After years of researching, building and testing many designs, Charlie Mathys has found the answers to inexpensive "Electric Propulsion for Boats." This book starts with an overview of his successes and failures. With each success Charlie moves ahead until you have an excellent understanding of electric propulsion for boats. This book delves deeply into the technical aspects of electric propulsion. However the information remains extremely easy to understand. The book will take you through each phase of the required work thoroughly, with detailed explanations for each step along the way. You will not find another book that explains all aspects of this subject so completely or in such an easily understood format. Although Charlie has limited the examples to smaller boats, the processes can easily be modified for larger vessels. If you have an interest in quiet, clean and green propulsion for your boat, this book is the perfect place to start your project
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.
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.

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.
The early development of the screw propeller. Propeller geometry. The propeller environment. The ship wake field, propeller performance characteristics.
A guide to nearly 1,000 sailing routes covering all the oceans of the world, geared specifically to the needs of cruising sailors. It advises on the winds, currents, regional and seasonal weather, and optimum times for individual routes, plus over 6,000 waypoints.
Throughout most of the twentieth century, electric propulsion was considered the technology of the future. Now, the future has arrived. This important new book explains the fundamentals of electric propulsion for spacecraft and describes in detail the physics and characteristics of the two major electric thrusters in use today, ion and Hall thrusters. The authors provide an introduction to plasma physics in order to allow readers to understand the models and derivations used in determining electric thruster performance. They then go on to present detailed explanations of: Thruster principles Ion thruster plasma generators and accelerator grids Hollow cathodes Hall thrusters Ion and Hall thruster plumes Flight ion and Hall thrusters Based largely on research and development performed at the Jet Propulsion Laboratory (JPL) and complemented with scores of tables, figures, homework problems, and references, Fundamentals of Electric Propulsion: Ion and Hall Thrusters is an indispensable textbook for advanced undergraduate and graduate students who are preparing to enter the aerospace industry. It also serves as an equally valuable resource for professional engineers already at work in the field.
Work smarter, not harder. The first guide to truly holistic health and fitness for those in their 40s From Tom Brady to Serena Williams, Tiger Woods and Roger Federer athletes are increasingly peaking later in their careers. Let Dr Marc Bubbs be your personal trainer in this accessible guide— aimed exclusively at those in their 40s. Create a customized program that works for YOU—from diet, to sleep, type of training and mindset, this book has all the tools you need. Peak 40 is for anyone wanting to rediscover the best version of themselves coming into their 40s. Author Dr Marc Bubbs is a performance nutritionist with a portfolio of professional and Olympic athletes - but he is also the dad of three girls, all under 7!

For fans of Joe Wicks and Michael Mosley, Dr. Bubbs offers simple, evidence-based and time-efficient strategies to help you reignite your energy and passion. His realistic, grown-up and non-judgemental approach is to explain the effect some food groups and lack of exercise and sleep have on our body. The information presented is easy to digest and he offers advice that can be tailored to your body and personality type. In his expert opinion, small changes such as ‘not eating after 8pm for five out of seven days’ can have a big impact on weight loss and positive mood. Rather than eliminating certain food groups like fats and carbohydrates, he looks at ‘turning the dial’ on them depending on individual needs. If life has become too sedentary, he provides ways to increase suppleness so that you can start to reintroduce movement into your life without causing pain. Guiding us through the myriad of confusion lifestyle messages, Dr. Bubbs teaches us: How to increase flexibility How to train with achy joints, knees, back, shoulders... Whether a plant-based diet is right How to maintain bone health Whether to lift weights Who should do HIIT (and who shouldn’t) The importance of glucose control in your diet Advice on dealing with anxiety and low mood How to set realistic expectations "[Bubbs] dives into the nutrition and science—where it’s been and where it’s heading."—Zack Bitter, world record-holding ultra marathoner, as heard on "The Joe Rogan Experience" "Dr. Bubbs's advice on nutrition, health, and recovery for peak performance has been a game changer!"—Kevin Pangos, point guard, Barcelona FC Basketball
