Weems & Plath Celebrates its 95th Year

It all began with The Weems System of Navigation

In 1928 Captain Philip Van Horn Weems, a graduate and instructor of the U.S. Naval Academy, and his wife, Margaret Thackray Weems, founded the Weems System of Navigation. At the Annapolis-based navigation school students could choose to receive correspondence or in-person courses to learn how to navigate in the air and at sea.

Weems quickly evolved the company into manufacturing navigational instruments that could be used in tandem with the courses. Courses continued to be offered through the mid-1970s when the company decided to focus more of its attention on further enhancing navigation by serving as a consultant for the U.S. Navy and U.S. Coast Guard.

Updated versions of some of the instruments developed by the school 95 years ago are still among the most popular products sold by Weems & Plath today, including the Weems Parallel Plotter (#120), 12-inch Parallel Rule (#140), and Hand Bearing Compass (#2005).

Partnership with German compass manufacturer, C. Plath

Weems System of Navigation didn’t officially become Weems & Plath until 1953 when Johannes Boysen of the German compass manufacturer, C.Plath, partnered with Captain Weems to sell C.Plath sextants and compasses in the United States.

Weems & Plath now offers over 400 products with customers hailing from all around the world.

“We owe it all to our loyal customers who have continued to put their trust in our products, whether it be for recreational boating, military vessels, or commercial industries,” said Michael Flanagan, president of Weems & Plath. “That’s why we have continued to keep our customers at the forefront of our thoughts when developing new products.”

The company’s latest line of products is the OGM Series of LED Navigation Lights, which are built at the company’s Annapolis headquarters, using solid milled aluminum and the latest electronics to be among the most reliable, durable, and brightest navigational lights on the market.

The annual Weems & Plath Tent Sale during the Annapolis Boat Shows

See the impressive power of these remarkable lights on display at Weems & Plath’s booth in Tent C at the Annapolis Powerboat Show October 5-8 and Annapolis Sailboat Show October 12-15. During both shows, attendees can take a free shuttle, provided by Weems & Plath, to and from the show to the company’s headquarters at 214 Eastern Avenue to shop at the annual Tent Sale. For more than 30 years, this popular event has offered deep discounts on discontinued, overstock, and sample items, including navigation tools, clocks, barometers, lamps, binoculars, compasses, exquisite gifts, and even garden accessories.

In keeping with tradition, Weems & Plath will donate 10 percent of all sales on Saturday, October 14 to a charity dedicated to giving back to the local community through boating practices. This year’s recipient will be the Roslyn and Leonard Stoler Center for Advanced Medicine at the future home of University of Maryland Greenebaum Comprehensive Cancer Center (UMGCC) in honor of the Maryland Cures Cancer Regatta: one of three regattas, along with the CRAB Cup and Hospice Cup, which make up the Triple Crown of Charity Sailing, a fundraising and sailing trophy sponsored by Weems & Plath.

Flanagan said, “I think Captain Weems would be proud of how his company continues to grow and give back to the local community. We work hard to produce, as he once said, innovative products that are rooted in tradition. We look forward to celebrating our 100th anniversary with the community in the years to come.”
