Ed,
I have used a fiberglass, 14 foot, double end, decked, Appleton marsh boat since 1985, and found it to be a very good duck hunting machine.
Do to a back injury, it has not been in the water for a few years. I cannot wait to use it again. In a few months God Willing I'll be 70.
Peaceful and stealthful it is.
This is what I have learned early on, concerning it's proper use.
1) Everything in the vessel must be kept at a low center of gravity. This includes YOU.
2) A boat with stake holes, fore and aft is the only way to go.
3) Always carry 2 paddles, and have at least one secured with a line and snap swivel.
4) Make a gunning box (instead of a blind bag) to carry what you need out of the wet, and to cradle the shotgun in a safe position.
5) Wood and cork decoys make very good ballast. 2 giant Canada geese, and eleven duck, and coot decoys are all that is needed.
6) A wooden backboard, and a float cushion for yer butt, keep you out of the wet, and are better than a seat. Plus you will need the cushion for your knees when you paddle.
7) Lightweight camo netting, over the cockpit and you is all that is needed for very good concealment.
8) Everything in the vessel has it's proper place, before and after setting up.
9) Always carry s large sponge, and plastic scoop bailer.
10) In cold weather nothing beats 5mm neoprene waders, Hot Hands Body and Hand Warmers, in all the right places.
11) Wet heavy snow is to be taken very seriously, if you value freeboard, and your safety.
12) A good thermos with a piping hot beverage, soup, or chowder, and a container of water, cuz you will get a good work out.
You will have fun, and some of the most enjoyable, and quiet (except for your shooting) waterfowl hunts of your life.
Best regards
Vince
