nice to step on, it doesnt get icy so you wont bust your butt!
Personally I would have someone build you one. Back when I had my War Eagle I tried for a whole summer to get one put on and after 3 months of trying a old man at war eagle told me to sell my boat and buy one with one on it. I gave up after that
I run my boat turkey hunting, fishing, frogging (catching off of the front deck), deer hunting, squirrel hunting and duck hunting and I can't think of a single thing that wouldn't get in the way of. I've been running a boat in timber for about 25 years and never had a need for a brace I want my spot light to shine wherever I want it to and at the exact second that I want it to. I'm honestly surprised you guys find those things useful. Are you guys that are using these just running your boats for duck hunting?
