The Pearson Commander is, in many respects, a scaled-down version of the Triton, and a larger version of the Ensign. It boasts a very large cockpit, which makes it ideal for daysailing. The cabin is somewhat spartan, unlike the Pearson Ariel, which is a cruising version of the Commander.
Carl Alberg owned a Commander himself, in his final years as a sailor. He kept his hull #302 in Marblehead Harbor, Massachusetts, and belonged to the Boston Yacht Club, where he served as an officer on several occasions. Hull #302 was named after his wife, "Alma". (One of the launches at the Boston Yacht Club is named "Alma" today, in the Alberg's memory.) Mr. Alberg sold his Commander to his friend and fellow club member, Mr. Gene Collard in 1974.
Mr. Collard renamed the boat, "Hot Spur", and sailed her until 1979, when she was purchased by Mr. Tim Risk and renamed "Out a Gear". Hull #302 was purchased by Dr. Jack Mallett in 1985, and moved to his home harbor of Padanaram, Massachusetts. In 2002, Dr. Gil Stillings acquired "Acadia" (the name Dr. Mallett had chosen), and she now resides on the Kickemuit River in Bristol, Rhode Island -- just a few miles from where she was built and within eye sight of Mr. Everett Pearson, co-founder of Pearson Boats.
