Okoume is a relatively softer tropical hardwood tree from Central Africa - often Gabon.
Low in density, Okoume marine plywood is lightest in weight and most flexible among all the marine plywood products we offer.
It is approximately 10% to 20% lighter than the Aquatek and Hydrotek meranti plywoods, but is not as stiff.

Okoume marine plywood is ideal where light weight and consistent construction is important.
It is used for kayak hull and deck components, structural bulkheads and hatches.
Almost always used in in combination with epoxy and fiberglass overlays, on large vessels Okoume plywood yields structures that can be very strong while light in weight.

• Easy to work with for tooling, but high silica content can dull cutting tools
• Fine textured grain
• Color varies from pale pink to light brown; resembles mahogany
• Easy to finish, has a golden, honey-colored hue when epoxied or varnished
• Relatively low resistance to rot, generally sealed with an epoxy coating when used in marine applications
• Manufactured in Europe and certified by Lloyds to meet stringent BS1088 standard for marine plywood - notably, a relatively thick 1.3 mm (1/20") outer ply, no open surface imperfections, and few/very small interior voids.

Heavy on the technical side...

What makes a plywood "marine" is the waterproof glue used in its construction - WBP (weather and boil proof phenolic resin glue), and plys with no open surface imperfections, as well as no, or very small, interior voids.
Perhaps surprisingly, "marine plywood" has no designation for the type of wood used, or its resistance to rot.
Marine plywoods are not required to be built of species that are naturally durable.
It is recommended that the standard trade practice of applying epoxy sealers, paint or preservative compounds to both face surfaces and edges in order to prevent moisture ingress is addressed during construction.
Okoume Marine Plywood that is manufactured in Europe and certified by Lloyds of London to meet the British Standard 1088 for Marine Plywood is the best in the world, with the most consistent quality veneers, both in the core and the faces.
The European mills hire Lloyd's of London to monitor and test their quality and certify their products to be on specification. Some Asian mills claim their products are built to the 1088 specification, however none are Lloyd's Certified and few, if any, attain the quality of the better European plants.
If your project requires the best marine plywood money can buy, Edensaw's BS-1088 Euro Okoume is the way to go. It is the standard that specifies the quality of the best marine plywood in the world. Reading the entire BS1088 spec. is a long and tedious process. So we have condensed our list to the main headings. a) Balanced construction to avoid distortion in service. (4.2.3) b) Minimum face veneer thickness on all panels and no less than 1mm after sanding on panels thicker than 3.8mm ( c) Durability of species and glue type within standard or lightweight designations. (4.3+5.5) d) Dimensional tolerances (5.1) f) Moisture content (5.2) g) Allowable defects (5.4+4.1) h) Glue Bond Quality (5.6) i) Marking and Documentation (6.1+6.2) The above specifications are abbreviated and listed for convenience only and are not to be construed as the grade in its entirety. If you must have a thorough understanding of the British Standard 1088 please purchase a copy of the actual standard and study it. It can be purchased online at http://shop.bsigroup.com/
