International Offshore Rule
The International Offshore Rule (IOR) was a measurement rule for racing sailboats. The IOR evolved from the Cruising Club of America (CCA) rule for racer/cruisers and the Royal Ocean Racing Club (RORC) rule. Rule context - past and present rating systems The IOR was superseded (in the early 1990s) by the International Measurement System (IMS) and CHS (since renamed IRC). While some IOR yachts race at club level under IRC in more or less their original form, others had major surgery to make them competitive within the new rules. Rule components The IOR concentrated on hull shape with length, beam, freeboard and girth measurements, foretriangle, mast and boom measurements, and stability with an inclination test. Additionally, the IOR identified features which were dangerous, or it couldn't fairly rate, and penalized or prohibited them. The measurements and penalties were used to compute the handicap number, called an ''IOR rating'', in feet. The higher the rating, the faster th ...

Cruising Club Of America
The Cruising Club of America (CCA) is an international organization of cruisers whose objects are to promote cruising and racing by amateurs, to encourage the development of suitable types of cruising craft, to stimulate interest in seamanship, navigation and handling small vessels, and to keep on file all information which may be of assistance to members in cruising in any waters. About The CCA was launched in the winter of 1922 at Maskells Harbour on Nova Scotia's Bras d'Or Lake by a handful of experienced offshore cruisers interested in cruising The founders included Gilbert Hovey Grosvenor, F.W. (Casey) Baldwin, William Washburn Nutting, Jim Dorsett, and William A. Wise Wood. As of 2021, the club has more than 1,400 members, including 116 women. Members range from 25 to 99 years of age, averaging 70.7 years. CCA members report owning 1,036 boats, averaging 41.3 feet. This includes 702 sailing yachts, 225 powerboats, and 49 "undesignated" boats." CCA's members personify the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1998 Sydney To Hobart Yacht Race
The 1998 Sydney to Hobart Yacht Race was the 54th annual running of the "blue water classic" Sydney to Hobart Yacht Race. It was hosted by the Cruising Yacht Club of Australia based in Sydney, New South Wales. It was the most disastrous in the race's history, with the loss of six lives and five yachts in an unexpectedly severe storm on 27–28 December. Fifty-five sailors were rescued in the largest peacetime search and rescue effort ever seen in Australia. Background The Sydney to Hobart Yacht Race is an annual event hosted by the Cruising Yacht Club of Australia, starting in Sydney, New South Wales on Boxing Day then heading south through the Tasman Sea, past Bass Strait, into Storm Bay and up the Derwent River, to cross the finish line in Hobart, Tasmania. The race distance is approximately . The race is run in co-operation with the Royal Yacht Club of Tasmania, and is widely considered to be one of the most difficult yacht races in the world. 1998 race The 1998 r ...

Offshore Racing Congress
The Offshore Racing Congress (ORC) is an international body for the sport of competitive sailing and is responsible for the establishment and maintenance of rating and classification standards used to define offshore, that is marine as opposed to inland, yacht racing handicap categories. Ratings and Classification The ORC was established in 1969 to create a single international handicap standard to combine the two pre-existing dominant handicap standards - that of the Cruising Club of America which covered North and South Americas, and the standard of the Royal Ocean Racing Club for Europe and the Antipodes. The combined ruleset, the International Offshore Rule or IOR, was initially successful. The ORC developed International Measurement System (IMS) in the early 1990s and it was widely used to the early 2000s. This made use of a Velocity prediction program or VPP. While still maintained, the IMS has been largely superseded by the Offshore Racing Congress Rule in its Intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxi Yacht
A maxi yacht usually refers to a racing yacht of at least in length. Origin The term ''maxi'' originated with the International Offshore Rule (IOR) rating system, which in the 1970s and 1980s measured offshore racing yachts and applied a single-number rating to each boat. This number was approximately equal to the sailing waterline length in feet, plus or minus speed enhancing or reducing factors in the design. A yacht with a rating of was generally about in length overall. The IOR had upper and lower rating limits of and , so a yacht designed and built to exceed the maximum limit of rating was known as a ''maxi''. Competition The IOR Maxis were generally long overall, and raced boat-for-boat without handicap, unlike the rest of the IOR fleet which raced with a time correction factor depending on the boat's rating. In the 1980s they were the most glamorous, exciting, expensive and high-visibility racing yachts in the world, with regular appearances at most of the great rac ...

ULDB
An Ultra Light Displacement Boat (or ULDB) is a term used to refer to a modern form of sailboat watercraft with limited displacement relative to the hull size (waterline length). Principally manufactured from the mid 1970s through mid 1980s, these boats generally sit higher in the water allowing them to move faster in nearly all water types other than directly crashing into larger waves, upwind, where the momentum of the water slows the boat down due to their lighter weights. They are typically racer-cruiser and/or "trailer sailer" boats that are excellent for towing, due to their light weight. They typically have cabins, but are designed for racing, excellent low-wind characteristics, large sail plans, and to have decent weight of crew-members to control heeling of the boat under medium winds, and higher. While some have keel-stepped masts and are raced in oceans, ocean bays, or offshore, such as the Olson 30, most have deck-stepped masts and are typically more common inland and ...

1/2 Ton
Half Ton class was an offshore sailing class of the International Offshore Rule racing the Half Ton Cup between 1967 and 1993. History In order that yachts of different types can race against each other, there are handicap rules which are applied to differect boat designs. The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..." When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fra ...

Scantlings
Scantling is a measurement of prescribed size, dimensions, or cross sectional areas. When used in regard to timber, the scantling is (also "the scantlings are") the thickness and breadth, the sectional dimensions; in the case of stone it refers to the dimensions of thickness, breadth and length. The word is a variation of '' scantillon'', a carpenter's or stonemason's measuring tool, also used of the measurements taken by it, and of a piece of timber of small size cut as a sample. Sometimes synonymous with story pole. The Old French ''escantillon'', mod. ', is usually taken to be related to Italian language">Italian ''scandaglio'', sounding-line (Latin ''scandere'', to climb; cf. ''scansio'', the metrical scansion). It was probably influenced by cantel, cantle, a small piece, a corner piece. Shipbuilding In shipbuilding, the scantling refers to the collective dimensions of the framing (apart from the keel) to which planks or plates are attached to form the hull. The word is m ...
