The type of wood used depends alot on the application. Teak is well known for its rot resistance and is used extensively for trim on the exterior and interior of boats. Mahogany isn t as rot resistant but is beautiful and can be used in many of these same applications. Many antique boats made by ChrisCraft and other builders used mahogany for planking, trim work and even structural parts. It is a very versatile wood.
White oak is strong and is found as structural members of many boats.
It is also used sometimes as trim inside and outside of boats or as structural members. Cypress is used in various structural applications. It is not as rot resistant as many people think, so constant contact with moisture isn t advisable. White and Western Red Cedar are often used for boat hulls. They are light weight and work very well with strip plank construction and cold molding with epoxy such as West System.
