from about 12 ft (3.7 m) up to 23 ft (7.0 m) (Stiletto). The smaller boats are often intended to sail and race with one sailor aboard, those boats usually have no jib sail and are often 14 or 17 ft (4.3 or 5.2 m) long and about 300 lb (140 kg). The width of the boat (the beam) is ideally a bit more than 1/2 the hull length, i.e. the 20-foot (6.1 m) Supercat had a 12-foot (3.7 m) beam and is one of the very highest performing catamarans, however a 12 foot wide boat needs to be completely disassembled for transport by trailer on public roads, that greatly limited sales and popularity of the
Supercat 20, as well as the Tornado with its 10-foot (3.0 m) beam. Most Beachcats were limited to a maximum 8-foot (2.4 m) beam but in a peculiar twist of fate, in the US when the trucking union requested permission to drive faster on highways than the then 55 mph (89 km/h) limit, the Federal government instead raised the maximum trailerable width to 8'6", enabling all trailerable boats to be designed 6 inches wider. Boats from the mid-1980s were often then built to the new width, most older designs were not updated however as they were considered 'one designs' and remained unchanged. The mid size beachcats intended for two persons or more will usually weigh about 400 lb (180 kg) (typical 18 foot). Handling beachcats on the beach is commonly aided using 'beach wheels', essentially an aluminum pole as an axle with two large lightweight tires that do not sink into the sand enabling the boat to be rolled about by one or two persons.

production. There was also the international sailing association design criteria for racing cats organized into four letter classes, A, B, C and D classes. Those classes gave agreed upon basic dimensions that any would be racers could design to and compete evenly by class. Most designs had two hulls connected by two aluminum beams and use a cloth mesh net as the "deck" aka "tramp" or trampoline-The A-cat became popular and currently is exploring the move into higher performance via foiling. The 20 ft (6.1 m) Tornado was designed in 1966 as a B cat, it is still considered one of the fastest designs. In 1984 the
Tornado became an Olympic class for two sailors. The hulls once were laminated of wood, later fiberglass and currently autoclaved carbon/epoxy is used on the fastest boats. The hull shape works so well it inspired several easier to handle production boats, including the

skeg and daggerboard options, Hobie created a catamaran that could easily sail on and off the beach through the surf. The brilliance of the initial Hobie design was the combination of the asymmetrical hull design with the smaller, surf "friendly" layout. Without dagger boards but with a large sail area to weight ratio (the "16" weighed 325 lb (147 kg) at its inception and, with over 350 sq ft (33 m) of sail), the initial Hobie designs were able to sail into and out of heavy surf safely. The asymmetric hulls reduced lateral drift which made dagger board-dependent designs more difficult to handle in unfavorable winds or over extended shallow areas where dagger boards could not be deployed.

Whaler "SuperCat 20". The influence of the
Tornado as an Olympic class beginning in 1984 cannot be underestimated in the emphasis placed on symmetrical, dagger board based models. The Tornado, with its estimated thirty knot top speed, and Olympic panache, contributed to the continuance development of faster and faster "beach cats", which, theoretically, could sail in and out of the surf, but in reality, were much more adept at one design racing. Hence, the development of the F (for Formula) 18 class certification.

traditional catamaran sail plan. The design's chief limitation was its weight of over 500 lb (230 kg) with approximately 300 square feet (28 m) of sail area. The design was a traditional design with dagger boards and a hard deck. By comparison, the Aqua Cat 12 weighed 160 lb (73 kg) and could easily be carried by two people, and the mast raised by one person.

buoyancy, resist this tendency, allowing more forward weight balance in heavier air (wind speed), although
Prindles are still capable of pitch-poling given the right combination of forward weight, wind and sea conditions. Although out of production, the Prindle 16 is still in good supply on the used market, but the asymmetrical hulled 18s are rare.
425:
After the Hobie 14/16 and
Prindle 16/18 "era", beach cat manufacturers increasingly moved away from the asymmetrical designs which moved easily on and off the beach, and focused on theoretically faster symmetrical designs, including the aforesaid Prindle 19, the Hobie 18, the Nacra 5.2 and the Boston

Prindle moved into the classes production in the early 1990s, with the development of the
Prindle 19, a well designed, fast and balanced ship. The Prindle 19 class continues to grow but is at best a borderline "beach cat", with more of an emphasis on hydrodynamically linear hull design and the use of

In the United States, Art Javes designed and marketed an early fiberglass catamaran sailboat, the Aqua, in 1961. The Aqua was a 12-foot-long fiberglass hulled cat, which featured two flat-bottomed, foam filled, symmetric fiberglass hulls. These hulls were connected with aluminum tubing that supported

Catamarans use their wide form to get stability while keeping wetted area low with just 2 narrow hulls in the water. As the windspeed increases, the sailor(s) usually can 'trapeze' off the side using their weight to minimize the boats heeling and enabling higher boat speed. Beach cats range in length

Prindle and Hobie were by no means the only beach cats in the early 1970s. Deviating from the raised platform and asymmetrical design typified by the Hobie 14 and 16, and the asymmetrical designs with the cross members set at deck level, as typified by the Prindle, new designs sprang up between

The
Prindle Cat, introduced in 1972, sought to improve on the basic Hobie design by increasing the forward buoyancy with an almost vertical sheer (a trend that is currently the vogue in forward design, see, the 2011 Hobie "Wild Cat" F18 design and most of the current cruising designs from Fountaine

The original Aqua cat 12 was modified to an improved Aqua Cat 12.5 and is also available as an Aqua Cat 14 Catamaran which features upturned hulls and is available in an easier sailing resort model. The 14 ft (4.3 m) model uses small keels to replace the dagger boards found on the smaller

The resulting and nearly ubiquitous Hobie is now the most recognized beach cat of the last thirty years. It combines the structure of the earlier Aqua with the asymmetrical hull design of the

In 1961, Hobie Alter was selling surfboards at an Anaheim boat show where he met Art Javes and the Aqua Cat 12. Shortly after this boat show, Hobie entered the catamaran business as well. The Hobie Cat was introduced in 1965 and borrowed some features from the Aqua Cat. The fledgling catamaran

One early beachcat, the Pacific cat, appeared in 1960 in California. The Pacific cat was designed by Carter Pyle and was first built in 1960. It was slightly smaller than 19 ft × 8 ft (5.8 m × 2.4 m), and was a solid fiberglass catamaran with a solid core deck and

During the 1950s several catamaran designs were built in Europe and America. Construction styles and materials varied. Manufactured beachcats first came into style in the 1960s, with several popular designs. The Aqua cat is a good example of one of the early 1960s catamarans that is still in

364:. The Hobie Cat was the only design of the early three that did not use dagger boards, although now it offers designs with dagger boards and skegs. When running in and out of the surf, the lack of dagger boards or center boards makes "beaching" almost effortless.

Photos of the Pacific cat demonstrate that it was adept at handling the daunting Pacific coast surf, probably due to the momentum it carried even with the limited (for the time) sail plan. Pacific cats were made by Newport Boats / Mobjack Manufacturing.
