Click on the map above to explore the route of Positive Latitude. The map includes a track of the journey and a marker for each stop along the way.
After retiring early in 2019 and traveling the United States in their motorhome for 6 months, Mark and Sherri started searching for a boat in Florida. They looked at many boats before acquiring a Mainship 43 and re-christening her Positive Latitude.
Positive Latitude cruised the East Coast of the United States from the Florida Keys to Philadelphia and back to Florida. When Canada opened to pleasure boats again in 2022, the crew headed north again to spend the summer cruising to destinations such as Montreal, Ottawa, the Georgian Bay, and the North Channel.
During the fall of 2022, they returned to Florida via Lake Michigan and the inland rivers. Their 3 year journey totaled over 10,000 miles.
These are the stories of their adventures.
Mark and Sherri were joined by 75-lb Duke, a 7 year-old Labrador/Golden Retriever, and 25-lb Riley, an 11 year-old Japanese Spitz.
Positive Latitude, a 43-foot trawler, was built in 2007 by Mainship Corporation in St. Augustine Florida.

“A ship, like a human being, moves best when it is slightly athwart the wind, when it has to keep its sails tight and attend its course. Ships, like men, do poorly when the wind is directly behind, pushing them sloppily on their way so that no care is required in steering or in the management of sails; the wind seems favorable, for it blows in the direction one is heading, but actually it is destructive because it enduces a relaxation in tension and skill. What is needed is a wind slightly apposed to the ship, for then the tension can be maintained, and juices can flow and ideas can germinate, for ships like men, respond to challenge.”
