Rebel Tug - Aluminum Bill of Materials
ALUMINUM HULL MATERIAL LISTING: The following listing is to
serve as a general guide only for hull cost estimating
purposes; do not use for buying materials without first
checking the instructions and plans for various options (such
as differences due to changes in overall boat length and
powering methods which will vary each boat), 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. Thus the listing will vary and not all members are
necessarily included - check the plans. Note that if
tee's are not available, comparable sized angles can be
used instead, or the builder can build up comparable members
from flat bar (F.B.). Only marine alloy of the 5000- or
6000-series should be used. Common acceptable alloy
designations include 5052, 5083, 5086, 5454, 5456, and 6061.
For saltwater use, the 5086 is recommended except that
extruded shapes can be 6000-series. While full-length hull
plating panels can be formed by welding, single long panels
are preferable to performing this procedure. In any case, the
builder should check for plate or sheet size availability and
plan the material utilization for minimum waste. While
shorter members can always be butt welded to form long
members, a doubler plate is usually advisable behind or on
top of all such joints, lapping a considerable distance, and
being welded all around.
Does not include variations required between inboard
and outboard versions - see plans for options.
