Cabin Skiff Bill of Materials
DO NOT PURCHASE ANY MATERIAL UNTIL YOU READ THIS SECTION.
The following list of materials is intended to be a general guide only. Before
ordering any materials, the text and plans should be checked for possible
options. All lumber listed as 1" stock is to be standard "lumberyard
four-quarter" material which when finished may vary to somewhat less or
slightly more than 3/4" in thickness. All widths are NET and all lengths
allow for cutting to fit. Grouping lumber and purchasing random-random material
to resaw to the required size will result in considerable savings. All lumber
used should be first grade free from shakes and knots. Although mahogany (dark
red Philippine type) is called out in the listing, lumber typical to the locale
and of similar types and weights may be substituted. All plywood (PW) is to be
marine (MAR) or exterior (EXT) grade. The marine-type is preferable as the
inner cores are solid and thus the panel has more structural integrity.
Douglas-fir (DF) is satisfactory with the quality of the exposed faces of the
veneer being designated by the letters "A" or "B". The
"AA" grade panels are always preferable, however, "AB"
grade is acceptable. All plywood should be a minimum of three plies. All
fastenings should be bronze or hot dipped galvanized ferrous metal. Brass
fastenings are not advised nor are the electroplated screws commonly sold in
hardware stores. All screws are to be of the flat head type intended for wood.
All nails are of the ring-type nail common to boat construction. Unless
otherwise specified, all wood-to-wood joints are to be glued with a waterproof
or highly water resistant glue such as plastic resin, resorcinol, epoxy, or
other equivalent type used per the manufacturer's instructions regarding
temperature, clamping requirements, curing time, and mixing method.
Abbreviations used in the following are: DF = Douglas-Fir; Mahog. = Mahogany;
PW = Plywood; MAR = Marine; EXT = Exterior.
