Coronado - 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.

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.
