Electric propulsion for boats was developed in the early 19th century and--despite the advent of the internal combustion engine--continued with the perfecting of the modern turbo-electric ship. Sustainable and hybrid technologies, pioneered in small inland watercraft toward the end of the 20th century, have in recent years been scaled up to create integrated electric drives for the largest ocean-going vessels. This comprehensive history traces the birth and rebirth of the electric boat from 1835 to the present, celebrating the Golden Age of electric launches, 1880-1910.

There's more than one way to power a toy boat. Electric motors, balloons, gears, water jets, belt drives, chemical reactions, steam, and even gravity can be used to propel a small ship across a pool. Also, the boats' propellers and paddles can be side-mounted or at the stern, or even sit above the waterline, like a fan-powered swamp boat. The Motorboat Book will show children how to build more than 20 different models through step-by-step instructions with clear photos. And if they'd rather travel under the water than over it, the book has 6 different submarine projects. In addition to the boatbuilding activities, author Ed Sobey includes instructions on how to build an &“ocean&” to test the boats, as well as accessories such as four different water pumps, waterproof battery and motor cases, and a working foghorn. Most of the boats are built from recycled and easy-to-find materials, but an appendix lists local and online sources for wire, plastic propellers, small motors, and more. Educators will appreciate the Meeting Science Standards summary at the end of the book.
My Electric Boats is the 2nd Edition of the popular textbook Electric Propulsion for Boats. This updated version includes a new Rhodes 19/Etek conversion, plus more performance and efficiency tests, new photos and four complete step-by-step conversion chapters. Divided into three sections, the book starts with an overview of the author s successes and failures while researching basic concepts. With each success, he moves ahead until you have an excellent understanding of electric propulsion for boats. Delving deeply into all the technical aspects of electric propulsion, the book guides you thoroughly through each phase of the required work, with easy-to-follow explanations for each step. The examples and processes can be easily modified for small or larger vessels. If you have an interest in eco-friendly propulsion for your boat, this is the perfect place to start. www.myelectricboats.com --------- NEW to the Second Edition Four Electric Boat Conversions Convert a Rhodes 19 sailboat with a Lynch/Etek inboard Align the drive shaft electrically Four How-To Chapters More Performance and Efficiency Tests More Photos -------- For anyone with practical skills who wishes to get deeply involved in building or modifying boats, or experimenting with AC drives, this should be a goldmine.

A step-by-step instruction manual on how to build a lightweight 'environmentally-friendly' boat with recyclable resources. The boats simply fold up from ¼” thick cardboard obtaining their strength from the geometry of the component parts. The boats are 8-feet long, weigh about 25-pounds, and can accommodate a 250-pound person without risking structural damage. Each boat is constructed with 21-pieces of cardboard that are used to make 7-component parts. The 7 parts are assembled together with 'environmentally-friendly' contact cement and paper drywall tape. Once assembled the boats are sealed with an 'environmentally-friendly' water-based waterproof coating. No special tools are required and they are very simple to build. All of the materials used to build a boat are typically found at 'do-it-yourself' home improvement stores. The boats can be outfitted with 12-volt electric fishing motors, although they are typically propelled with traditional Kayak style paddles.

Whether out for an afternoon's sail or embarking on a long offshore passage, there is always an element of chance and uncertainty about being at sea. To be responsible for the wellbeing of both crew and vessel, a good skipper needs to know their limitations and ensure they are operating well within the margins of safety. Safe Skipper is a practical and thought provoking guide for yacht skippers of all levels of experience, full of invaluable advice and tips on how to reduce to the minimum the risks of mishaps and equipment failure at sea. There's a wide range of information on seamanship, preparation, seaworthiness, gear, boat handling, leadership, teamwork, watch keeping, communications, navigation, weather and emergency procedures, all delivered in a highly practical, lively, non-preachy fashion. Included throughout are useful checklists, box-outs and case studies of accidents and their causes, with survivors' testimonials and explanations of how disasters were avoided, or could have been, all of which provides valuable lessons for everyone who goes to sea.
In 1983, the freighter Marine Electric ran into a violent storm off the Eastern Seaboard of the United States. Despite Force 10 conditions and fifty feet waves the crew were unconcerned: the ship had survived worse. But something was wrong, the ship was beginning to break up under them; gradually it began to go down by the head, then to capsize. Within two hours the crew were in the water in a desperate struggle for their lives. Their plight sparked one of the most dramatic air-sea rescues in maritime history. Only three of the 34 crew survived the night. The ship had sunk due to a serious structural defect. The chief mate Bob Cusick discovered that the owners had lost several other ships in similar circumstances to the Marine Electric, but the sinkings had been covered up. He decided to go after the company and they in turn rounded on him, the sole surviving officer. What follows is an epic and epochal court case that left none of the participants unscarred.
