Gaboon Marine Plywood is the slightly less flashy alternative to Hoop Pine. It has an A-Grade front face but uses a B-Grade for the back, making it a cheaper option. It’s available in a 2440 x 1220mm sheet size and six thicknesses (3mm, 6mm, 9mm, 15mm, and 18mm).

Next up is the step below Hoop Pine and Gaboon; Pacific Maple Marine Plywood. These boards are manufactured to British Standard and feature a B-Grade front and C-Grade back, allowing them to be cheaper than Hoop Pine, with the caveat of not looking as fancy or being as good an option for something as intense as boat building. Much like the Hoop Pine AA Marine, Pacific Maple is available in seven different thickness (3.6mm, 6mm, 9mm, 12mm, 15mm, 18mm, and 25mm) with a single 2440 x 1220mm sheet size available.

Furniture Making

What is the thickness of marine ply?

If it’s furniture you’re after then there’s a number of different thicknesses perfect for specific needs. If you’re building something along the lines of a table, you’ll be looking for something in the 18 to 24mm ballpark. Meanwhile, drawer sets typically involve a combination of 16m and 12mm ply. Other pieces of furniture tend to vary on a case-by-case basis, and if you’re looking to build something not mentioned here and are unsure what to use, get in touch with us and we can help you out.


Some people also like to use Marine Plywood decking or flooring as an option in outside areas, a natural choice due to its built-in properties (see this blog post to learn about Marine Plywood properties). For flooring, we suggest anything within a range of 15 to 25mm.
