Jay Hanson from Superior Scuba Charters and North Shore Scenic Cruises has helped the GLSPS on many projects. Jay has many years of experience as a Captain, dive shop owner, dive instructor and commercial diver.

Jay has taken a different path for the past few years and his scuba charters are no longer available. However, in 2012, Jay purchased the Wenonah which was previously used to transport people from Grand Portage, MN to Isle Royale, MI. He now offers day cruises on the North Shore of Lake Superior and is docked at the Silver Bay, MN Marina.

In Memoriam - Harold E. Rochat

Nick Lintgen  | Published on 9/4/2005
Harold RochatHarold E. Rochat, age 51, of Shorewood, died suddenly and unexpectedly on Sept. 4, 2005 boating with his son and friends on Little Trout Bay, near Thunderbay, Ontario. Harold was a GLSPS board member and friend to us all. He was also the owner/operator of charter business Superior Explorers and captain of the Amarada. His passion for life was larger than the life he was given. In Osseo MN he loved boy scouts, friends, boating and scuba diving. He was a natural actor, riveting entertainer and unique to the end. He loved his children and wilderness boating. He died with both. He played on Lake Superior above and below the water, operating dive charters at Isle Royale. He worked as an engineer with creativity and a desire to invent. He taught himself anything he wanted to know and liked to guide others. In 1980 he left Honeywell when he could no longer justify building better bombs and applied himself in medical product development. Later he combined his love of the sea with engineering at Woods Hole Oceanographic Institution on Cape Cod. Our deepest sympathies to his family -- wife, Andrea L. Oien; sons, Milo G. and Noah A. We will miss him dearly.
