What is marine plywood called?
Marine-grade plywood, often simply called marine plywood, is not what it’s often claimed to be. That is, it’s not waterproof. It is a good-quality, hardwood plywood made with waterproof glue, but since it’s not treated with chemicals, it is not rot-resistant.
What type of glue is used in marine plywood?

Can you glue marine plywood?

What is stitch and glue construction?
Stitch and glue is a simple boat building method which uses plywood panels temporarily stitched together, typically with wire or zip-ties, and glued together permanently with epoxy resin. This type of construction can eliminate much of the need for frames or ribs.

Do you have to fiberglass a plywood boat?
Although it’s a fibreglass boat, it will still require a plywood floor that will need to be reinforced with fibreglass matting. This is to protect it against the elements and to also form a waterproof structural bond to the hull of the boat.

How do boats not tip over?
A large cruise ship usually has several ballast tanks. So the combined effect of a ship’s buoyancy, low center of gravity, and ballast keep the ship from tipping over.
