Monte Carlo 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 used should be first grade, free from knots, shakes, checks,
or other defects. All widths are actual size. All thicknesses are
standard finished sizes, with 1" lumber being four quarters
material, usually finished to about 3/4". The exception is the
2' x 8" motor stringers which are standard finished size (1
1/2" x 7 1/2"). Grouping lumber and purchasing
"random-random" material to resaw to the required size will
result in considerable savings. 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, 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.

LUMBER:

In the "Frame" heading below deck beam lumber widths are not
listed. As described in the instructions many beams are segmented
across the boat. Using the shorter lengths will sabe considerable
lumber. The span of the bem is noted and the width required to make the
span can be obtained by using the "BT" template.

PLANKING: These instructions give several options for planking.
e.g., The inner veneers may be less expensive lumber than the outer
layer, and plywood can be used optionally on the bottom. Thus, the
following quantities are given in square footage of area to be
covered. The bottom is to be a total of 3/4" thick, the sides a
total of 5/8" thick. Veneer thickness will vary, depending on the
number of laminates used. If four laminations of veneers are used,
multiply the area to be covered by four to obtain the total square
footage required. Cold-molded construction results in considerable
waste; most add 20% to the square footage of the veneer to obtain the
total required. Mahogany, dark red Philippine, or Honduras is advised
for the outer lams.
-
Total area for both sides = 97 sq. ft.
-
Total bottom area = 128 sq. ft.
-
Total transom area = 13 sq. ft.
|
PLYWOOD: Minimum plywood grades are listed. Exterior (ext.)
grade plywood is specified, however, a full marine panel is preferable.
The letters "AB" designate the quality of the exterior
veneers, however "AA" panels are better. Douglas fir (DF)
veneers are acceptable, but mahogany or similar veneer surfaces are
more attractive.

-
Screws: Flathead wood type, bronze or hot dipped galvanized
-
1 1/4" #8 = 6 gross
-
1 1/2" #8 = 8 gross
-
2" #10 = 1 gross
-
3" #14 = 8 dozen
Nails: Ring type boat nails, bronze or Monel
-
1" #12 = 7 lbs.
-
1-1/4" #12 = 4 lbs.
Carriage Bolts: Bronze or hot dipped galvanized complete with
nuts and washers. Check lengths to work.
-
3/8" = 2 required at stem/keel junction
-
1/4" = 64 required for clips
-
1/4" = 40 required for frames
Adhesives: Epoxy adhesives are advised throughout the
construction. These may be an epoxy adhesive or epoxy resin. Epoxy
resins should be used with thickeners (microspheres and 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.
