Purchase marine plywood online from websites such as RestorePontoon.com, BoatBuilderCentral.com, EdenSaw.com, Marine-Plywood.us and CenturyPly.com. Common tree species used in the manufacture of marine plywood include merenti, okoume, Douglas fir, teak and holly. As of January 2016, these websites sell all these types.
Look for marine plywood boards that are pressure-treated for microbial decay-resistance, such as those offered by Century Ply. Marine plywood that meets British Standard 1088 specifications are made of untreated tropical veneers with high resistance to fungal attack. Other important considerations include weather boil proof glue and thick construction. Commercial brands of marine plywood include Hydrotek Marenti and Aquatek Keruing. These brands are available on EdenSaw.com and Marine-Plywood.us, as of 2016.
