Plywood floor in alweld boat

[jdm4x43732]

I have a 1648 Alweld boat I picked up to put my Go-Devil on to do a little duck hunting and maybe chase some reds. It has ribs 12" on center and if the kids come with me I don't want them to trip walking in the boat. Any of you have advice on what thickness plywood to use on the bottom, aluminum would be better but it isn't in the budget for now. Read a few places that treated lumber will eat up the aluminum. Anyone ever had bad luck with this? I'm gonna paint what ever I put down and waterseal it.
thanks guys.

No thinner than 3/8 inch. If you know any shrimpers, get some of that green net dip and paint it on. That stuff is non skid and last a long time.

i used 1" with ind/outd carpet treated worked awsome....made a template and had it fit super snug and never screwed it down..

1/2" AC fur is the most rot resistant wood you will beable to get...an coat it in Zintox treatment..slap you some paint on it, throw a little sand on the first coat then light coat over that. Go check out Dustin's surface drive boat. I have this in my 15' since '07 and not one bit of rot yet, light and holds weight real good.

1/2 in is perfect for that. I have it in my 15 ft boat, go with treated and then use stainless screws for sure. I used cardboard for a template and drilled small pilot holes through the ribs and screwed it down. Had the boat for 10 years and only replaced it once b/c I was cheap and went for the untreated wood the first time

I used 1/2"' AC then painted. Did not screw down works good.
