Not marine grade but have you ever seen 13 ply – plywood? I’m using this to replace my dried up transom access panels.

I’ve seen cabinet plywood like that. What type and grade is your plywood?
October 19, 2015 at 7:03 am #1571749I have a whole bunch of that plywood in the shed. My bro-in-law gets it at work. Or there is a cabinet grade that we used to make drawer sides at the cabinet shop, it was called appleply. It was really made out of birch.
October 19, 2015 at 9:03 am #1571780Yeah, this is birch. I think it is called, “baltic”. I was told that it does have exterior glue. I’m planning on sealing it real well with a good sealer and then putting a couple of coats of colored bed liner on it.
October 19, 2015 at 12:11 pm #1571872Hmmmmm. That looks like MDF ply layers inside. If that is MDF this is bad news. The glue may be exterior, but the MDF will disintegrate if it gets wet.
You’d better figure out exactly what you have here before doing a lot of work that comes undone.

My intital reaction was baltic as well, but as Grouse points out it seems odd the mdf is on the outsides of the boards, typically you have a finished birch, oak, maple, etc on a “finish” side. Either way that fiber board will be destroyed instantly and forever if it ever gets in contact with water.
Stuff is tremendous for cabinet and other furniture making because of their resistance to expansion/contraction from HUMIDITY. Actual water is a completely different animal. Save it for a coffee table, not a boat IMO.

October 19, 2015 at 2:05 pm #1571911Baltic birch’s core is unlike traditional plywood you may be used to seeing: the layers of inner plies are 1.5 mm-thick solid birch veneer, cross-banded, and laminated with exterior grade adhesive. It’s a recipe that results in a void-free core with a number of advantages, which is why in the U.S. we’ve discovered that the material is fantastic for thousands of projects in woodworking.

October 19, 2015 at 9:23 pm #1572041Yes, Baltic birch, that is the sa.e as appleply. Back in 90-91 I worked at a trucking company that was developing a plywood product with a lumber company in Canada to be used as flatbed trailer flooring. It was called transdeck. It came in 1 1\8 to 1 5\16 thick 4X8 sheets. The company has since moved to Spooner Wisconsin. Argonne distributing was the name of the company. Google it and see if it is still available. The guys name is Steve, looks like he is still in business. He might be able to ship you a piece the size you need. This stuff is the real “serious plywood”

It’s called a leash.
