Re: carpet
my issue is with the noise. Alum. boats are noise producers and aluminum decks are the worst. Easy to clean yes, but the noise is irritating.
But I'm not convinced yet... so let me hear some other suggestions on how to make the boat more quiet.
I have a 1436 Tracker Jon and didn't want it sounding "tinny" either as I'm after big spooky fish. This is against what most would do to their boat, but here's what I did.
#1, lay rubberized roofing membrane on the deck/hull, it's a 12" wide roll of self stick asphalt based material.
#2 low decked the boat with 3/8" plywood and added foam between the decks and hull, the foam touches the hull and dampens the noise. (touches,,, is not adhered to the hull)
#3 carpeted the decks and hull sides.
The boat is one heck of a lot quieter than it used to be,,, but is kind of a PITA to keep clean. Vacuuming carpet, removing decks to clean underneath...
If you have non-removable aluminum decks above the hull, you won't be able to do what I did to quiet the boat. Or I should say,,, I wouldn't foam under the decks as it could turn into a big spounge and soak up water, a lot of extra weight. The roofing membrane wouldn't be a good idea either if it's exposed as it can leave marks, think asphalt.
You could add snap-in carpet sections though, like they have on a lot of new boats. Carpet snaps onto the deck and can be easily removed for cleaning.
