Rob Roy Bill of Materials
LUMBER: All lumber is "four quarter"
lumberyard stock, usually finished to 3/4" net
thickness. All widths are net, while all lengths allow for
cutting to fit. All lumber sizes should be checked to the
work before purchasing. When long lengths are not available,
splices may be made by a scarf joint of 1:12 ratio; full
length members are desirable for this hull. All lumber should
be free from knots, splits, and other defects. Mahogany
refers to "dark red" Philippine or central American
varieties. Spruce (Sitka), Douglas-fir, white oak, and
similar woods used for boat construction may be
substituted.
PLYWOOD: All plywood must be intended for marine use.
The most desiralbe material to use because of its lightweight
is okoume marine plywood.
