demand for multihulls has increased dramatically in the past
ten years. In particular, there is currently
an enormous interest in power and sail catamarans
both for leisure and service boats.
technical advantages of the multihull, combined with the wide
of the hull form in both commercial and charter use, have created
an unprecedented demand.
long history of multihulls started from Early Polynesians
would lash two large canoes together and sail from
one island to another. These people considered
the stability of a two-hulled vessel to be safer than that
of just one hull.
two centuries ago Polynesia was totally isolated from
rest of the civilized world, which was developing boats
as more traditional lines - single-hulled
keelboats, or monohulls.
the 1780s Captain Cook reported seeing beautiful boats
of up to 120 feet long, which
were built of carefully
painted and polished
wood. Exposure to the outside world brought European
diseases to these people, who had no immunities to
them. The populations
societies were ravaged and
these beautiful vessels disintegrate away. Only some

built the 25 foot catamaran Amaryllis.

Brown, a protégé of Piver, started
designing his own trimarans, called Searunners. He
designed them with
a wider beam for a safer, more stable

Soon Norman Cross, Lock Crowther, John Marples, and
allover the world was building
on the lessons that could be learned from
previous designs, both with trimarans and catamarans.

Brian Eiland - Wonderful combinations of sail & power Multihull Yachts - special mast-aft rig new motorsailor design is an innovative new sailing rig known as the DynaRig, which some of those virtues may be summarized as:
A cruising rig that is more aerodynamically efficient, which should enable you to get the same speed with less sail area, or more speed with the same sail area; delivers a clean leading edge for all the sails; allows the whole sail plan to be roller-furled away or deployed; allows the reefing of the sails without turning into the weather; divides up the total sail area into smaller manageable sizes; maintains its balance center (CE) with different sail combinations; produces less overturning moments; can be operated without leaving the cockpit. One single person could sail this fairly large rig from anchor up to anchor down. All the sails roller-furl, and the mainstaysail & the mizzen both can self-tack.
This is the official name of the multihulls designer
Norman A. Cross. His work, and its involvement in the
evolution of modern multihull design, is possibly one
of the greatest contributions by any single designer
of multihull sailing craft to date. In the actual WEB
site will be expanded to include all of his designs from
his first Cross 24 designed in 1963, to his Cross 78R
designed in the late 1980's.
Cross died August 14, 1990 at the age of 75. His experience
developed his engineering skills and love
for sailing translated to his prolific multihull
design work in a large range of boats from 14' to 78'.
a Norman Cross trimaran is unforgettable since the
fantastic seakeeping skills of his boats. Until
now his plans are supreme
and searched by thousands of builders.

passenger ferries operated at speeds of 16 knots
or less until recently, with long cycle periods to

transporters to provide twice as many trips as before and radically
reduced travel times for their passengers and cargo.
The introduction of the Incat ferries, and after by

operator, and Phillip Hercus, a boat designer
introduced these innovations
in design for fast, lightweight catamaran ferries.
BOAT AND BOAT BUILDING CAPABILITY
The marine industry, and the boatbuilding sector
in particular, represents one of the largest
sophisticated manufacturing and/or high value
added sectors. In addition, the sector has
a substantial regional presence having significant
potential for increased growth.
The boats industry is characteristically composed
of small and medium companies, largely by workmanship.
Dependent of skilled workforce, technologies and
know-how, with structures depend on planning, and
mainly of stability because boat construction is
a long time-consuming.
However the naval industry develops countless
sections in parallel, and generates countless resources,
being one of the most important sections for implementation
of an infinity of applications and diversifications
that understand from the tourism to the fishing,
and that involves productions of materials of a
wide range, from wood to motors.
It is indispensable in all the countries that
count with waterways, marine coast, and lakes,
of endowing of boatbuilding industry in conformity
with their potential.
The naval industry is important exporter, and
capable to generate a sustained development in
Several types of naval industries can be developed
with little capital, and to grow quickly, creating
productive regions and generating plenty structures

Research, Education and Services.
INDUSTRY STRATEGIES & PLANS
The Marine Industries sector
development within trade and innovation seeks continuous
key issues, opportunities
and support to improve growth of this priority industry
structured industry workshops and presentations
in various regional marine centers should
respond to trends, requirements and inquiries.
Departments of State, Development, Trade and
Innovation have to commission the Boating Industry
to analyze and summarize the position of
the marine industry. The research should identify
key issues in domestic and
international boat and boat building and
the growth and competitiveness of these industries.
The following priorities, has to be prioritized for
the Marine Industries Sector development:
¤ Boat and Boat Building Capability
¤ Training and Skills
¤ Technology and Innovation
¤ Marketing and Investment
¤ Regional Strategies
The development of marine industries requires
competitively priced and conveniently located infrastructure
form of commercial, industrial and boatyards and
areas offering access to boatlifts, slipways, dry-docks,
manufacturing and marine services capabilities and
To attain excellent quality, well-established infrastructure
throughout the regions with early planning for further
developments have to be established.
TECHNOLOGY AND INNOVATION
Marine industries are highly dependent of leading research
and development, innovation and technology uptake. Emerging
technologies in marine manufacturing, including fiber
composite boat building, are an essential component in
a globally competitive sector.
Marine Industries Sector in collaborative project
can develop and deliver a series of technology
programs for marine manufacturers. They have to introduce
and facilitate training and seminars for boatbuilders
covering new moldings techniques for composite builders
as infusion/closed and super forming of aluminum
developed from aerospace technology, for aluminum
Existing technologies such as CAD and 3-D design modeling,
fast tooling, fast prototyping, which have not been
widely adopted by smaller producers, also have to be
competitiveness is also a function of getting
quality products to market faster. The Marine
Industries have to accelerated product development
programs, specifically designed for boat builders.
Seminars on Supporting Manufacturing Techniques
training workshops to implement these procedures
also should contribute.
The incentive of local cargo boating and commercial
fishing sectors should attract a concentration
of first class marine suppliers to the marine
area. Products manufactured by marine suppliers
include electronics, including nautical and
navigational instruments, hydraulics, engines,
boilers, refrigeration, life-saving equipment,
deck machinery and a multitude of other equipment.
COMMERCIAL FISHING AND RECREATION
Commercial fishing is one of the oldest industries
areas and remains an important part of the marine
business for regional development. The commercial
fishing sector provides thousands of jobs in the
area and accounts for gross annual sales and exportation.
