ASSEMBLING A STEEL OR ALUMINUM
Over the past thirty years the Bruce Roberts Design team,
lead by chief designer Bruce Roberts-Goodson, has produced hundreds of designs and
developed numerous building techniques from which over 20,000 boats have been built world
wide, including power and sail pleasure boats, commercial and fishing boats. From this
they have gained a depth of knowledge and experience allowing them to participate in
advanced computer development for metal boats which has resulted in a range of designs to
50 meters and of which the steel designs are now all available in "flat
pack" steel STEEL OR ALUMINUM PLANS & CUTTING FILES form for delivery world wide. All steel is "Grade A"
(St.44) with Lloyds certificate and cut on an "NC" driven plasma-oxygen cutting
With the advent of this computer assisted three dimensional
development it has become possible not only to offer the popular range of Roberts stock
designs but to include any steel design at a modest additional cost for the computer
development. Radius chine STEEL OR ALUMINUM PLANS & CUTTING FILES are available as well as single and multi chine packages.
These STEEL OR ALUMINUM PLANS & CUTTING FILES appear to provide the elusive link between computer-aided design and the latest
fabriCATAMARANion techniques. Individuals and shipyards, particularly small enterprises can now
benefit from modern cost-effective methods without major investment. With these
techniques, you can obtain millimeter accuracy with outstanding surface finish. To quote
from one builder, Roger Lasham, building a Coastworker 30 in the UK, "I had completed
the bottom plating which was only tack welded in place, yet when it rained overnight and
the wind pulled the tarp aside allowing water to collect in the bow, it did not leak away
so accurate was the fit".
TYPICAL SPRAY STEEL OR ALUMINUM PLANS & CUTTING FILES
Looks simple! This STEEL OR ALUMINUM PLANS & CUTTING FILES saves hundreds of hours of
making patterns and cutting metal....See below.
Steel STEEL OR ALUMINUM PLANS & CUTTING FILES only require semi skilled labor for assembly and
all steel plates, excepting 3mm, are shot blasted and primed with "Sigmaweld-mc"
zinc rich primer which is especially formulated to allow the builder to weld the plates
without destroying the adjacent prime coating. Another feature of this weld primer is that
it does not give off toxic fumes nor is there any weld "splatter". As each STEEL OR ALUMINUM PLANS & CUTTING FILES
is "computer developed" and the parts are all nestled including all the plating
so that you can easily assemble the hull, deck and superstructure in a very short time
compared to conventional building and THERE IS NO WASTAGE. All windows, doors, scuppers,
prop and rudder tube holes are cut out and a pre-cut building cradle is supplied.
Bruce Roberts organization is able to develop any existing design into a steel STEEL OR ALUMINUM PLANS & CUTTING FILES or
provide modifications to an existing design to be incorporated in a STEEL OR ALUMINUM PLANS & CUTTING FILES. They offer a
worldwide service and a special facility for builders and boatyards in developing
countries where STEEL OR ALUMINUM PLANS & CUTTING FILES can be supplied tack welded or fully welded and come with full
technical backup and access to the latest building techniques and designs. Labor saving
can be as much as 75% on conventional hull building times.
These metal STEEL OR ALUMINUM PLANS & CUTTING FILES are produced in such a manner that even an
experienced builder will save many hours on the preparation work because the plates,
frames, longitudinal and stringers and further necessary parts for the hull and
superstructure are supplied pre-cut and accurate. NO TRIMMING IS REQUIRED. All the parts
fit perfectly. On radius chine STEEL OR ALUMINUM PLANS & CUTTING FILES, the radius panels are rolled to the correct radius
and you will only need to trim the edges after you have installed the rest of the hull
plating which, does not need trimming. All plates have marking lines for positioning of
frames, etc. and all plates are numbered and come with clear instruction and part drawings
showing all items. Maximum plate size 6 x 2 meter. Metal STEEL OR ALUMINUM PLANS & CUTTING FILES are available in STEEL or
