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).

  • USS CONSTELLATION Page 4 United States Department of the Interior, National Park Service National Register of Historic Places Registration Form
    NPS Form 10-900 USDI/NPS NRHP Registration Form (Rev. 8-86) OMB No. 1024-0018 USS CONSTELLATION Page 4 United States Department of the Interior, National Park Service National Register of Historic Places Registration Form Summary The USS Constellation’s career in naval service spanned one hundred years: from commissioning on July 28, 1855 at Norfolk Navy Yard, Virginia to final decommissioning on February 4, 1955 at Boston, Massachusetts. (She was moved to Baltimore, Maryland in the summer of 1955.) During that century this sailing sloop-of-war, sometimes termed a “corvette,” was nationally significant for its ante-bellum service, particularly for its role in the effort to end the foreign slave trade. It is also nationally significant as a major resource in the mid-19th century United States Navy representing a technological turning point in the history of U.S. naval architecture. In addition, the USS Constellation is significant for its Civil War activities, its late 19th century missions, and for its unique contribution to international relations both at the close of the 19th century and during World War II. At one time it was believed that Constellation was a 1797 ship contemporary to the frigate Constitution moored in Boston. This led to a long-standing controversy over the actual identity of the Constellation. Maritime scholars long ago reached consensus that the vessel currently moored in Baltimore is the 1850s U.S. navy sloop-of-war, not the earlier 1797 frigate. Describe Present and Historic Physical Appearance. The USS Constellation, now preserved at Baltimore, Maryland, was built at the navy yard at Norfolk, Virginia.

    maelstrom web browser free download 11 Interesting Web Browsers (That Aren’t Chrome) Whether it’s to peruse GitHub, send the odd tweetstorm or catch-up on the latest Netflix hit — Chrome’s the one . But when was the last time you actually considered any alternative? It’s close to three decades since the first browser arrived; chances are it’s been several years since you even looked beyond Chrome. There’s never been more choice and variety in what you use to build sites and surf the web (the 90s are back, right?) . So, here’s a run-down of 11 browsers that may be worth a look, for a variety of reasons . Brave: Stopping the trackers. Brave is an open-source browser, co-founded by Brendan Eich of Mozilla and JavaScript fame. It’s hoping it can ‘save the web’ . Available for a variety of desktop and mobile operating systems, Brave touts itself as a ‘faster and safer’ web browser. It achieves this, somewhat controversially, by automatically blocking ads and trackers. “Brave is the only approach to the Web that puts users first in ownership and control of their browsing data by blocking trackers by default, with no exceptions.” — Brendan Eich. Brave’s goal is to provide an alternative to the current system publishers employ of providing free content to users supported by advertising revenue.

  • SHALLOW BOATS; DEEP ADVENTURES! Since 1984
    Since 1984 SHALLOW BOATS; DEEP ADVENTURES! 1 SHOAL DRAFT STABILITY, SIMPLICITY, SPEED AND SAFETY. I’m here to talk about a belief in and a passion for shoal-draft boats, particularly the development of the Round Bottomed Sharpie. I started sailing in centreboard dinghies and that excitement has returned with these boats. As you’ll see these 2 boats have become known as Presto Boats. NEW HAVEN OYSTER- TONGING SHARPIE By definition a Sharpie is a flat-bottomed boat and a New Haven oyster-tonging sharpie looked like this. They were easy to build with their box shape & simple rigs but the boat is an ingenious piece of function and efficiency. The stern is round so the tongs don’t snag on transom corners; the freeboard is low so it’s easy to swing the tongs on board and the long centreboard trunk stops the oysters from shifting SEA OF ABACO 3 under sail. NEW HAVEN SHARPIE RIG The unstayed masts rotate through 360 degrees so the oystermen would sail to windward of the oyster beds and let the sails stream out over the bow while drifting over the beds tonging away. The sails are self-tending and self-vanged so handling is very easy. The boats are fast when loaded so you can get the oysters fresh to market. Oyster bars in big cities were the Starbucks of the late 1800s. You’d pop in for a ½ dozen as a pick-me-up. 4 On the right is an Outward Bound 30 to our design. With our contemporary Sharpies we’ve retained the principles of the traditional rig; it works as well today as it did in the 1800s.

CCAS ceased to exist as an organization in 1979, but the BCAS board decided in 1993 that the CCAS Statement of Purpose should be published in our journal at least once a year. We first came together in opposition to the brutal aggression of the United States in Vietnam and to the complicity or silence of our profession with regard to that policy. Those in the field of Asian studies bear responsibility for the consequences of their research and the political posture of their profession. We are concerned about the present unwillingness of specialists to speak out against the implications of an Asian policy committed to en- suring American domination of much of Asia.

  • Readin' Both Pages
    Readin’ Both Pages A membership publication of the Sail, Power & Steam Museum Vol. 1, No. 1 Winter 2008 Rekord ~ A Fascinating Freighter From the Memoirs of Capt. Jim Sharp Life is too short to own an ugly boat! That was my motto and I adhered to it with almost religious devotion. The next boat I was destined to drag into Camden Harbor was one interesting and handsome vessel. Although sailing was still very much my forte, this little ship conveyed the closest thing to worship of a power vessel that this old codger can conjure up. She was called the Record, spelled Rekord in old Norwegian, and was more than attractive in a thousand different ways. Rekord had history, intrigue, humor, challenge, personality and humility, all trunnelled together into one magnificent hull. Museum volunteers and staff were busy throughout the summer season working on many projects aboard Rekord. In this picture, Ben Breda applies fresh white paint to the starboard foredeck rail. Her ad was buried deep among the many listings in the “Yellow Pages” (that’s the scandal sheet of boats for sale shoe ... it was not bad. There was some worming, but noth- in the commercial world). I should never have taken my ing that would be a structural problem. And those worms copy into Fitzpatrick’s Deli to peruse the Boats For Sale would soon die in our cold Maine water. I think I knew I listings over my coffee. It was just a small picture and would buy this boat before even stepping aboard. Then I really fuzzy, but it snapped the hair-trigger on my snooping asked the owner about the engine.
