Barracuda Plywood version
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.
All lumber should be top quality, free from defects, and of
types proven in use in boats. Suitable woods include Sitka
spruce, vertical grain Douglas-fir, mahogany (including
Philippine, Honduras, and African types), and comparable
woods of good quality. Thicknesses are nominal except as
noted "NET". Widths are net except 2" thick
nominal members may be of nominal width also. Total lengths
allow some overage for trimming, etc., but the breakdown for
number of pieces should be checked to the plans and matched
to lengths of stock available.
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.

Adhesives: Epoxy adhesives are advised
throughout the construction. These may be an epoxy
adhesive or epoxy resin. Epoxy resins should be used
with thickeners (silica or equal) per the
instructions with the resin and/or thickening agent.
Due to the noted options, the amount required is
difficult to estimate. Start with a gallon container
of epoxy and after use you will be better able to
estimate the total amount required.
