Peter A. Ibold (born August 1, 1936), is an American naval architect.


Biographical Summary *

Born August 1, 1936 . United States/France

At the end of the last century, naval architecture saw the traditional look come back in force. Peter Ibold is one of the founders of this trend, with one of the earliest examples being his 1970 design for the Endurance-35, drawn the year he founded his naval architecture office in Paris.

Born in Cincinnati, Ohio, Ibold grew up in Connecticut. His study of civil engineering, town planning, and economics took him successively to the University of Maine (BSc), University of California at Berkeley, and Stanford University (MSc). An around-the-world trip in 1964–65 aboard a 12-meter trimaran, a first for that time period, was an adventure and a revelation for Ibold. It led to a contract with National Geographic.

Starting out as a hobby, naval architecture became a passion for Ibold. In 1970, his design for the Endurance 35 won competition. Encouraged by an enthusiastic press, he put together his own design office. The office moved to Monaco in 1977 and then back to the French Riviera in 1990 before he finally settled back in Paris in 1993.

Over the years, Ibold has designed more than fifty vessels, including powerboats, sailboats, yachts and workboats. They have been built in a number of yards, such as Belliure in Spain, Stratimer in France, and Colvic Craft in Great Britain. His collaboration with Belliure has been most fruitful. His greatest successes continue to be the Endurance series, with more than one hundred and fifty 35-footers, forty 40-footers and about thirty 30-footers launched to date by Belliure alone.

For several years, Ibold lived on a Dagless Fleur de Lys, an English motoryacht. He has designed the motoryacht Albacore series (7 to 10 meters) as well as many other motoryachts.

Peter Ibold retains a love for all things concerning the sea, including his involvement with several foundations and maritime associations - a happy legacy of his round-the-world trip.

The Ibold office is in Paris, France. --Dominique Gabirault
