Joseph Lotz Mann, founder of a school for charter boat and tour boat captains, died Saturday of congestive heart failure at his Towson home. He was 71.
Mr. Mann, who held a Coast Guard master's ticket for 100-ton vessels on inland waterways and deepwater, established Captain Joe Mann's Sea School in 1985. The school prepared prospective boat captains for Coast Guard licensing.
Mr. Mann developed his lifelong affection for the water and boats as a boy growing up in Wilson Point and later in Middle River. A 1947 graduate of Mount St. Joseph High School, he earned his bachelor's degree in 1960 from the Johns Hopkins University's McCoy College.
In the early 1950s, he owned the Pioneer House, a Hereford restaurant and tavern. He later established J. L. Mann Co. Realtors and Auctioneers in Baltimore.
From 1975 until 1985, he was public relations director for Miami-based Windjammer Cruises.
He was past president of the Maryland Beverage Association and the Maryland Real Estate Brokers Round Table.
He was a member of the Upper Bay Charter Captain's Association and the Maryland Saltwater Sport Fisherman's Association.
Mr. Mann enjoyed diving around shipwrecks and taking cruises.
He was a communicant of Immaculate Conception Roman Catholic Church, Baltimore and Ware avenues, Towson, where a memorial Mass will be offered at 10 a.m. Saturday.
He is survived by his wife of 52 years, the former Dona Gene Taylor; six sons, Michael T. Mann, Matthew E. Mann and Robert F. Mann, all of Towson, Curtis B. Mann of Canton, David S. Mann of Hamilton and Thomas J. Mann of Clarksville; and eight grandchildren.
