New Boat Floor

17 posts in this topic

I was just wondering how thick of plywood would be best for a new floor in my 16' crestliner. Also if I use regular plywood and treat with a fiberglass resin will the marine carpet glue still stick to it. Thanks in advance for any help.

Measure the thickness of the plywood that's in it now. 90% of the time, it's half inch. We haven't had any adhesion problems in the last 20 years, glueing carpet onto the resin. If you have any doubts, run a grinder or sander lightely over the resin to give it "tooth" for the glue to hold onto.

Steve, I've read any number of times, where both you and Valv have recommended using resin to preserve your plywood boat floors.Exactly what kind of resin is it? When I go into the paint store, just exactly what do I ask for? Do you need to do any special preparation on the plywood before applying the resin? I have a half inch floor in my boat. When it's time to replace it, I was thinking of using 5/8". Do you think that would work OK? Thanks in advance for your help. smile.gif 1DIRTBALL wink.gif

You don't have to go to paint store, the resin it's just plain fiberglass resin. Go to a Walmart, K-Mart, etc. they have it in the automotive section, very cheap to purchase.

So would marine plywood already have this resin?

I replaced my floor last year and put 2 coats of Spar varnish on instead of resin. Did I make a mistake doing that?

We used 5/8" plywood on our floor on the areas that had to span more than a foot or two (casting decks). In the floor, we just ran supports underneath and put 1" pink foam underneath to provide a good tight fit with 1/2" plywood.

We did the same thing with our boat floor 3 years ago, and I think, esp. with the spar varnish, that the carpet will wear out long before the plywood does.

I keep the boat covered during the summer and in storage during the winter, so I hope that there are some things that I am doing to help myself and the boat out. I really try to keep it dry when not in the water.

No, marine plywood doesn't have any resin, it's a rare product with no voids (air gaps) petween sheets and woods.

There is not need to get it, you can use plain 'ole plywood if you are going to cover it with resin.

DON'T use treated lumber, or it will have a chemical reaction with aluminum.

5/8" would be just fine as long as it fits. Some boats run the floor up to the lockers and casting decks, and some run the wood under. If your's goes under, then thicker wood will make everything sit cock-eyed. You'll need to either go with the stock thickness or stop the wood at the edge.

What will it do to the aluminum, I was looking at putting in a front deck over my bench seats in my 14' boat. It would only have contact with the aluminum on the edges (if that, because it will be covered with carpet). I thought maybe treated would hold up better in this case.

ACQ treated lumber eats aluminum. The only metals that can come in direct contact with it are double dipped hot galvanized steel, stainless steel or deck screws treated with approved chemicals.

Because it will often be wet inside your boat the chemicals are more apt to leach out and react with the aluminum.

Since they changed from cca to acq treatment 4 years ago treated lumber shouldn't be used anywhere in an aluminum boat. Your lumber yard should have warning lables near its treated lumber that it should not be used near aluminum siding and only attached with approved hardware. We have'em, but no one reads them.

Your local building inspector probably has a sample of aluminum siding that came in contact with acq. Within 6 months all of the aluminum within 1/2" of the acq will be gone!

Two years ago I saw the aluminum bed of a truck that had only made one 350 mile delivery with a load of acq, there were divots as deep as the thickness of a dime that had been eaten into the bed where the stckers sat. New treated lumber is wet and there would be alot of heat and friction from going down the road so it would be a worst case senerio.

Do a search for Universal Forest Products. They have alot of info on their web site about how corrosive acq is. All of the info will be about aluminum siding or fasteners, but aluminum is aluminum.

Was your boat Aluminum?....what did you use for supports and how did you attach them?

I would like to raise my floor up so it goes all the way to wall instaed of having a gap along the edge.....I have Aluminum stringers...... confused.gif

Thanks Pier....

Sorry for the late response.

Yes, the boat was aluminum......for supports, we kind of flew by the seat of our pants. Basically took longer 2X4's adn 4X4's (only where needed) and used skill saw and sawzall to shape them to the contour of the bottom of the boat. We ran them the length of the boat, maybe 6 of them?

It wasn't perfect, and there was some "rocking" so we pushed the 1" foam on top of the supports, between them and the plywood. This steadied it up and makes for a great floor.

Hope this helps,

Joel

      7/20 day 6 Today was was the feast day. Spending most of the day hanging on shore visiting and eating the weeks catch of fish for lunch and burgers and salads for supper.  Some water time for the kids and the wife.  Avas' parents also drive up to spend the evening around the fire.  It was quite the family affair.   Fishing today was targeted towards finding the big panfish for my folks to catch.  This plan was an utter failure.  Both boats out this evening and no one could find the panfish!  Frustrating to say the least. I decided late in the evening to go back after walleyes to try and put the folks on some fish.  I ended up boating only 1 northern 20", Dad landed a 18", 17", and 14" walleye, while mom boated a 14" walleye, and 2, 8" bluegills.  Not bad for a fall back plan the last hour and a half.   7/21 day 7   Today was a day to say goodby to My folks and the borther and sister inlaw.  As well as to start to sad action of packing up and being ready for our trip back home early the next morning. Our late afternoon was interupted by a nice strong thunderstorm that would rattle cabins, dump a ton rain, and light a couple of trees on fire around the lake from lightning strikes!  Also leaving us without power for 7 hrs.  It was a good storm. With the kids off to a movie, and the in laws on shore with boat.  It was just me off to lake for one last fishing outing after the storm.  With only a little over an hour fish i hit our standard walleye spot.  With old faithful providing me with two small walleyes 12" and 14".  The darkness came and fishing for the week was over.

      I was to Graceton a couple of times and saw the boats but never saw the fish. I really like that are but missed it this year. Bouncers in reeftops is hot as heck right now. Lemms was loaded with big biters yesterday. Good plan. I have been jigging out in the mud, more and more fish out deep every day. Good luck
    • srj
      Hey Curt, not me. But I might get over that way tomorrow as I'm coming up this afternoon. Depending on the wind, I hope to go reef hopping pulling bouncers rather than trolling. I'm curious if the big school is still sitting over east of LP, more or less in front of the Graceton cut. It was a big bunch of fish. A week or so of stable weather would sure be nice. The only  time the wind seems to blow from the same direction for more than a day is if it is somewhere out of the north.
    • curt quesnell
      Nice fish and plenty of them is what has been happening this week. Almost as many slots as keepers.  We have been jigging but pulling spinners or cranks works great too. One of the attached pics is what is showing up in the deep mud, mostly Saugers now but more Walleyes and tons more fish piling in the next few weeks. Joe Paradis from Plummer Mn out with me this morning behind the fish board and, from Thursday fishing buddy Mike Lindholm with the biggest, fattest, best looking 25 incher I have seen in a while. Having plenty of fun fishing in the wind

      Thanks for the reports. Steve, were you at Long Point today? I saw a Stratos

      Bugs have been brutal all summer up their.   Glad you had fun!!!
    • JBMasterAngler
      Well, we went back up there to make up for last month. There was no making up anything! Bugs were horrendous, and the fishing was slow to nonexistent. The biggest point of going back up was to fish West Bearskin and Two Island lakes, and we didn't make it to either this time around either.    We still had lots of fun. Did a lot of hiking and sightseeing, particularly on the way up and he way home. Seen a lot of things I've never seen before. Was nice to sit out by the harbor and eat Sven & Ole's. Definitely a lot more people up there in July, as opposed to June. Well, we'll be back in October.

      Yeah I like decoys this thread used have some on here. I will try to hit a show Thank you
    • delcecchi
      BTW the "no fish on my spots" was just a riff on Tom''s "no fish under my dock".  Sorry for any confusion.  I'm not much of a musky fisherman, so wouldn't know if there are or not, really.
