Marine-grade plywood, often simply called marine plywood, is not what it's often claimed to be. That is, it's not waterproof. Since it's not treated with chemicals it is not rot resistant. However, it is a good-quality, hardwood plywood made with waterproof glue. Better grades also tend to be lightweight, strong, and virtually free of defects.
Tropical plywood is superior to softwood plywood due to its density, strength, evenness of layers, and high quality.
