Robert Barnwell Roosevelt , uncle of American President Theodore Roosevelt , also built a proa at about the same time. He used it sailing from Long Island. It was significantly different but equally creative, and at 50 feet 15 m , Yacht Builders Thailand English Yacht Builders Thailand English Yacht Builders Thailand English much longer. From his article in The Rudder , it appeared the main hull of Roosevelt's proa was an open 4-foot 1. The mast was a bipod arrangement with both masts stepped to windward, with a boomed, balanced lugsail suspended from the apex.

It is not Yacht Builders Thailand English clear if the boat predated Munroe's proa. Since Munroe wasn't aware of the raking mast, his model used two daggerboards set Yacht Builders Thailand English Yacht Builders Thailand English fore and aft of the mast, which would allow adjustment of the center of lateral resistance to provide helm balance. From the Builders Yacht Thailand English drawings, it appears the mast is higher as well, allowing a larger sail.

The sail design also changed, with the upper spar now Yacht Builders Thailand English being slightly longer than the upper edge of the sail, and projecting past the apex slightly to allow the apex to be attached Thailand English Builders Yacht Yacht Builders Thailand English Yacht Builders Thailand English to the hull.

The sail was loose footed, with the boom attached to the upper spar near the sail apex, and to the clew of the sail.

His article in a issue of The Rudder included more details on the construction of his second proa. A Yacht Builders Thailand EnglisYacht Builders Thailand English h book of sailboat plans published by The Rudder includes the following specifications for the proa:. From the drawings, the distance from the center of the main hull to the center of the aka is about 12 feet 3. Western designers often feel the need to tinker with the proa. They are attracted by the minimalist nature and amazing speeds that proas are capable of they may still Yacht Builders Thailand English be the fastest sailboats per dollar spent for the home builder but they often want the proa to do more; adding cabins, different sailing rigs, and bidirectional rudders are common changes made.

James Wharram was greatly influenced by the Proa design. For example, unconventional boat and Yacht Builders Thailand English Yacht Builders Thailand English yacht designer Phil Bolger drew at least three proa designs; the smallest one 20 ft has been built by several people while the Yacht Builders Thailand English Yacht Builders Thailand English larger two, including his Proa 60, have not been built. For additional examples, see here. The terms ama and aka have been Yacht Builders Thailand English Yacht Builders Thailand English adopted for the modern trimaran.

Since trimarans are generally designed to sail with one ama out of the water, they are similar to Yacht Builders Thailand English Yacht Builders Thailand English an Atlantic proa, with the buoyant leeward ama providing the bulk of the stability for the long, relatively thin main hull. Some modern Yacht Builders Thailand English Yacht Builders Thailand English proa designers have borrowed trimaran design elements for use in proas. Trimarans often have main hulls that are very narrow at the English Yacht Builders Thailand waterline, and flare out and extend over a significant portion of the akas. This topheavy design is only practical in a multihull, and Yacht Builders Thailand English Yacht Builders Thailand English it has been adapted by some proa designers.

Notable examples are the designs of Russell Brown, a boat-fittings maker who designed and built Yacht Builders Thailand English his first proa, Jzero , in the mids. He has created a number of proa designs, all of which follow the same theme. One Yacht Builders Thailand English of the design elements which Brown used, and a number of other designers have copied, is the lee pod. The akas extend Yacht Builders Thailand English Yacht Builders Thailand English past the main hull and out to the lee side, and provide support for a cabin extending to the lee of the main hull.

This is similar to the platform extending to the lee on some Micronesian proas. The lee pod serves two purposes�it can be used for bunk space or storage, and it provides additional buoyancy on the lee side to prevent a capsize should the boat heel too far. Crew can also be moved onto the lee pod to provide additional heeling force in light winds, allowing the ama Yacht Builders Thailand English to lift under circumstances when it would not otherwise.

The Jzero also used water ballast in the ama to allow the righting moment to be significantly increased if needed. One of the issues Western designers have with the proa is the need to manipulate the sail Yacht Builders Thailand English Yacht Builders Thailand English when shunting.

Even Munroe's early sails discarded the curved yards of the traditional crabclaw for the more familiar straight yards of Yacht Builders Thailand English the lateen and lug sails.

Munroe's designs likely lacked the tilting mast because he was unaware of it, but many designers since Yacht Builders Thailand English have use a fixed mast, and provided some other way of adjusting the center of effort. Most sailboats are designed with the center of effort of the sails slightly ahead of the center of area of the underwater plane; this difference is called "lead.

Thus the center of effort of the sails needs to also be well forward, or at least needs to have a sail which is well forward which can be sheeted in to start the boat moving, allowing the rudders to bite and keep the boat from heading Thailand Builders Yacht English up when the entire sail area is sheeted in.

Jzero, for example, and all of Russell Brown's other designs, use a sloop Yacht Builders Thailand English rig and hoist a jib on whichever end is the current "bow". Other designs use a schooner rig for the same effect. One Yacht Builders Thailand English of the more practical rigs for small proas was invented by Euell Gibbons around for a small, single handed proa.

This rig Yacht Builders Thailand English was a loose footed lateen sail hung from a centered mast. The sail was symmetric across the yard, and to shunt, what was previously the top end of the yard was lowered and became the bottom end, reversing the direction of the sail. Proa enthusiast Gary Dierking modified this design further, using a curved yard and a boom perpendicular to the yard. While a proa is fairly efficient Yacht Builders Thailand English Yacht Builders Thailand English at minimizing the amount of wave drag and maximizing stability, there is at least one way to go even further.

The use of underwater foils to provide lift or downforce has been a popular idea recently in cutting-edge yacht building, and the proa is not immune Yacht Builders Thailand English Yacht Builders Thailand English Yacht Builders Thailand English to this influence. The Bruce foil is a foil that provides a lateral resistance with zero heeling moment by placing the foil to either or both of the leeward and the windward sides, angled so the direction of the force passes through the center of Yacht Builders Thailand English Yacht Builders Thailand English effort of the sail.

Since proas already have an outrigger to the windward side, a simple angled foil mounted on the ama becomes a Bruce foil, making the already stable proa even more stable. Bruce foils are often combined with inclined rigs, which results in a total cancellation of heeling forces.

Inclined rigs are also well suited to the proa, as the direction of incline remains constant during shunting. Another use of foils is to provide lift, turning the boat into a hydrofoil. Hydrofoils require significant speeds to work, but once the hull is lifted out of the water, the drag Dutch Sailing Yacht Builders List Ltd is significantly reduced. Many speed sailing designs have been based on a proa Yacht Builders Thailand English type configuration equipped with lifting foils. In a non-traditional variant, first seen among Western yacht racers, the "Atlantic proa" has an ama Yacht Builders Thailand English Yacht Builders Thailand English which is always to the lee side to provide buoyancy for stability, rather than ballast as in a traditional proa.

Because the Atlantic Yacht Builders Thailand English ama is at least as long as the main hull, to reduce wave drag, this style can also be thought of as an asymmetric catamaran that shunts rather than tacking.

Newkirk's designs are primarily trimarans, and the Atlantic proa's buoyant outrigger follows naturally from a conversion of a trimaran from a tacking to a shunting vessel.

Other proa designers blur the lines between Atlantic and Pacific style proas. The Harryproa from Australia uses a long, thin hull to lee, and a short, fat hull, containing the cabin, to windward. This would normally be more like an Atlantic proa, but the rig is on the lee hull, leaving it technically a Pacific design. This and other similar proas place the bulk of the passenger accommodations on the ama, in an attempt to make the vaka as streamlined as possible, and put much of the mass in the lee side to provide a greater righting moment.

Perhaps the most Yacht Builders Thailand English Yacht Builders Thailand English Yacht Builders Thailand English extreme variants of the proa are the ones designed for pure speed. These often completely discard symmetry, and are designed to sail only in one direction relative to the wind; performance in the other direction is either seriously compromised or impossible. This design has been considered by others as well, such as the Monomaran designs by "The 40 knot Sailboat" author Bernard Smith, and these designs been called Yacht Builders Thailand English Yacht Builders Thailand English Yacht Builders Thailand English 3-point proas by some, a reference to the 3 point hulls used in hydroplanes.

Crossbow II was a "slewing" catamaran, able to slew Yacht Builders Thailand English her hulls to allow clear airflow to her leeward bipod sail. Although the hulls appeared identical, the boat had all crew and controls, Yacht Builders Thailand English Yacht Builders Thailand English Yacht Builders Thailand English cockpit etc. In March , two new sailing speed records were set by vehicles based on the proa concept, one on land, and one on the water. On March 27, , Richard Jenkins set a world wind-powered speed record, on land, of The Greenbird is based on Yacht Builders Thailand English English Thailand Builders Yacht a one-way proa design, with a long, thin two-wheeled body with a third wheel to the lee acting as an ama.

The aka, Yacht Builders Thailand English which is in the shape of a wing, provides a significant amount of downwards force at speed to counter the heeling force generated Yacht Builders Thailand English by the high-aspect wing sail.
