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). -
Terminology of Yacht Parts, Fittings, Sails & Sheets Etc
Terminology of yacht parts, fittings, sails & sheets etc. Some of the obvious, and not so obvious, parts encountered on model yachts (and full size yachts). Bowsie, flat. Small drilled ‘plate’ through which runs a line, or cord, for adjustment of that line. Pre-war bowsies were often made in ivory, some were made in a fine plywood; today hard plastic is used. Bowsie, ring . A circular version of the flat bowsie, usually for larger yachts such as the A-class. Deck eye. An eye on a horizontal plate with fixing holes, located on the deck. Normally used for accepting backstay/forestay attachment, also shroud attachment on smaller yachts. Eyebolt. An eye, at the end of a threaded spigot, or bolt. Eyelet, sail. A sail eyelet is a brass part, in the shape of a ‘funnel’ before compression, and when pressed into a hole in a sail it makes a firm metal ring. It is then used to facilitate making off a line (or on occasions a wire hawser in full size practise). Larger/stronger eyelets used on laying up covers for full size boats, were turnovers , where a brass ring was firstly sewn in place over a hole punched in the sail or sheet, the turnover (eyelet) was then hammered in place using a rawhide mallet and dies. It made an immensely strong eyelet. Ferrule (slang, crimp). A brass ferrule, or sleeve, which when made off on one end of a wire, secures/attaches it by means of a loop made in the wire to a fitting or line. Head crane. -
Sailing Course Materials Overview
SAILING COURSE MATERIALS OVERVIEW INTRODUCTION The NCSC has an unusual ownership arrangement -- almost unique in the USA. You sail a boat jointly owned by all members of the club. The club thus has an interest in how you sail. We don't want you to crack up our boats. The club is also concerned about your safety. We have a good reputation as competent, safe sailors. We don't want you to spoil that record. Before we started this training course we had many incidents. Some examples: Ran aground in New Jersey. Stuck in the mud. Another grounding; broke the tiller. Two boats collided under the bridge. One demasted. Boats often stalled in foul current, and had to be towed in. Since we started the course the number of incidents has been significantly reduced. SAILING COURSE ARRANGEMENT This is only an elementary course in sailing. There is much to learn. We give you enough so that you can sail safely near New Castle. Sailing instruction is also provided during the sailing season on Saturdays and Sundays without appointment and in the week by appointment. This instruction is done by skippers who have agreed to be available at these times to instruct any unkeyed member who desires instruction. CHECK-OUT PROCEDURE When you "check-out" we give you a key to the sail house, and you are then free to sail at any time. No reservation is needed. But you must know how to sail before you get that key. We start with a written examination, open book, that you take at home. -
From the Editor
From the Editor The Spritsail The spritsail is a small boat rig of respectable antiq uity used around the world. Its name comes from the sprit, a spar comparable to a gaff, but attached much lower on the mast. The sprit crosses diago nally to the uppermost comer of the sail, which it extends and elevates. The Woods Hole Spritsail Boat was originally used for fishing and later became popular among local and summer residents for racing and sailing. Slim mer, deeper, and with more freeboard than a catboat, it was fairly easy to row and was a good boat in the fierce tides of Woods Hole. The spritsail rig was certainly influenced by the stone bridge built across Eel Pond Channel in 1878-1879. The mast of the spritsail was stepped far forward and held at the bow by a pinned bracket. When approaching the fixed bridge, the boatman removed the pin, and mast and sail dropped into the boat, allowing the spritsail to enter Eel Pond. As we launch this new Spritsail, A Journal of Fal mouth History, we hope it will prove to be as useful and "handy to have around II as the old spritsail boat. We want it to be jaunty and trim, good fOI all weather, fun to usc, and valuable to year-round and summer residents alike. To this community of Fal mouth, with its splendid maritime past, we offer this Spritsail for pleasure, adventure and exploration of the currents of local history. Mary Lou Smith . -

Pocket-Luff Rigs the Pocket Luff Rig Was First Used on Moths in Australia in the 1960S
Pocket-Luff Rigs The pocket luff rig was first used on Moths in Australia in the 1960s. It was then re-introduced by Ian Ward in 1993 and used by him in the 1993 Worlds in England. It showed moments of great boat speed which prompted Emmett Lazich to change over to a pocket luff rig in his return from these Worlds. Development was initially slow until more sailors switched to using them. Then, in the final few months before the Worlds in Australia in late 1994, there was some extremely rapid development, leading to the rigs we are using now. I have been continually refining my rig, and the rig I used in the most recent Nationals in Melbourne is the result. I think it is arguably the best all- round rig available.I will now try to explain why I think pocket luff rigs are faster than standard bolt rope sails. This is only my opinion, and since I am not an expert on sails, my explanations may be different from what might be in the text books. But here goes anyway ! I think the main reason why pocket luff sails are faster is that the wind is attached to the leeward side of the sail straight away, which enables them to generate more power at a lower wind strength than the bolt rope sail. In contrast, the bolt rope sail has much greater turbulence in the area immediately behind the mast. The smooth entrance in the pocket luff sail is achieved through the use of camber inducers which are connected to the battens. -
Pacific Colonisation and Canoe Performance: Experiments in the Science of Sailing
PACIFIC COLONISATION AND CANOE PERFORMANCE: EXPERIMENTS IN THE SCIENCE OF SAILING GEOFFREY IRWIN University of Auckland RICHARD G.J. FLAY University of Auckland The voyaging canoe was the primary artefact of Oceanic colonisation, but scarcity of direct evidence has led to uncertainty and debate about canoe sailing performance. In this paper we employ methods of aerodynamic and hydrodynamic analysis of sailing routinely used in naval architecture and yacht design, but rarely applied to questions of prehistory—so far. We discuss the history of Pacific sails and compare the performance of three different kinds of canoe hull representing simple and more developed forms, and we consider the implications for colonisation and later inter-island contact in Remote Oceania. Recent reviews of Lapita chronology suggest the initial settlement of Remote Oceania was not much before 1000 BC (Sheppard et al. 2015), and Tonga was reached not much more than a century later (Burley et al. 2012). After the long pause in West Polynesia the vast area of East Polynesia was settled between AD 900 and AD 1300 (Allen 2014, Dye 2015, Jacomb et al. 2014, Wilmshurst et al. 2011). Clearly canoes were able to transport founder populations to widely-scattered islands. In the case of New Zealand, modern Mäori trace their origins to several named canoes, genetic evidence indicates the founding population was substantial (Penney et al. 2002), and ancient DNA shows diversity of ancestral Mäori origins (Knapp et al. 2012). Debates about Pacific voyaging are perennial. Fifty years ago Andrew Sharp (1957, 1963) was sceptical about the ability of traditional navigators to find their way at sea and, more especially, to find their way back over long distances with sailing directions for others to follow. -
Boats Spritsail Collection
Woods Hole Historical Museum Archives P.O. Box 185 Woods Hole, MA 02543 REGISTER Boats: Spritsail Collection 1896 -2017 2 boxes 2 BOATS Woods Hole Spritsail Collection History The use of the spritsail boat in Woods Hole is believed to have originated in the 1870s. The local fishermen found the spritsail boat more suitable for their work than the popular catboat. The areas where they wanted to fish were subject to the six foot tidal current of the channel and the strong southwest prevailing wind coming down Vineyard Sound. The spritsail was a strong boat with excellent sea keeping qualities and handled well especially when the current opposed the wind with the resulting Woods Hole rip tide. Local fishermen worked alone and the spritsail, unlike the catboat, was narrow enough to be rowed by one. Woods Hole boats also needed a mast which could be unstepped in a hurry. Most of the boats were moored in Eel Pond and had to pass under a fixed stone bridge too low to admit sailboats with their mast stepped. The loose footed spritsail rig helped speed the operation and allowed quick access to the pond. At first the spritsails were used only for fishing, lobstering, and transportation. These working boats were only occasionally raced until the summer residents became interested in them. They soon wanted their own spritsails to sail and race. However they did not want the strong sturdy boats of the fishermen. While maintaining the same general pattern of the fishing spritsail, the spritsails built for the summer people had a lighter and faster hull and lacked the very high freeboard and coaming of the fishing spritsails. -
