In Fast Powerboat Seamanship, one of the world’s leading authorities on high-speed piloting and navigation shows you how to operate any fast boat for maximum thrill at minimum risk. Dag Pike describes the effects of hull design on performance and gives you a better understanding of how your boat is built. He explains how fast boats respond under a variety of conditions, and he walks you through everything you need to know about engines, propulsion systems, trim tabs, and the other controls that give you complete command of your craft. Pike provides a step-by-step tutorial in the techniques of fast-boat driving and spells out the measures you can take to ensure comfort and safety for yourself and your passengers. He also explores the things you need to know about the sea itself: how waves are generated, how they move, and how to assess and adjust to changing conditions on the water. You’ll learn how to adapt to the faster pace of events at 25 to 100 knots; navigate at high speed; and control a high-speed turn. You’ll also learn techniques for avoiding collisions, operating in extreme weather, and much more. The better you understand your boat and how to control it, the greater the pleasure you will get from high-performance boating. Fast Powerboat Seamanship is the source for the specialized knowledge and skills you need to get the most out of any fast boat.

How a sextant works and how to get the most out of it. The sextant is the treasured navigational device of generations of seamen and airmen. It enables position to be determined with good accuracy for ocean navigation, and it was the combination of sextant and chronometer that allowed safe navigation of the oceans for generations of seafarers. Despite the accuracy and ease of use of electronic navigation systems, every navigator should be able to use a sextant. It could even save your life in the event of electronics failure. This book describes how a sextant works, provides practical tips and advice on using it, explains how to read as well as take sights, how to make adjustments and correct errors, and finally advises on how to handle and care for the instrument. Originally written by the late Captain O M Watts, this new edition has been entirely rewritten by Dag Pike, a seaman and navigator of great experience. He is perhaps best known as the navigator of Virgin Atlantic Challenger on its successful record attempt. 'An enormously useful guide' - Fishing Boat World

Boats are expensive and they are complicated - unless you are going to pay a professional to carry out a survey (at yet more expense) it is invaluable to be able to:- quickly assess a potential purchase for signs of trouble without paying for lengthy reports- carry out a detailed check on your own boat the end of the season- identify problems and get them dealt with before they get serious- get to know your boat in a lot more detail, so if a problem develops at sea you will be more able to copeOrganised into chapters covering: Tools of the trade (basic tools, moisture meters, fingers and feel, smell, mirrors, sources of information); Checking the hull (including wood construction and rot, GRP laminates, osmosis, metal construction, keels, anodes); RIBs and inflatables; Engine and systems; Stern gear; Plumbing; Mast and rigging; Electrical systems; Interiors; Safety equipment. At the end of the book there's a handy guide to carrying out a five minute survey - invaluable when making a quick assessment of a potential purchase.Highly illustrated, with anecdotes and hands-on advice throughout, this practical book gives readers the tools to do much of the work on their own, and know when to call in the experts.

Set to become the bible for powerboat owners and operators for years to come, this long overdue analysis and review of modern powerboat design and operation explores how powerboats have developed, why, and how design impacts on control and performance.Every aspect of the powerboat’s design is considered individually and as part of the whole. Different hull designs, including multihull and foiling craft, are assessed for their benefits and drawbacks. Engine types (whether petrol, diesel, electric or hybrid) and their influence on performance are examined and the nature and impact of different propulsion systems and driving controls is also discussed.All factors that influence operation are featured, from how to optimise performance in varied sea conditions, matching speed to sea state, as well as tackling various common and uncommon scenarios (from driving into an inlet to coping with tidal races and harbour manoeuvring) as well as issues relating to crew safety.For this book, Dag Pike – the world-renowned guru on powerboats – attracted contributions from many of the top international powerboat designers, providing a wealth of expert knowledge and specialist insights about modern powerboats.The sum of their knowhow makes this book a gem of acquired knowledge, and as such will be essential for all powerboat owners, operators and designers, whether in the leisure, commercial or military sector, and it will help ensure all prospective owners get the right boat for their requirements.

Today travellers by land, sea and air take accurate navigation for granted but it was not always thus. The author, a highly experienced sailor, sets out to record the development of navigational techniques from the earliest time, five millenniums ago. As explorers started to venture offshore into the unknown they had to rely on the sun and stars for direction. From this pioneers turned to mathematics, astrolobes, sextants and increasing accurate clocks to measure latitude and later longitude. More recently major breakthroughs with electronic navigation, GPS and other satellite systems have revolutionised travel. Focusing primarily but not exclusively on marine navigation, the author weaves a fascinating course through the successes and failures of mankind's quest to explore his world. The result is a thoroughly entertaining and informative work which has no rival.

Though contemporary sailors generally use electronic systems to orient themselves, the sextant is far from redundant. This purest of all nautical instruments, which allows seafarers to accurately determine their global position alone and without the aid of modern technology, is still required equipment on all commercial trading vessels; should electronic systems fail, a sextant can make the difference between disaster and survival. In this invaluable tutorial for beginning navigators, Pike clearly and efficiently explains the use and care of the sextant.

Hidden Harbours of Wales is a tour of small and infrequently visited harbours on the Welsh coast, starting from Lydney on the River Severn and finishing a world away at Connah's Quay on the River Dee on the north coast. 'Hidden harbours' vary from defined ports enclosed by breakwaters to small quays and landings. Most have a long history, often involving speculation by local landowners in the days before railways, when the coast was the best means of communication. Many of the harbours described in this attractive tour date from the 18th and 19th centuries, a time of expanding trade in coal, ore, grain and stone and industrial growth; and having been little used for decades have acquired an attractive and, in some instances, even haunted atmosphere. For each harbour there is a fascinating round up of the history and notes on what is to be found there. The author's photographs capture the scene and annotated aerial photographs assist with pin pointing harbours hidden along the Welsh coastline and its estuaries. This is the second in the series and complements the author's Hidden Harbours of Southwest Britain

This comprehensive and authoritative guide to practical navigation draws on the author's extensive experience of leisure cruising and ocean racing.

Hidden Harbours of Southwest Scotland is a lively tour of small and infrequently visited harbours on the stunning Scottish coast and its nearby islands, starting from Port Logan in the south and meandering northwards to Lerags on Loch Feochan in the Firth of Lorn.
