  • The Junk Rig Glossary (JRG) Version 20 APR 2016
    The Junk Rig Glossary (JRG) Version 20 APR 2016 Welcome to the Junk Rig Glossary! The Junk Rig Glossary (JRG) is a Member Project of the Junk Rig Association, initiated by Bruce Weller who, as a then new member, found that he needed a junk 'dictionary’. The aim is to create a comprehensive and fully inclusive glossary of all terms pertaining to junk rig, its implementation and characteristics. It is intended to benefit all who are interested in junk rig, its history and on-going development. A goal of the JRG Project is to encourage a standard vocabulary to assist clarity of expression and understanding. Thus, where competing terms are in common use, one has generally been selected as standard (please see Glossary Conventions: Standard Versus Non-Standard Terms, below) This is in no way intended to impugn non-standard terms or those who favour them. Standard usage is voluntary, and such designations are wide open to review and change. Where possible, terminology established by Hasler and McLeod in Practical Junk Rig has been preferred. Where innovators have developed a planform and associated rigging, their terminology for innovative features is preferred. Otherwise, standards are educed, insofar as possible, from common usage in other publications and online discussion. Your participation in JRG content is warmly welcomed. Comments, suggestions and/or corrections may be submitted to [email protected], or via related fora. Thank you for using this resource!

  • Armed Sloop Welcome Crew Training Manual
    HMAS WELCOME ARMED SLOOP WELCOME CREW TRAINING MANUAL Discovery Center ~ Great Lakes 13268 S. West Bayshore Drive Traverse City, Michigan 49684 231-946-2647 [email protected] (c) Maritime Heritage Alliance 2011 1 1770's WELCOME History of the 1770's British Armed Sloop, WELCOME About mid 1700’s John Askin came over from Ireland to fight for the British in the American Colonies during the French and Indian War (in Europe known as the Seven Years War). When the war ended he had an opportunity to go back to Ireland, but stayed here and set up his own business. He and a partner formed a trading company that eventually went bankrupt and Askin spent over 10 years paying off his debt. He then formed a new company called the Southwest Fur Trading Company; his territory was from Montreal on the east to Minnesota on the west including all of the Northern Great Lakes. He had three boats built: Welcome, Felicity and Archange. Welcome is believed to be the first vessel he had constructed for his fur trade. Felicity and Archange were named after his daughter and wife. The origin of Welcome’s name is not known. He had two wives, a European wife in Detroit and an Indian wife up in the Straits. His wife in Detroit knew about the Indian wife and had accepted this and in turn she also made sure that all the children of his Indian wife received schooling. Felicity married a man by the name of Brush (Brush Street in Detroit is named after him).

  • Mast Furling Installation Guide
    NORTH SAILS MAST FURLING INSTALLATION GUIDE Congratulations on purchasing your new North Mast Furling Mainsail. This guide is intended to help better understand the key construction elements, usage and installation of your sail. If you have any questions after reading this document and before installing your sail, please contact your North Sails representative. It is best to have two people installing the sail which can be accomplished in less than one hour. Your boat needs facing directly into the wind and ideally the wind speed should be less than 8 knots. Step 1 Unpack your Sail Begin by removing your North Sails Purchasers Pack including your Quality Control and Warranty information. Reserve for future reference. Locate and identify the battens (if any) and reserve for installation later. Step 2 Attach the Mainsail Tack Begin by unrolling your mainsail on the side deck from luff to leech. Lift the mainsail tack area and attach to your tack fitting. Your new Mast Furling mainsail incorporates a North Sails exclusive Rope Tack. This feature is designed to provide a soft and easily furled corner attachment. The sail has less patching the normal corner, but has the Spectra/Dyneema rope splayed and sewn into the sail to proved strength. Please ensure the tack rope is connected to a smooth hook or shackle to ensure durability and that no chafing occurs. NOTE: If your mainsail has a Crab Claw Cutaway and two webbing attachment points – Please read the Stowaway Mast Furling Mainsail installation guide. Step 2 www.northsails.com Step 3 Attach the Mainsail Clew Lift the mainsail clew to the end of the boom and run the outhaul line through the clew block.

  • & Marine Engineering
    REFERENCE ROOM Naval Architecture & Marine Engineering ft* University of Michigan Ann Arbgr, M g109 THE UNIVERSITY OF MICHIGAN COLLEGE OF ENGINEERING Department of Naval Architecture and Marine Engineering DESIGN CONSIDERATIONS AND THE RESISTANCE OF LARGE, TOWED, SEAGOING BARGES J. L. Moss Corning Townsend III Submitted to the SOCIETY OF NAVAL ARCHITECTS AND MARINE ENGINEERS Under p. O. No. 360 September 15, 1967 In the last decade, -ocean-going unmanned barges have become an increasingly important segment of our merchant marine. These vessels, commonly over 400 feet long, and sometimes lifting in excess of 15,000 L.T. dead weight, are usually towed on a long hawser behind a tugboat. Because the barges are inherently directionally unstable, twin out- board skegs are attached to achieve good tracking. Model tests are conducted in order to determine towline resistance and the proper skeg position which renders the barge stable. Skegs, vertical appendages similar to rudders, are placed port and starboard on the rake. They create lift and drag, and move the center of lateral pressure aft, thus tending to stabilize a barge towed on a long line. At The University of Michigan many such model experiments have been conducted within the past several years. Since these tests have been carried out for various industrial con- cerns and on specific designs, systematic variations of parameters or other means of specifically relating the results have not been possible in most cases. Nevertheless, on the basis of the results of these largely unrelated tests, recom- mendations can be made regarding good design practice and some specific aspects can be demonstrated.

  • The Poor Man's Ljungström
    The poor man’s Ljungström rig (.. or how a simplified Ljungström rig can be a good alternative on a small boat...) ..by Arne Kverneland... ver. 20110722 Fredrik Ljungström: Once upon a time there lived an extraordinary man in Sweden, named Fredrik Ljungström (1875 – 1964). Like his father and brothers he turned out to be an inventor, even greater than the others. Among his over 200patents (some shared with others) the most lucrative were probably efficient steam turbines to drive electric generators and locomotives (1920) and even more important, the rotating heat regenerator which cut the coal consumption on the steam engines with over 30% (around 1930). Going through the list of patents, it is clear that he must have been a real multi-genius (.. for more info, just google Fredrik Ljungström...). The Ljungström rig – the original: Being also a keen sailor, in 1935 Mr. Ljungström came up with another brilliant idea; the Ljungström rig (Lj-rig). He had learned how dangerous it could be to handle sail on the foredeck of a small boat and his solution was radical: The diagram above of a Ljungström rig is copied from the book “RACING, CRUISING and DESIGN by Uffa Fox. (ISBN 0-907069-15-0 in UK, 0-87742-213-3 in USA). Great reading! This is a one-sail rig set on a freestanding wooden mast (.. in later designs the aft stay was omitted). The luff boltrope of the doubled sail went in a track in the mast and just as today’s roller genoas it was hoisted in spring and lowered at the end of the season.

  • Rapier 550 - Standard Specification
    Page 1 of 11 Rapier 550 - Standard Specification Construction The structure of the Rapier 550 is of a modern lightweight construction using the using the latest resin infusion processes and combines high strength Epoxy resin systems throughout the entire structure with a combination of E glass, Kevlar and carbon laminate stiffened by PVC cores to produce an exceptionally strong and light structure optimised for performance sailing. The hull has an exterior gel coat finish with vinylester skin and choice of colours. Everything is female moulded in hi-quality production tooling. The deck and superstructure has an integrally moulded anti-slip surface in places where needed – especially in all areas where crew or guests walk or require access to operate the vessel. The Broadblue Rapier 550 is virtually unsinkable due to its watertight bulkheads, cored construction and buoyancy compartments fore and aft in each hull. Each compartment is separate and sealed off to control water ingress if damaged. All internal textures are a combination of painted, light weight linings, timber and textile trims. The skeg keels of the R550 are separately moulded and bonded to the hull structure, maintaining the integrity of the hull even if the keels are damaged or detached. Other keel options are also available, including low aspect ratio fixed keels, dagger boards and steerable canards. Outside Deck areas Side decks are moulded with non-slip integral to the construction (aft sections can have optional teak/teak-alike surface). All windows to saloon and coach-roof are constructed from appropriate thickness toughened glass.
