Overview
Choose the marine construction for your boat component
Marine plywood is specified by its veneer construction and marine grade, alongside the bond. Choose Okoume-faced, all-Okoume or Sapele-faced panels to suit the visible surface, component weight and boat drawing.
For joinery, compare the face and finished detail. For hull or load-bearing work, follow the designer’s required grade, thickness and structural data. Our 18 mm, 11-ply SGS report provides the published bonding and panel measurements.
Okoume-faced, all-Okoume or Sapele-faced
Scroll horizontally to compare all columns.
| Construction | What to specify | Sample request |
|---|---|---|
| Okoume-faced | Okoume outer veneers with the inner species, marine grade and bond specified for your component. | Okoume-faced sample |
| All-Okoume | Okoume throughout the veneer layers. Add your sheet-weight target, thickness and required marine grade. | All-Okoume sample |
| Sapele-faced | Sapele decorative veneer over the specified marine construction. Include matching, reverse face and coating for visible fit-outs. | Sapele-faced sample |
Face, inner veneers and back: read the construction
For a lightweight component, compare Okoume-faced and all-Okoume constructions at the same thickness, then include fittings and coatings in the finished weight.
For outdoor joinery, see exterior-grade plywood. For concrete formwork, see film-faced plywood; for freight-container floors, see container flooring plywood. These pages help match the panel to its intended use.
Read the marine versus exterior comparison, bonding guide or finished-part cost guide for your purchase.

Configuration
Marine grade, bond class and finished protection
These three choices answer different questions: the marine grade describes the panel requirements, the bond class describes glue-line performance, and the coating system protects the finished component.
- Marine product grade
- Use the standard and edition named on the boat drawing. Veneer species, construction and panel quality belong in the specification alongside the adhesive bond.
- Bonding requirement
- The published SGS panel records Class 3 bonding quality. A bond result alone does not establish every property required for a hull, deck or structural component.
- Component protection
- Include faces, cut edges, joints and drilled openings in the coating plan. Follow the coating and hardware manufacturers’ preparation and installation instructions.
Compare marine and exterior plywood or review WBP and bond classes before choosing an alternative.
Inch drawings and metric sheet sizes
Our regular sheet formats are 1220 × 2440, 1250 × 2500 and 1525 × 3050 mm. Request 1220 × 3050, 1250 × 3660 mm or a cut-part format for your layout. A 4 × 8 ft drawing equals 1219.2 × 2438.4 mm; state whether the drawing requires that exact dimension or accepts the offered metric sheet and trimming allowance.
Scroll horizontally to compare all columns.
| Drawing reference | Exact conversion | Take into the inquiry |
|---|---|---|
| 1/4 inch | 6.35 mm | Required finished thickness and tolerance, joint/groove fit and the proposed metric construction. |
| 1/2 inch | 12.7 mm | Part duty, facing/core and bond designation alongside the measured thickness and hardware detail. |
| 3/4 inch | 19.05 mm | 19.05 mm on the drawing and the supplier's stated nominal/finished dimensions; compare tolerance and fit when considering an 18 mm offer. |
These conversions describe the drawing requirement. The quotation identifies the thickness available for the selected marine model, its finished tolerance and any accepted dimensional alternative.
Locker-panel example: hinge holes, cut edges and coating
For a coated locker panel, select the face and core against the drawing, machine the hinge recess and fixing holes, then coat the faces, edges and openings. Compare hinge fit, edge condition and the finished appearance as one assembly.
For the quotation, attach the panel dimensions, selected construction, cutting list and quantities. Use the coating and penetration brief for workshop details.

FAQ
Common buying questions
Can CUZI supply 18 mm marine plywood?
Yes. The SGS report covers 1220 × 2440 × 18 mm, 11-ply marine plywood. Send your required face/core construction, marine grade and quantity for a quotation, or request an 18 mm sample.
Which thicknesses and sheet sizes can I request?
Regular plywood formats are 1220 × 2440, 1250 × 2500 and 1525 × 3050 mm. Other formats and cut sizes are available on request. For 4, 12, 15, 25 mm or another thickness, send the marine construction and grade you need; availability is confirmed in the quotation. The published SGS results cover the 18 mm tested panel.
How do I choose lightweight marine plywood?
Start with your maximum sheet or finished-component weight and required marine grade. Compare all-Okoume and Okoume-faced constructions at the same thickness and size. Request measured panel weight, then include hardware and coatings in the completed part.
Is marine plywood waterproof?
Marine plywood has a water-resistant bond, but the wood still absorbs moisture. Faces, cut edges, joints and openings need the protection specified for the boat. The SGS panel records Class 3 bonding quality; use the coating and penetration guide for the finished detail.
What should I request for BS 1088, E0 or another specification?
Specify the marine standard and edition, and name the emission test method if E0 is required. The published SGS report lists tests against BS 1088-1:2003. BSI’s current edition is BS 1088:2018. Use documents that match the selected construction and the edition required by your project; emission testing is a separate requirement.
Can I order decorative faces or cut-to-size panels?
Yes. Decorative faces and cut-to-size processing can be specified for the selected marine construction. Send the facing, reverse, finished thickness and cutting list. Include grain direction, holes or profiles and quantities by part. We will quote the requested work and sample for your selected marine construction.
Is 3/4-inch marine plywood the same as 18 mm?
No. Exactly 3/4 inch is 19.05 mm, which is 1.05 mm thicker than 18 mm. Specify the required finished thickness and tolerance for the drawing and joint. Our sheet size and thickness guide compares inch and metric dimensions.
What determines the marine plywood price?
Thickness, veneer construction, grade, required documents, processing and order quantity affect the quotation. Send these with your FOB shipment port or CIF destination port. If you have a drawing or an existing specification, you can start with that.
What are the minimum order, samples and lead time?
Orders start at one container, with mixed loads available. Samples are free; buyer-paid sample freight is credited in full against a formal order. Regular production takes 7–15 days, plus shipping. We accept T/T and L/C; your quotation confirms the order schedule and payment terms.
Is WBP plywood the same as marine plywood?
No. WBP describes a water-resistant bond in trade usage; it does not define the veneer construction or complete marine grade. Buy to the named marine standard and edition, with the required core quality and product data. See WBP plywood for the bonding terminology.
Is all Okoume plywood marine plywood?
No. Okoume identifies a wood species. Marine plywood also needs the specified panel construction, marine product grade and bond. Choose Okoume on the faces or throughout the layers, then match that construction to the boat drawing and its required documents.
