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 Rule context - past and present rating systems The IOR was superseded (in the early 1990s) by the International Measurement System (IMS) and CHS (since renamed IRC).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 the b ...

UFO 34 is a cruising and racing fibreglass monohull sailboat class. It is a sloop based on a design by Holman and Pye. The design features a spade rudder and a Bermuda rig with a large, overlapping headsail. Over 150 UFO 34s have been built both in the United Kingdom and Australia. The UFO 34 is a seaworthy yacht for offshore voyages, including extreme weather conditions, which also performs well in yacht racing. UFO 34 yachts competed both in the disastrous 1979 Fastnet and 1998 Sydney to Hobart yacht races, where lives and yachts were lost in the extreme conditions. UFO 34s performed effectively in both races, winning class IV in the Fastnet race and retiring without incident in the Sydney to Hobart. Production history ''Unidentified Flying Object'' won the Royal Yacht Squadron's de Maas Cup at Cowes in 1974 and many other races.

Half Ton Class
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 fracti ...
