Due to cost, I'm looking at putting a plywood floor instead of aluminum in a small flat bottom.

Update:

Baws, got floor cut, went with 1/2" marine plywood. Question: it's a flat bottom boat with a gradual rise at the front. Any tips on how to bend the floor to where I can screw it down on all the ribs? Currently it's not touching a couple in the front.

tinboats.net is a great resource for this, several different products out there, some more expensive than others.

Marine grade plywood probably wouldn't warp much fwiw, just depends on how much effort you want to put into it.

One big thing I can tell you is weight is key. I have a 40 hp on a 14x48 and it rolls good. I previously had a 15 on it before i built the decks or anything. I knew it wouldnt be enough. What size motor do you have?

I have an estimate from a welder to install a 1/8 aluminum floor for $700...that seems high but I really have no idea on what the cost of aluminum is.

That would include welding it flush around the ribs.

I had compared the price to do all of mine in aluminum including the framing and it was around $1500. With plywood and 2x2 framing, i only spent about $300. Plywood isn't that much heavier than 1/8" aluminum if i remember right.

I'm working on the pictures now.

My dad and I built plywood inserts and sealed them with some kind of polyurethane for mine when I was a kid. Took em in and out as needed and they stayed put while running and trailering.

This is what i was running before. It had a floor in it that the carpet was all torn. Ive had this boat since I was 16. Yes my neighbor used to have a pony.



Put a lift plate to make the 20" motor work.



I had to trim down the old wide console to what I needed. I made a cap plate from aluminum to cover the opening and mount the controls to.



Here is the front deck in progress. I have some inside built pictures at home. Its basic 2x2 framing with a full width hinged door. The deck and door are 2 pieces of 1/2' osb screwed down. I forgot the exact material I made the floor out of. It is stuffed with EPS foam all underneath and compressed down when i screwed the floor down. it doesnt flex at all with all the foam underneath. I then spray foamed the edges becuase sides werent in my original plan.


Finished front deck


Floor carpet cut to fit.


Got floor glued and stapled down. Used a floor roller i borrowed from a buddy. Really works out the waves.


This is where I'm at now. Plan on doing the side piece by the console this weekend. and finishing the trim.

Ive done alot of reading and learning as I go. If you wrap the carpet before putting the floor down in the boat, its a whole lot easier. But i did it arse backwards. Ive trimmed it out part of the ways. I didnt wont anything to break the bank or fancy. I dont mind throwing mud or blood all over it.

I work for a hardwood lumber importer in Mobile. One of the many things we import is Burmese Teak and Okoume Lloyds of London Certified 1088 marine grade plywood. I sell this lumber and plywood to high end yacht builders primarily on the East Coast and lots of repair shops on the Gulf Coast. I would use that Okoume marine grade plywood we import. It's durable as hell and it's lightweight. That's the way to go if you want something durable yet lightweight. If you need 1/2" you will need 12mm.

Thanks. Would you recommend treating it in anyway? Is there a retailer you know offhand?

Where do you live? I'm no finishing expert but that's the best plywood for marine applications. Most of that other marine grade plywood is very heavy and for exterior use but not all that great to stick on a boat.
