The German edition of the book is being discontinued by the publisher.David Barrie (born 1953) is a butterfly researcher, chairman of various foundations, passionate sailor and great author with great enthusiasm for navigation topics.With his first book "SEXTANT - A voyage guided by the stars and the men who mapped the world's oceans" he succeeded in creating a successful mixture of adventure, science, mathematics and heroic deeds. Above all, however, the book is also a declaration of love for the sea. "Barrie ties everything together in a light, airy way, surprises with historical detail, pays tribute to the courage of the first seafarers setting out into the unknown and brings tragic fates out of the mist of the past," a review said.Barrie describes how unknown the outlines of entire continents were just 250 years ago. Orientation by the stars was considered imperfect. Only a new observation instrument gave the modern world its shape: the sextant. David Barrie tells the story of how and why it was invented, how vital it was for seafarers and what a central role it played in the history of exploration and discovery.He artfully combines the experiences of intrepid seafarers such as James Cook, La Pérouse and Joshua Slocum with memories of his own Atlantic crossing, which he undertook as a young man.352 pages, 12.2 x 18 cm, paperback. German edition. English edition.
Template for celestial navigation created by RYA Yachtmaster Ocean Instructor Leon Schulz in cooperation with the German sextant manufacturer Cassens & Plath.The clearly laid out DIN A4 sheet has proven itself in theory and practice and has helped hundreds of sailors to quickly understand, with helpful designations, information and notes, where in the sight reduction tables and Almanacs which values must be taken step by step.These are not only helpful for understanding celestial navigation, for example during an RYA Yachtmaster Ocean course, but above all as a later memory aid. The templates are clearly structured and provide step-by-step instructions on how to determine your own position.There is a template for observing the sun and one for determining the noon latitude.Each pad has 25 sheets (printed on one side). Texts in English.The free instructional videos on how to use the templates on Leon Schulz's homepage help you to familiarise yourself with the working method.www.reginasailing.com/celestial_videos/
Lutz Böhme has been working for over 15 years for various sailing and sports boat schools in the training of sailing licences for the German certificates of competency Sportseeschifferschein (SSS) and Sporthochseeschifferschein (SHS).He has therefore compiled his various explanations, instructions and exercises on 135 pages for easy-to-understand, well-founded exam preparation.In the terrestrial navigation section, he goes into particular depth on the content above the Sportküstenschifferschein (SKS), for example by describing current triangles lasting several hours.The topics of tidal science and calculations with the Admiralty Tide Tables (ATT) and electronic navigation are also covered. The chapter on shipping law also includes radar plotting and the evasive manoeuvres required for the SHS.A very helpful script in ring binder form.The reading sample - see further down on this page under "Downloads & Information" - gives a good first impression (even if it is not from the latest edition).135 pages, numerous photos and illustrations, DIN A4 format, edition: February 2024. German edition.

The artificial navigation horizon is required to measure the celestial altitude with the sextant when there is no horizon visibility, for example at night, in ground fog, when travelling under land or for land navigation.The artificial horizon can be used on all CASSENS & PLATH sextants that are equipped with illumination because it requires a power supply. These are the sextant models Horizon Ultra, Polaris, Bobby Schenk and Professional (with illumination).The artificial horizon can be easily exchanged for the normal sextant telescope thanks to its clamping screw. No adjustment is necessary.The device is used as a normal sextant telescope (3 x 25 mm) with a bubble level inserted into the optical path. A crosshair and the dragonfly bubble appear against a red illuminated background. A dimmer allows the brightness to be optimally adjusted to the external light conditions. An additional shade glass can be attached to the lens for solar observations.The artificial horizon is suitable for navigation and is approved for commercial shipping under BSH/047/01/78.For purely training purposes, the artificial training horizon (Article-No. 3716-113) is an inexpensive alternative.
