Jean Pierre Bill of Materials
LUMBER & PLYWOOD: All plywood must be intended for
marine or exterior use; interior grades are not acceptable.
The marine grade panel features higher grade inner ply cores,
while the exterior plywood grade cores may have voids not
apparent to the eye, and may also use cores made from woods
not as suitable for marine applications. In most cases, the
glues used in both the marine and exterior panels are the
same waterproof type, however, the decision to use exterior
panels in lieu of marine panels must lie with the builder,
considering the particular use of the panel in the boat and
the expected service. The letters A, B and C designate the
grade of the exterior veneers with A grade the best, etc.
Douglas-fir plywood is acceptable for all plywood, although
mahogany or other attractive veneers are preferable in many
instances as described in these instructions.
Lumber thickness is given as "nominal" except
where noted "net". Stock listed 2" thick will
usually finish from 1-1/2" to 1-3/4" thick. Widths
are given as net, however, nominal sizes can be used if it
suits the lumber species. All lumber sizes should be checked
to the work before purchasing wherever possible. Lumber
typical to the locale and proven in use in boats of similar
type can be used as long as the weight, strengths, and
characteristics are similar. Suitable boatbuilding woods
include white oak, mahogany (Mahog.- Philippine dark red,
American, or African types commonly used in boats), Sitka
spruce (SSP), Alaskan cedar, Port Orford cedar, Douglas-fir
(DF), longleaf yellow pine, apitong, and teak.
HULL MATERIAL LISTING: The following material listing
is an estimate of the materials required to build the basic
hull. The material listing is intended to serve as a general
guide only and should not be used to purchase materials until
the various options and alternatives have been checked to the
plans, to the work, and to the materials which may be
available in the area in which the hull will be built. The
listing may vary due to the amount of waste and other
variables that cannot be controlled. IMPORTANT: Do NOT
purchase materials from this listing without first reading
the instructions and checking the plans and instructions for
options.
