La Paz - Plywood Bill of Materials
MATERIAL LISTING: The following is an approximation
that can be used for hull cost estimates; it is not meant to
be used for buying materials without first checking the
instructions and plans for various options which will vary
the listing (especially with regard to planking panel sizes,
powering choices, laminated members, etc.), and to local
suppliers for what material sizes may be available. In other
words, each builder must make decisions as to how he will
build the boat and use materials, and then take off a listing
to suit. As a cost savings, materials should be grouped for
resawing to the sizes required. Plywood panel lengths are
given to cover the length of the vessel although stock panels
of the listed size may not be available. See previous herein
for options and alternatives.
PLYWOOD: All plywood should be at least AB Exterior or
Marine grade; Interior plywood is not acceptable. Douglas-fir
or Mahogany-type panels will suffice.
LUMBER: All lumber should be top quality, free from
defects, and of types proven in use in boats. Suitable woods
include vertical grain Douglas-fir, Alaskan cedar, mahogany
(including Philippine, Honduras, and African types), and good
quality Southern pine. Thicknesses given below are nominal
except as noted "NET". Widths are net. Total
lengths listed allow some overage for trimming, etc.

per schedule; take lengths directly from work.
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.
