Barracuda Aluminum
Bill of Materials
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 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. Note that if the length of the boat is varied, so too
will the material listing. Materials are listed for the basic hull
members only and do not include options, variations, interior members,
etc. Thus the listing will vary and not all members are necessarily
included - check the plans. 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.
