Astus 20.1
The Astus 20.1, built by Astusboats, is a 20 ft (6.1m) trimaran dinghy aimed at family day sailing, though its cabin offers basic cruising capability. Its multihull design offers speed and stability. Construction The Astus 20.1 is built in glass reinforced polyester (GRP) covered with white gelcoat. The cockpit floor has a honeycomb core, offering rigidity and durability. The floats are mounted on telescopic tubes and can be extended or folded on shore or on the water, making it possible to use narrow split ways or monohull marina berths. Cockpit: The cockpit of the Astus 20.1 is large enough to accommodate 7 adults. The cockpit floor is flat and free from centreboard well or any other gear. The cockpit coamings offer good protection for children. Spars: The Astus 20.1 mast has one pair of spreaders. The main sail attaches to a boom. Sails: The Astus 20.1 is equipped with a dacron furling jib and dacron mainsail as standard. The mainsail is fully battened and has one reef as ...

Astusboats
Astusboats is a French trimaran manufacturer based in Brech. The trimarans produced by this shipyard are designed by Stéphan Vallet, and have the characteristic of being trailerable due to the telescopic tubes in which the floats are mounted (except for the 14.1 model which is narrow enough to be trailed with the floats in place). Product line The current product line is: * Astus 14.1 (2007) * Astus 16.1 (2006) * Astus 18.1 (2010) * Astus 20.1 (2005) - discontinued * Astus 20.2 (2009) * Astus 22.1 (2008) See also * List of multihulls Types * catamaran = two symmetric hulls * proa = two asymmetric hulls, reverse-shunting (interchangeable bow/stern) * trimaran = three hulls * quadrimaran = four hulls * pentamaran = five hulls Pre-modern Austronesian * ʻalia * Amatasi * B ...

Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian terms f ...

Multihull
A multihull is a boat or ship with more than one hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions. Sailing multihulls Counter-intuitively, it is unhelpful to think of the design progression to be "1-2-3", namely monohull - catamaran - trimaran; rather, it is "1-3-2". A sailing trimaran is, in effect, a modified monohull with lightweight outrigger hulls (or "amas") for stability instead of a heavy deep keel; so it follows that a sailing trimaran will be lighter and faster than a sailing monohull. A sailing trimaran will have a centre hull that may comprise up to 90% of total hull volume, and 95% of total deadweight. A sailing trimaran at rest will have both amas out of the water and, when heeled, will only ever have one of the amas immersed. A ...

Gennaker
A gennaker is a sail that was developed around 1990. Used when sailing downwind, it is a cross between a genoa and a spinnaker. It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa. The gennaker is rigged like a spinnaker but the tack is fastened to the hull or to a bowsprit. It has greater camber than a genoa (but significantly less camber than a spinnaker). This is optimal for generating lift at larger angles of attack. An early form of gennaker was the "gollywhomper", used briefly in the 1870s. The gennaker is a specialty sail primarily used on racing boats to bridge the performance gap between a genoa and a spinnaker. It is sometimes the only downwind sail on board because it is easier to use and less expensive than a spinnaker. Due to its geometry, the sail is less prone to collapsing than a spinnaker. A gennaker is optimal for a beam reach, while an asymmetrical spinnaker is optimal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asymmetrical Spinnaker
An asymmetrical spinnaker is a sail used when sailing downwind. Also known as an "asym", "aspin", or "A-sail" it can be described as a cross between a genoa jib and a spinnaker. It is asymmetric like a genoa, but, the asymmetrical spinnaker is not attached to the forestay over the full length of its luff, being rigged like a spinnaker. The asymmetrical spinnaker has a larger camber than a genoa, making it optimal for generating lift at larger angles of attack, but the camber is significantly less than that of a spinnaker. The asymmetrical spinnaker is a specialty sail used on racing boats, bridging the performance gap between a genoa, which develops maximum driving force when the apparent wind angle is between 35 and 60 degrees, and a spinnaker, which has maximum power when the apparent wind is between 100 and 140 degrees. Due to its geometry, the sail is less prone to collapsing than a spinnaker and does not require the use of spinnaker pole. The sail can benefit greatly and be ...
