Dandy Rig
A yawl is a type of boat. The term has several meanings. It can apply to the rig (or sailplan), to the hull type or to the use which the vessel is put. As a rig, a yawl is a two masted, fore and aft rigged sailing vessel with the mizzen mast positioned abaft (behind) the rudder stock, or in some instances, very close to the rudder stock. This is different from a ketch, where the mizzen mast is forward of the rudder stock. The sail area of the mizzen on a yawl is consequentially proportionately smaller than the same sail on a ketch. As a hull type, yawl may refer to many types of open, clinker-built, double-ended, traditional working craft that operated from the beaches of Britain and Ireland. These boats are considered to be linked to the Viking or Nordic design tradition. Most of these types are now extinct, but they include the Norfolk and Sussex Beach Yawls (called "yols" by the men who crewed them), which were probably the fastest-sailing open boats ever built.

Chubasco Photo D Ramey Logan
A chubasco is a violent squall with thunder and lightning, encountered during the rainy season along the Pacific coast of Mexico, Central America, and South America. The word chubasco has its origins in the Portuguese word '' chuva'' which means rain. The monsoon storms that regularly pass over the southwestern United States, including the southern regions of Arizona and New Mexico, are sometimes referred to as chubascos.''Mohave Daily Miner'', Sep 2, 1984.https://news.google.com/newspapers?nid=943&dat=19840902&id=EIALAAAAIBAJ&sjid=S1MDAAAAIBAJ&pg=3278,11733 In the northern parts of Mexico, especially the northeast and north central, the word chubasco is used especially for suddenly occurring localised storms that produce very strong winds, sometimes as much as 90 miles per hour, and intense rains of as much as 5-6 inches in less than an hour. Straight-line winds In meteorology, a downburst is a strong downward and outward gushing wind system that emanates from a point sourc ...

Self-steering Gear
Self-steering gear is equipment used on sail boats to maintain a chosen course or point of sail without constant human action. History Mechanical or "wind vane" self-steering started out as a way to keep model sail boats on course. Before the advent of radio control, model yacht racing (started before WW1) was typically contested on long narrow ponds, and the number of stops along the banks was counted as a penalty in the final result. Initially a system of counterweight on the tillers was devised to compensate for the weather helm when the model boat heeled in a gust. These crude systems evolved in a more sophisticated system called Braine Gear after its inventor, George Braine. The Braine steering gear was a fine-tuned system of quadrant on the rudder stock driven by the tension of the mainsail sheet and damped by a rubber band. A more sophisticated system called the vane gear was later devised, it relied on a small vane or airfoil driving the main rudder via an adjustable ...

Longline Fishing
Longline fishing, or longlining, is a commercial fishing angling technique that uses a long ''main line'' with baited hooks attached at intervals via short branch lines called ''snoods'' or ''gangions''.Method and Apparatus for Long Line and Recreational Bait Fishing Patent application 20080202013. 28 August 2008. A snood is attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the . This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. This can l ...

Pollachius Virens
The saithe ( or ) (''Pollachius virens'') is a species of marine fish in the Pollock genus ''Pollachius''. Together with '' P. pollachius'', it is generally referred to in the United States as pollock. Other names include the Boston blue (separate from bluefish), coalfish/coley, and saithe in the UK, where the young fish are called podleys in Scotland and northern England. Description This species can be separated from ''P. pollachius'' by looking at the relative lengths of the upper and lower jaws. ''P. pollachius'' has a longer underslung lower jaw while ''P. virens'' has approximately equal upper and lower jaw lengths. This gives a very different profile to the head. In general, ''P. pollachius'' is a brown or golden colour with a dark back while ''P. virens'' is bright silver with a very dark green back. ''P. virens'' generally appears to have relatively smaller eyes. The lateral line of ''P. pollachius'' has a noticeable kink over the pectoral fins while that of ''P. viren ...

Yoal
The yoal, often referred to as the ness yoal, is a clinker (boat building), clinker-built craft used traditionally in Shetland, Scotland. It is designed primarily for rowing, but also handles well under its traditional square sail when running before the wind or on a broad reach. The word is cognate with Yawl#Scotland: yawl/yole/yoal, yawl and yole. Construction Until about 1860, yoals were imported in kit form from the area around Bergen in Norway. The traditional small wooden boats were known as either Strandebarmer or Oselvar from Os, Hordaland, Os in Hordaland, Norway. The wooden boats were taken apart and then 'flat packed' for shipping to the Shetland Islands. Instead of sending complicated assembly instructions, they sent Norwegian boatbuilders to re-build them. However, increasing customs duty meant that Shetland builders took over the building but stayed mostly with the original Norwegian design. All the parts of a yoal have a name, perhaps to make assembly easier when ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cognate
In historical linguistics, cognates or lexical cognates are sets of words in different languages that have been inherited in direct descent from an etymology, etymological ancestor in a proto-language, common parent language. Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and often it takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate or not. Cognates are distinguished from Loanword, loanwords, where a word has been borrowed from another language. The term ''cognate'' derives from the Latin noun '':wikt:cognatus, cognatus blood relative'. Characteristics Cognates need not have the same meaning, which semantic drift, may have changed as the languages developed independently. For example English language, English ''wikt:starve#English, starve'' and Dutch language, Dutch ''wikt:sterven#Dutch, sterven'' 'to die' or German languag ...

Bermuda Sloop
The Bermuda sloop is a historical type of fore-and-aft rigged single-masted sailing vessel developed on the islands of Bermuda in the 17th century. Such vessels originally had gaff rigs with quadrilateral sails, but evolved to use the Bermuda rig with triangular sails. Although the Bermuda sloop is often described as a development of the narrower-beamed Jamaica sloop, which dates from the 1670s, the high, raked masts and triangular sails of the Bermuda rig are rooted in a tradition of Bermudian boat design dating from the earliest decades of the 17th century. It is distinguished from other vessels with the triangular Bermuda rig, which may have multiple masts or may not have evolved in hull form from the traditional designs. History Jamaica was the locus of building fast single-masted vessels that became the model for small cruisers of the Royal Navy. Building of this type of vessel had become more active in Bermuda by the start of 18th century. Bermuda shipbuilders constructed ...

Center Of Pressure (fluid Mechanics)
In fluid mechanics, the center of pressure is the point where the total sum of a pressure field acts on a body, causing a force to act through that point. The total force vector acting at the center of pressure is the surface integral of the pressure vector field across the surface of the body. The resultant force and center of pressure location produce an equivalent force and moment on the body as the original pressure field. Pressure fields occur in both static and dynamic fluid mechanics. Specification of the center of pressure, the reference point from which the center of pressure is referenced, and the associated force vector allows the moment generated about any point to be computed by a translation from the reference point to the desired new point. It is common for the center of pressure to be located on the body, but in fluid flows it is possible for the pressure field to exert a moment on the body of such magnitude that the center of pressure is located outside the ...

Drascombe Lugger
The Drascombe Lugger is a British trailerable sailboat that was designed by John L. Watkinson and first built in 1968. The Drascombe Lugger design is the basis of a large range of similar Drascombe boats with different hull, cabin and rig configurations. Production The design is built by Honnor Marine Classics and also by Churchouse Boats, now called Drascombe Boats in the United Kingdom. Production started in 1968, with more than 2,000 boats completed and the design remains in production. Design The boat was designed by Watkinson, who was a former Royal Navy officer. In the early 1960s he wanted to build a small boat for his own family use. His design goals were for a day sailer with trailerability, that would be stable and safe, but still exciting to sail for experienced sailors. The prototype was built of wood on a farm in Drascombe Barton. The design was based upon the fishing boats used on England's northeastern coast, which trace their lineage back to the Vikin ...
