Marine plywood such as Hydrotek, produced to European standards, offer more ply’s, and are uniform in specie throughout the panel (Red Meranti). These panels are less expensive than the European Okoume marine plywood, and they offer a greater durability and hardness than Okoume panels, however they are always heavier then Okoume panels, and typically not produced to the same quality standards. All of these panels we are discussing are produced with a Phenolic glue line, which is a waterproof glue.
