Marine plywood, in layman language, is generally BWP or boiling waterproof plywood. The name of these plywood suggests that these are used for the boat construction industry because they are highly resistant to water. Boats require a tremendous resistance to water.
It is the strongest and toughest of all plywood on the market. High-quality glues hold the plies in marine plywood together. That makes them structurally sound and resistant to moisture.
Marine plywood is ideal to form simple boat structures, and as long as it is properly sealed inside and outside, it will be waterproof
