Design For Series Production
In some installations by using bayonet
type connectors the final electrical
hook up on the finished boat amounts
to simply joining the male/female
components. This type of installation
is commonly supplied on many of the
main engines used today and has con-
tributed substantially to improved in-
stallation productivity and reliability of
the engine's electrical system.
Plumbing Systems - Plumbing sys-
tems not unlike their electrical coun-
terparts have their own circuits. The
advanced production techniques em-
ploy pre-assembled plumbing trees, in
whole or in part to be later joined into
the complete network.
Subassembly installation outside of
the hull has proven to be most effi-
cient. In some installations plumbing
lines are attached to the underside of
cabin soles while they are upside
down before they are located on the
building jigs. Testing of a major por-
tion of the plumbing system can be done on the shop floor, leaks readily found and corrected with a minimum expenditure
of time and effort.
Again, it must be emphasized that accessibility to the various plumbing components in the finished product is
should be checked by a quality control inspector by actually trying to service the fittings.
The sub assembly examples given here also apply to many other components and systems that make up the complete
boat. Where optional items such as air conditioning, refrigeration, heating, etc., are offered to the buyer, the builder should
determine the most efficient installation sequence to minimize his costs and thus increase his competitiveness in the
Standardization - The production shop must be concerned with the high cost of carrying shelf inventory and loss of possible
production space for excess inventory requirements.
As the company's product line expands the requirement for various components going into the boat also increases putting
serious demands on warehousing space and cash flow. To offset this a diligent effort must be extended with every design
to make use of existing fittings, equipment, and components.
For an example of the latter, when laying out interior joiner work, existing drawers, door flaps, etc., can often be used in a
new design by making minor dimensional changes to the new layout.
The production shop that ignores the accrued benefits derived from standardization is ignoring a real profit opportunity.
Early FRP production building often took place in existing facilities, converted mills, warehouses, lofts, etc. Seldom did you
find the builder starting with a new plant specifically designed for production orientation.
The conversion of existing plants to FRP boat production was in most instances far from ideal. Workflow and material han-
dling was often encumbered by plant structure that could not be arranged. The low costs associated with labor and mate-
rial of the 50's and 60's made this approach to production tolerable. Some of the more progressive builders, however,
were quick to realize the advantage they could gain over competition by having an efficient plant layout.
