Roger Marshall's experience as a writer spans many years. Since 1973 he has been a contributor to various gardening, sailing and boating magazines in America and in many other countries. His work has appeared in the New York Times, Daily Telegraph (UK), Sports Illustrated, Sail, Cruising World, The Boston Globe, Australian Sailing, Kazi (Japan)and many other newspapers and magazines. After nine years as technical editor at Soundings, he became the editor-in-chief of Dockwalk and then the U.S. Editor of The Yacht Report. He is now freelancing for many magazines and web sites.
Marshall is also the author of fourteen marine related books and a greenhouse construction book. Five of the nautical books were selected as prime choice by the Dolphin Book Club, at the time the only nautical book club in America. His latest book Fiberglass Boat Repair Illustrated is now in bookstores and is illustrated with many of his projects.
Marshall is also a designer of boats, both power and sail. After completing a program in naval architecture at Southampton College in England, Marshall moved to the United States in 1973 to take a position at Sparkman & Stephens, Inc. in New York. He worked there as a designer for nearly 5 years and then left to establish his own yacht design studio in Jamestown, Rhode Island. As an independent designer he has designed boats ranging from 15-foot dinghies to a 55-foot powerboat and an 85-foot schooner. He was project engineer for the Courageous Challenge for the 1987 America's Cup campaign in Australia. In 1999 one of his designs was selected for inclusion in Ocean Cruising magazine's American Yacht Review.
Marshall has extensive sailing and boating experience. He has sailed at all levels including 12 meters and Admiral’s cup boats (once with the British team on Quailo III, another time for the British team aboard Prime Minister Heath’s Morning Cloud, and once with the Japanese team). He has also sailed in many world and national championships, 10 Bermuda races (twice with the British Onion Patch team), and 5 Fastnet races (twice with the British Admiral’s Cup team), and the Atlantic Challenge from New York, USA, to Falmouth, England, placing third. He has cruised on both power and sailboats in many parts of the world, especially the European, Mediterranean, Caribbean, and North American coastlines and regularly writes about his cruising and sailing experiences.
