    Default Subfloor weight question

    So if I was to take the subfloor out of my 19' CP about how much weight would that take out of the boat? Its 4" tall and carpeted and I don't believe any water stuck in it because it looks glassed in pretty well.
    I remeber a while back Slow Burn took his subfloor out and said it weighed over 100lbs but I could be mistaking.
    How hard is it to take out and what's the purpose of the subfloor anyways?
    Thanks.
    Trevor.

    Often times we remove these from full stringer boats, for example beneath the sub in my Bahner we found wet foam a saturated center rib and nasty mold crud, although the floor may lend a modicum of structure many boats were built without it altogether, figured we saved or eliminated around 50 to 75 lbs

    thanks, how much time did that take, does taking the subfloor out take any strength out of the boat?

    Default subfloor

    I removed the 3/4" waterlogged subfloor from my Rogers a few years ago and it weighed almost 100lbs. I had no issues after removing the floor but the boat was a 720lb layup.

    Thanks for replys guys
    my carpet is pretty hammered, my goal is to take the subfloor and all of the carpet ou then have the floor and stringers glassed over for a clean golssy look, I know where I previously removed the carpet by the tanks the floor was really good looking.

    Real quick just some "brute force and ignorance"
    ... Found the perfect tool its a small handheld electric device with an oscillating blade , doesn't generate much dust and is very precise cant remember what the are called but just about everyone sells them as far as strength I think any structure loss was was negligible similar Eliminators to my boat had no false floor might want to ad a small bulkhead in frt of the engine or bilge water blows forward on decel

    I pulled out the subfloor on my old condor gwing and it weighed 103 worth of saturated shitttt i put in a small subfloor between frt seats jus for nos bottle n divertor left the rest of floor open, carpeted it.honestly felt alot roomier inside and losing 80lbs forward of cg helped alot.. i never missed the floor after goin without it.

    Dare to be different, if it turns out great you can claim you planned it that way.

    Scotty made the sub floor removable from mailman s boat. Made it outta balsa, looks good, it's removable when you want it out, and looks badass without carpet on it. Can't remember what it weighed, I wanna say around 70lbs

    Cutoff airtool,grinder and facemask but the tool tom posted wld make doin it gravy! My gwing had the floor glassed to the inside of stringers so i jus got in the side corners and cut it lose from stringers, dug out all the smelly shit and let it dry a day or two.went back and did what i cld to smooth stringers, then carwashed it all out and let it dry a wk inside my shop.carpet went in..im kinda a carpet junkie, i dont like bare floors. looks nice but ill take carpet weight for the comfort on my lil piggies lmao

    3/4" plywood weighs about 2.25 pounds per square foot. Soaked with water I am sure it will be even heavier........Skip
