Catamarans: The Multi-Hull Boats Revolutionizing Marine

History and Development

Catamarans have been around for thousands of years but modern catamarans were first developed in the 1950s when sailing and speed became a priority. Early Polynesian settlers in the South Pacific were the first to design multihull boats out of bamboo and timber over 2000 years ago. These early were often simple rafts or coastal trading vessels that could transport more cargo than single-hull boats.

In the 1950s as fiberglass production became widespread, naval architects began experimenting with Catamarans designs that emphasized speed over cargo capacity. Early racing catamarans from Hobie and Clipper were proving they could sail faster than monohulls. Through the 1960s, lightweight but high-performance catamarans set world sailing speed records. Their double-wide hull design offered over twice the waterline length of an equivalent monohull for increased hull speed potential.

Major Advances in Design and Construction Methods

As construction methods advanced, naval architects were better able to refine the stable hull forms needed for high-speed planing. Adopting the V-shaped hulls of early hydrofoils, multihulls began to lift up and skim above the waves rather than plow through them. Carbon fiber and improved core materials kept hull weights low while also allowing double chine or wave-piercing designs. Suspended bridges and wider sponsons further increased stability at rest and while heeled over.

Today’s premier catamaran shipyards like Outremer, Lagoon and Fountaine Pajot produce vessels up to 150 feet long using computer-optimized design, vacuum bagged infusion molding and rigid aluminum grid structures. Their multihulls offer performance, cruising amenities and seakeeping unmatched by production monohulls of similar size. Even very large charter and expedition catamarans in the 60-100 foot range have proven themselves in bluewater rallies and circumnavigations.

Advantages of Increased Speed, Space and Stability

Modern performance cruising catamarans have maximum speeds of 25-30+ knots but maintain average speeds under power of 18-22 knots. With large fuel-efficient diesel engines they offer transocean cruising range equivalent to monohulls but reduce passage times dramatically.

Their wide beam yields maximum interior volume for a given waterline length. With over 300 square feet more deck and cabin space on average, they offer all amenities of stationary homes including large salons, master staterooms, multiple heads and al fresco dining. Their stable pontoon hulls make standing, walking and daily activities easier at sea versus the constant motion of a monohull. Wide side decks safely access all vessel systems and generous cockpit areas become the focal point for entertaining.

Drawbacks addressed with improved seakeeping designs

Early criticisms of them as unsuitable for offshore conditions due to their initially lower stability have been countered with stiffer hull and bridge designs. Modern hullforms featuring fuller bows, concave shearlines, shallower underwater sections and overall round bilge sections make them among the most seakeeping boats available for bluewater voyaging. Although a heavy following sea or surf may cause skipping, the stability provided by their twin floats plus wide beam ensure they can largely weather conditions that would roll or pitch a monohull dangerously. Dual rudders and engines with excellent maneuverability also make them as handy as traditional sailing yachts.

Growth in Popularity for Cruising, Racing and Charter Use

Large sailing have become the preferred choice for circumnavigators, world record holding cruisers and Vendée Globe racers because they reduce voyage times and increase accommodation comforts compared to monohulls. While still limited for daysailing or living aboard in small marinas, their popularity is exploding in the Caribbean, Mediterranean and South Pacific charter markets. Several builders now offer solar-electric variants ideal for coastal cruising or as luxury day boats for bareboat or crewed charters.

Racing continue evolving at an astonishing pace, maxing out the boundaries of hull design and foil assisted foiling. From 18 to 60 feet they regularly beat monohull speed records. Even the America’s Cup which was once the sole domain of monohulls, now allows multihull as competitors are realizing the performance potential they offer.

The Future Remains Bright

As builders hone systems integration, offshore stability, shallower drafts and ease of handling, multihull ownership outside the charter industry will grow steadily. Like motor yachts proved decades ago, once catamarans achieve the build quality, engineering and comfort levels of luxury land homes, they will become the preferred boating lifestyle choice for many. Those who experience living aboard will unlikely want to return to the swinging bunks and confined quarters of a monohull no matter the tradition. For speed, extended cruising range, interior volume or as stable heavy-weather boats suited to coastal and offshore passages worldwide, the multihull catamaran is without peer and poised for continued primacy in the decades ahead.
