Bob Sherwood

GUE Recreational, Technical, & CCR Instructor
GUE Instructor Trainer / Instructor Evaluator
USCG 100 Ton Master Captain

Bob has more than 30 years of experience as an exploration diver, educator, and instructor trainer and is considered by his peers to be one of the top dive professionals in the World.

Bob worked closely with Jarrod Jablonski during the formation of GUE and is a member of the GUE advisory board and the only GUE Instructor Trainer/Instructor Evaluator in the Northeast United States and Canada. He is the founder of the GUE affiliate Northeast Underwater Explorers.

As a member of the Woodville Karst Plain Project (WKPP), Bob was a support diver for Jarrod Jablonski and George Irvine on their world record cave dive of 18,000 feet at a depth of 300 feet. In 1999 Bob was a member of an elite team of divers on the prestigious GUE expedition to the wreck of the HMHS Britannic (sister ship of the Titanic) located in approximately 400 feet of water off the coast of Greece. This project included the first extensive penetration into the wreck.

In 2011, Bob initiated and led a project to document the condition of the wreck of the A. E. Vickery, a popular dive site in the St. Lawrence River. This NEUE project is also supporting the efforts of Project Baseline.

Bob continues to share his passion for exploration, teaching, and community-building with divers from all walks of life, from professional athletes to open water divers, in the United States and abroad. Bob’s reputation as an accomplished dive instructor has resulted in invitations to train divers in Egypt, Italy, Russia, Slovenia, Japan, the Philippines, and Mexico. Students trained by Bob have gone on to become exploration divers, scientific divers, and GUE instructors.
