Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from just one landmark. The angular dip of an object (island or vessel) below the visible horizon can also be used to determine the distance to it. This booklet explains how to get the best results from plastic sextants, and presents numerical comparisons with similar data from metal sextants. Sextant piloting techniques are also reviewed as they are an ideal use of a plastic sextant.

A young schooner bum, thrilled by the ways of a windjammer, resolves to acquire his own boat and follow the sea in search of pals and gals and utopian freedom. It is the mid 1950s, he is in his early twenties, and while building his own boat he rather suddenly finds himself to be a family man. Undeterred, he and his bride, now five and a half months pregnant, sail out through the Golden Gate in an experimental contraption and turn left for Mexico. They don't know it at the time, and they wouldn't have cared, but their tiny boat is the first three-hulled watercraft to go to sea in modern times. Soon the author becomes an unintended "instant expert" in what would become, fifty years later, an absolute sea change in marine architecture. This work in two volumes tells of those fifty years, of the people, the boats, the foibles and the fables, the history and lore that - despite a sometimes fierce resistance from the Corinthian community - comprise the origins of today's modern catamarans, trimarans and proas. Told as the memoir of a septuagenarian sea dog whose failing eyesight causes him to "see" his memories, Jim Brown recounts the multihull milestones of the 1950s to the 70s (Volume One) and the 1970s into the new millennium (Volume Two). He highlights the pivotal multihull pioneers, and relates the controversial advent and eventual ascendance of multihulls today, with their implications for tomorrow. However, this rich nautical heritage runs as but a thread through the fabric of how the multihull phenomenon shapes the lives of the writer and his family and friends. His obsession is fulfilled in ways far different from his youthful promise to himself.
Round the World in the Wrong Season, by Eric T. Wiberg - Written between 1994 and 2009, is a memoir of global travel and an unfulfilled college crush. The book follows the narrator out of school and across the Pacific. At only 23 he has command of a 68-foot Burmese-teak ketch built in Scotland thrust upon him. The owner is on a voyage home to his death, and along the way they hire sailors twice the skipper's age. They makes it to New Zealand in a storm which sinks seven yachts, then spends months shearing sheep and writing a memoir. By the time the narrator makes a rendezvous with his college sweetheart (who has been teaching Thai students on the Burmese border), she seems to have all but forgotten him. This leads to a less than satisfactory denouement and puts at least one of them in the hospital. The book includes extensive photographs and hand-drawn charts and a detailed bibliography. It is over 400 pages in length, perfect bound in cloth. More www.wrongseason.net and www.ericwiberg.com

Celestial navigation is a way to find your latitude and longitude on earth using a sextant to measure the angular heights of celestial bodies above the horizon. It has been used by mariners at sea and explorers on land for three hundred years, and it is still used today as a dependable backup to modern electronic navigation. Routine celestial navigation relies upon accurate time (Universal Time) to find the longitude of a position (latitude does not require time). Advanced celestial navigators can find longitude without knowing the time using a technique called Lunar Distance. In this technique, the sextant is used to measure the angular (diagonal) distance between the moon and another celestial body. Since this distance slowly changes as the moon moves eastward though the stars, it can be used to find the time of day that is needed to complete the longitude determination.The process of finding longitude from lunar distance, however, requires special tables that have not been published in the Nautical Almanac or other sources since the early 1900s. Although software solutions have been available, most advanced celestial navigators are very grateful to navigation historian Bruce Stark for creating these printed tables dedicated to this task. They have been used and tested by mariners for more than 15 years and are praised by experts for their ingenuity and ease of use in solving this complex navigation exercise-which all agree is the hallmark of an expert celestial navigator.With The Stark Tables in your nav station, you no longer have to fear losing power to your electronic navigation aids, nor are you dependent on accurate time from any official broadcast.Besides their practical use in back up navigation, historians have used these tables for years to interpret the logbooks of Lewis and Clark, David Thompson, James Cook, Matthew Flinders, George Vancouver, Nathaniel Bowditch, and other notable explorers and sea captains."It is remarkable in this day when the very survival of celestial navigation seems in question, that an individual should suddenly appear on the scene and present to the world such a brilliant piece of work. Stark has rendered a great service to the celestial navigation community." - Robert Eno, The Navigator's Newsletter"Captain Cook would have relished using these tables, had they been available to him then."- George Huxtable, FRIN
This volume is a narrative of Scott's last expedition from its departure from England in 1910 to its return to New Zealand in 1913.

Small Trimarans. Here is another opportunity for you to sit down
with the experts and get your questions answered about the
fascinating small trimarans out there
The most authoritative manual available on today's cruising boats and their equipment, written by some of the world's most respected and experienced sailors and yacht designers.
This book is ground breaking not because of what it has, but what it doesn't have: No complicated drawings; no mathematics problems; no astronomical talk; no big words you've never heard of. Sailor-author Gene Grossman finally breaks this wonderful subject down into plain English and explains it in such a way that you will no longer have any excuse to claim that you know nothing about the valuable boater's subject of Celestial Navigation. This book was inspired by Gene's DVD program of the same title, which has gained worldwide popularity and is being used the the Navy, Coast Guard and sailing schools all over the world.
"Navigation puzzles, controversies, historical problems, and other ponderables demystified by an expert navigator and writer. Joe Portney is a US Naval Academy graduate and Air Force navigator who has participated in three historic flights over the North Pole. He is a past President of the Institute of Navigation and recipient of the Weems Award for continuing contributions to the art and science of navigation. He has produced a wonderful little book here, chock filled with interesting tidbits, each of which can be read in a few minutes but will stimulate your thought for many days to come. Some are very basic, others more involved, but he provides a clear explanation of each. Some refer to math computations that we might not all be familiar with, but this is not a distraction from the main points being made even in these few cases."
It was 1989 when I started building a large 1/4"= 1 foot scale model of Constitution and today, 16 years and 18,000 hours later, I honestly believe this is how she was rigged during her last chase, exactly one hour prior to her last battle against the British HMS Levant and HMS Cyane. I had already invested more than four thousand hours in the construction of this model, and had intended, upon completion of the hull, to proceed with the stepping of masts and rigging her just as I had done previously on other models. However, In February 1992, when Commander Martin presented me with an original typescript of Midshipman Edward Clifford Anderson's notes on the rigging of the ship in 1834-35 at Boston, the earliest such specific information known, I decided I would follow Midshipman Anderson's directions and record the progress, step by step, discovering for myself what was done and how. This meant creating additional scaled parts relating to sheer poles, etc. to simulate exactly how the masts and the bowsprit, etc. were stepped in this era, and for this reason. Due to the equipment available today, and rightfully so, I do not believe that Constitution, or any ship's from this era, will ever again be rigged, including the stepping of the masts, using sheer poles and tackle only, and so I chose, while this one and only opportunity lent itself, to show this pictorially.
This is the Information Sailors and Prospective Boat Builders Want to Know About Today's Production and Homebuilt Small Trimarans. Imagine being able to sit down with experts for many of the new, most popular, and frequently sought after production or homebuilt small trimarans in the world today. Well, now you can Are you ready for a behind-the-scenes look at some of your favorite small trimarans? This book includes the following information: 1) Newly published pictures and tips about these super fast,
ultra-fun sailboats There isn't a lot of "technical" information within these pages. Some information might fit into a technical section (if one were included), but there isnt any because that wasn't a goal. It should be fairly easy to go on the Internet and uncover the technical data for any of these boats if you really want it. The simple goal of this particular work was to have those who are most knowledgeable discuss the stories and insights behind the sailboats they personally know -- in some cases, better than anyone else in the world. The small trimarans featured in this book fall into 2 categories: Production Sailboats (which I also sometimes refer to as "commercial" or "commercially produced" boats) & Self-Built Sailboats. This is really the only "logical" arrangement of order. There is one exception -- the Trinado model. Featured boats include: The Magnum 18, 21 & 21S Trimarans ... The Windrider 16, 17 & Rave (Hydrofoil) Trimarans ... The Weta Beach Trimaran] The Wa'apa & Tamanu Small Trimaran Sailing Canoes ... The Fast 17, A18T, A21, Cardiff 21 & Z65 Small Trimarans ... The Seaclipper 10 & 16 Trimarans ] The Scarab Small Trimaran Models ... The Discovery 20 Small Trimaran... The Warren 23' & 27' Small Trimarans ... The L7, Multi 23 & Beach Tri 22 Small Trimarans ... The KH 16', Spitfire 20' & KH 23' Small Trimarans... The Trinado Trimaran... The Tremolino Trimaran... The K24T Small Cabin Cruiser Trimaran] Plus -- An Interview about Wooden Boatbuilding with Chuck Leinweber (publisher of Duckworks Magazine). Interviews featuring production models are in the front. And the small trimaran models most often "self-built" at home by a do-it-yourselfer follow. This order of arrangement isn't meant to convey some boats are "better" than others. Such assessment is purely subjective. Itll be shaped most often by what an individual wants in a boat at any given time. In my opinion, all of boats talked about in these pages are fun, fast and desirable.
When Daniel Robb set out to rebuild a family sailboat that had been deteriorating for years, he couldn't have anticipated what he was getting into. Although Robb was a skilled carpenter, boatbuilding (and boat repair) required a specialized set of skills. And this wasn't just any boat; it was a Herreshoff 12 1/2, a classic wooden sailboat. Built especially for the coastal waters of New England, this little sloop had sailed for years out of the author's boyhood home in Woods Hole, Massachusetts, before being relegated to a quiet corner of a yard, no longer the focus of the family's summer. Restoring the sailboat was both an act of respect and an homage to a place and a way of life that are in jeopardy of disappearing. "Sloop" is the captivating story of Daniel Robb's education in boatbuilding, peopled by an eccentric cast of characters -- lumbermen, boatbuilders, and local artisans -- who are part of a changing and perhaps dying world. They tell Robb how to find the materials -- certain kinds of wood, fastenings, caulking, and canvas -- he'll need, which are increasingly hard to come by, and they educate him in the techniques of restoration, an all-but-lost art. Building and restoring wooden boats means an initiation into a world where life is lived simply, with respect for materials, for labor, and for the local waters. A craftsman and environmentalist, Robb is a willing and able student, and although the restoration of the boat takes far more time and effort than he'd calculated, it is ultimately successful. After all Robb's struggles with quartersawn white oak, homemade steam boxes, bronze screws, copper rivets, andold mast hoops, the Herreshoff sails again -- and a dying art and a vanishing way of life remain alive and vibrant just a while longer. By turns charming, meditative, and wonderfully quirky, "Sloop" is a paean to a sense of place and to old-fashioned values.
More than just a book about sailing, Go for the Green is a clarion call to bring sailing out of the doldrums and into an expanded role as a catalyst for the more environmentally sensitive enjoyment of the sea. As a former Coast Guard Officer, active racer, cruiser and yacht designer, author Garry Hoyt combines a lifetime of sailing experience, with a weather eye to uncover the new challenges of global warming and the need for energy independence. His prediction that carbon based fuels will eventually draw the same degree of social scorn that smoking now receives, creates an automatic need for ingenuity in the harnessing of sail and solar power as better alternatives for water based recreation. To encourage readers along that path, Hoyt presents a philosophy and a variety of new design solutions to stimulate more creative design development. He makes his case in a simple, readable style that will interest all those who love the sea.

""Always Another Horizon,"is well written and a delightful way to
spend a winter's evening or a rainy day." Full of rich detail and intriguing insight, "Always Another Horizon: A Journey Around the World" tells the story of one couple's voyage around the globe. For nearly eight years, author Tina Olton and her husband, Steve Salmon, sailed around the world on their forty-foot, ocean-going sailboat, "Another Horizon," In that time, they traveled 45,000 miles, visited sixty-one countries, and crossed three oceans as well as countless seas, canals, lakes, and rivers. From Berkeley, California, the couple cast off their dock lines to head west through the Golden Gate. The whole world was before them-the ultimate traveler's dream. From the rich beauty of French Polynesia on Easter Sunday to the whitewashed beaches of Greece, Olton and Salmon embraced the world and its diversity. But the voyage also forced the couple to examine the limits of their determination, their ability to endure hardship, their tolerance for other people-regardless of behavior or beliefs-and their good will toward each other. Olton and Salmon soon realized that the journey would have a profound impact on their lives-or bring them to their knees. For maps and photos, see www.AlwaysAnotherHorizon.com.
