This lumber is intended for use as solid straight or curved members in small boats, patrol craft, mine sweepers, and other wooden boats or ships where high-strength, bendability, and good decay resistance, either natural or acquired by preservative treatment, are required. Type I (white oak) material has good decay resistance throughout the piece except for untreated sapwood, which is strictly limited. It may be resawn or bored without effect. Type II (red oak) material, depending on the character of the individual piece, may have lesser decay resistance due to variable internal treatment. It is not suited to decay hazardous uses which require extensive cutting, shaping, boring, or resawing of the piece after preservation treatment. Good practice dictates that cut ends, bored holes and laying surfaces be given a heavy brush coat of preservative in decay hazard end uses for type I or II material.
