Reg Freeman was a British naval architect who designed various types of boats, including the Seadog 30 ketch. He was born in 1910 and started his career as a draughtsman for the Royal Navy. He later worked for several yacht builders and brokers, such as Camper and Nicholsons, Moody's, and Hillyards. He also designed some of the early Hallberg-Rassy yachts, such as the Rasmus 35 and the Monsun 31. He was known for his innovative and versatile designs, which ranged from motorboats to sailing yachts, and from small cruisers to large ocean racers. He also had a keen interest in traditional wooden boats and classic yachts, and wrote several books and articles on the subject. He was a founding member of the Old Gaffers Association and a long-time supporter of the National Maritime Museum. He died in 1999 at the age of 89, leaving behind a legacy of over 300 boat designs and a wealth of maritime knowledge. He is remembered as one of the most influential and prolific British yacht designers of the 20th century.
