Boat Design          





The naval sector is one of the oldest transport sections and wherein more progresses were incorporated among the vehicular segment. Practically a revolution since the sixties.

The incorporation of the multihulls, high performance, design assisted by computers, composites, simulators, software, hydrodynamic, aerodynamics, motors and propulsions, commands and electronics. In forty years a new generation of concepts took form, even whether the traditional boats still coexist and maintain its own space and the classic absorbs a growing public. That is a sector where the tradition and the modern live well together.

However the technological evolution, design and engineering seems only to have operated the beginning of a revolution where new concepts are being patented the whole time.

Six months don't pass without a new revolutionary concept is introduced by the naval industry.

On this last year, a trimaran with hydrofoils crossed the channel "de la Manche" fastest than an airplane, counting the times of take-off and landing.

Being the naval sector very extensive and counting with vast industry activities, it involves normally small industry and series, that allows incorporate technological progresses quickly. It is the priority section of composites employment, new metals, plastics, electronics, inks, varnishes, rescue material, diving material, insulating, woven and processes. The engineering R & D is applied directly, once most of the boats are built in a unitary way.

The design and development is accomplished allover the world by small countless architecture and engineering offices, composing countless tendencies and principles.

The naval sector turned a great laboratory of trends, design, materials and studies.

The boat industry has innumerous sections that will be referred by means of annexed directories to this WEB page.

From new aluminum alloy light boats to big composites megayachts the boat industry has an enormous diversity.

Introducing the main trends and researches, new materials and process, this section will support boat industry development, reported as one of the first worldwide industry as the main targets of "factory of factories" portal as well as small and medium enterprises characteristics.








Since the Boat Design concept was first visualized, boat and yacht designs have entered a period of modern computer design methods, which are random and interactive processes that may consist of stages or general trials.

A large amount of refinements were made over time, the features of random and interactive design methods have in effect transformed design process.

The modern design methods are capable of producing suitable designs; they are expected to produce optimum ones. This is because the random process requires a great deal of design time and thus designers have substantial time to explore all potential designs. Moreover, being able to recognize the effects of slight modifications on the design at once, designers may alter every design requirements while concentrating on a particular design aspect or overall aspect.

In the computer age, boat and yacht designers have advantages from computer technology as a tool for reducing tedious calculations.

State-of-the-art innovation is represent by the development of an integrated 3D modeling and Computer-aided Design (CAD) method for boat designs, which combines all distinctive boat design software modules in a single system.

This state-of-the-art design method captures the features of modern design methods form; from paper and pencil sketches (by means of scanners) to computer screen modeling, and designers are able to recognize the effects of subtle modifications on the design.

This random process also makes available a great deal of design time and thus reduces the exploration efforts, which results in optimum designs. Less difficulties of data redundancy, inconsistency, and flexibility structure are obtained in addition

The 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.

The technical advantages of the multihull, combined with the wide acceptance of the hull form in both commercial and charter use, have created an unprecedented demand.







The 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.

Until two centuries ago Polynesia was totally isolated from the rest of the civilized world, which was developing boats as more traditional lines - single-hulled keelboats, or monohulls.

In 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 and societies were ravaged and these beautiful vessels disintegrate away. Only some native activity in the Hawaiian Islands the catamaran design remained.

Then, in the late 1870s, Nathaniel Herreshoff designed and built the 25 foot catamaran Amaryllis.

At 1952 -- in England, the Prout brothers designed a U shaped hull, instead of the V shape that had preceded it, and they included centerboards. Now the boats would actually tack.



They became popular in Europe because of their speed and comfort, and the long slow process of design evolution took a step forward.

By the late 50's there were quite a few sailors experimenting with new designs and building materials. With the advent of fiberglass, resins, and marine plywood these boats could be built light and strong.

Jim Brown, a protégé of Piver, started designing his own trimarans, called Searunners. He designed them with a wider beam for a safer, more stable platform, along with other modifications. Soon Norman Cross, Lock Crowther, John Marples, and innumerable designers from allover the world was building on the lessons that could be learned from previous designs, both with trimarans and catamarans.

These designers realized the requirements for detailed, precise plans, and for the designer to be involved with the builder from the beginning of construction in order to assist to create a safe, fast, comfortable boat.








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.

Norman 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'.

Experimenting 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.

The catamaran hull form is exceptionally good for cargo transport, and consequently catamarans make excellent vehicle ferry platforms, particularly for high-speed services.

Catamarans have spacious wide decks, which are not only appropriate for a large number of vehicles, but also allow vehicles to drive on, and drive off. Vehicle decks are high above the water, independent engine rooms and very high stability margins; catamaran vehicle ferries are particularly safe.

The passenger ferries operated at speeds of 16 knots or less until recently, with long cycle periods to unload and load passengers and vehicles. In the beginning of 1990s, large catamaran ferries of aluminum start operating on ferry routes around the UK, and then on other ferry routes around the world.

These ferries operating at twice the speed of conventional ferries, was first made by Incat in Hobart. With very short ‘turnaround’ times, allowing 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 others competitors, generated a revolution in ferry transport, which continues today. Incat and other companies like Austel established a new boatbuilding industry in Australia that dominates world markets for high speed ferries.

The innovations in service provided to the owners and operators of the ferries and Incat’s ferries innovative design features have been successful in world markets, transforming the ferries industry.



Incat’s high speed catamaran ferries developed the concept wave-piercing design that allows the twin hulls with sharp bows to ‘pierce’ the waves rather than riding over them. The collaboration between Robert Clifford, a boatbuilder and ferry operator, and Phillip Hercus, a boat designer introduced these innovations in design for fast, lightweight catamaran ferries.





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 numerous areas.

Several types of naval industries can be developed with little capital, and to grow quickly, creating productive regions and generating plenty structures of employments.

Direct connected areas are: Ports, Marine Supply, Boatbuilding and Boat Repair, Tourism, Recreation, Research, Education and Services.






The Marine Industries sector development within trade and innovation seeks continuous key issues, opportunities and support to improve growth of this priority industry sector.

Conducting structured industry workshops and presentations in various regional marine centers should respond to trends, requirements and inquiries.

The Departments of State, Development, Trade and Innovation have to commission the Boating Industry Associations 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:

¤ Regulations
¤ Boat and Boat Building Capability
¤ Infrastructure
¤ Training and Skills
¤ Technology and Innovation
¤ Marketing and Investment
¤ Regional Strategies





The development of marine industries requires competitively priced and conveniently located infrastructure in the form of commercial, industrial and boatyards and areas offering access to boatlifts, slipways, dry-docks, manufacturing and marine services capabilities and deepwater berths.

To attain excellent quality, well-established infrastructure throughout the regions with early planning for further developments have to be established.





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.

The 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 builders.

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 introduced.

Manufacturing 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 and 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 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.
