Crab Decks & Tiki Bars of Chesapeake Bay and Marinalife are holding the inaugural Big Bay Hunt, which takes place today through Sept. 1.

People across the Mid-Atlantic region are invited to unravel a centuries-old maritime mystery based on a recently unearthed diary of a sailor named Matthew Clement Henry. Participants can follow in his footsteps to decipher cryptic messages from the pages of his diary and figure out what he was seeking on the Bay.

From Memorial Day to Labor Day, boaters, families and people with a thirst for adventure will visit nine waterfront restaurants, bars, and tiki lounges on the Chesapeake Bay, where mysterious clues are stashed. They’ll gather clues from each location to reach one final solution. Winners receive prizes at the end of the summer.

Big Bay Hunt destinations include:

• Big Owl Tiki Bar, in Grasonville

• Bridges Restaurant, in Grasonville

• Cheshire Crab Restaurant, in Pasadena

• Hard Yacht Café, in Dundalk

• Little Havana, in Baltimore

• Passages Bar & Grill, in Rock Hall

• The Point Crab House & Grill, in Arnold

• Rowboat Willie’s Dock Bar, in Sparrows Point

• St. Michaels Crab & Steak House, in St. Michaels

“The clues are challenging and fun to figure out. It’s all about exploring many fantastic Bay destinations while enjoying a unique adventure and friendly competition,” said Susan and Bill Wade, authors of the Big Bay Hunt and the travel guides, Crab Decks & Tiki Bars of the Chesapeake Bay.

“Marinalife is excited to partner with the Wades and offer a unique challenge to our members cruising the Chesapeake Bay this summer,” Marinalife president and CEO Joy McPeters said in a statement.
