Discussion:
For centuries this has been the favored wood for boat building, especially
for decks. The oily, waxy surface repels water rather than absorbing it.
The wood does not corrode metal fasteners and remains relatively stable
despite repeated wetting and drying. During World War II, with mostly
Southeast Asia (the only source) cut off, the allies encouraged the widespread
development of plantations in Africa and Latin America. These plantations
are now being harvested.
