WOOD/EPOXY

Wood is relatively easy to cut and shape and almost everyone has some basic knowledge and experience of working with it. It is aesthetically satisfying to work with because of its inherent beauty. Its stiffness, light-weight, and resistance to fatigue give wood advantages over other materials for boatbuilding.
Besides its advantages, there are also some well-known disadvantages. Specifically, wood is subject to rot. It also shrinks and swells with moisture and temperature changes. And it looses some of its strength and stiffness after absorbing moisture. The root cause of these problems is the passage of moisture in and out of the wood cells.
To a very great extent, the use of wood/epoxy system overcomes the above problems. Boats built in this system have all of their joints bonded with, and all of their surfaces encapsulated in epoxy resin. Thus every piece of wood, both inside and the outside of the hull, is covered with a barrier coating of epoxy resin through which no significant amount of air or water can pass. The result is that the moisture content of the wood is stabilized. This stabilization in and of itself means that there will be little shrinking or swelling of the wood. The level at which the stabilization occurs, and at which it remains, ensures a continuation of design strength and stiffness. In addition, it prevents rot not only by stabilizing the moisture content, but also by restricting the oxygen supply to the wood surface.

Plywood: As already mentioned, wood is anisotropic; it has very little tensile strength across its grain. To overcome this shortcoming, and to increase its strength and stiffness in relation to its weight and volume, the practice of cutting wood into thin sheets and then bonding the sheets together with the grain going in perpendicular directions in alternating layers is used. The individual sheets, before they are bonded to each other in layers, are known as veneers. Veneers come in a variety of thicknesses, in a variety of quality grades and from many species of wood. A bonded lay-up of at least three plies of veneers is known as plywood.
Only marine grade plywood should be used for boatbuilding. (Conforming to BS1088 or BS6566). Exterior grade plywood uses the same glue as marine ones but in marine grade only a minimum of voids are allowed in the core and in general better quality veneers are used. In most cases, it has more plies for the same thickness that makes it stronger, but also more difficult to bend.
