Tri-State Marine & the Annapolis School of Seamanship – a modern boating partnership providing you with a unique combination of skill, expertise & access enabling you to safely enjoy your time on the water.

When the Annapolis School of Seamanship were looking for a fleet of new boats to conduct their summertime on the water training, they had only one boat manufacturer in mind  — Grady-White. With the highest level of customer satisfaction, industry leading safety, quality and reliability, superior design innovation and enviable overall performance, it’s no wonder why Grady-White was their top choice. It was then a logical decision to contact Tri-State Marine, Maryland’s #1 Grady-White Retailer for more than 40 years with an average customer satisfaction of 98%.

“When I first met with the team at Annapolis School of Seamanship on their idea of a partnership, I quickly saw the potential of combining their top quality instruction with Grady-White — in a way that only Tri-State Marine could deliver,” says Keith Rhodes, owner of Tri-State Marine on the partnership. “Expert instruction and boating safety has always been a top priority of ours, so you can imagine how excited we are about providing ASOS with new Grady-White boats for use in their on-the-water courses. It’s really the very best teaching aboard the very best.”

The unique partnership enables not only course participants to learn aboard a Grady-White, Tri-State Marine also provides new boat discounts to course graduates, including free instruction with ASOS with the purchase of every new boat. “It’s really incredible to think how two top Maryland maritime small businesses can combine in a unique way to the benefit of so many Chesapeake Bay boaters. We’re thrilled with our partnership with Tri-State Marine and we look forward to working with the team for many years to come – including the potential of expanding to new locations,” John Martino, owner, Annapolis School of Seamanship said of the new partnership. “Keith and the team there are great to work with, and now it’s even more exciting that they have a new location at Bert Jabin’s Yacht Yard on the waterfront in Annapolis. That makes it even better!”

About the Grady-White 180 Fisherman 

Grady-White’s 180 Fisherman is the best center console boat under 20-feet, offering numerous features and creature comforts not found on other boats its size. From the 11-gallon livewell to storage for up to 12 rods, the 180 is fishing ready but quickly transitions for family boating. A swim platform with port side ladder offers easy access to and from the water, and an optional ski pylon makes it perfect for water sports. Built on Grady-White’s award winning SeaV²® hull, this is the best riding 18-foot boat!

Given this, it makes perfect sense why the renowned Annapolis School of Seamanship has chosen not only Grady-White, but this particular model for use in their programs. “It’s really the perfect small boat — though I’m reluctant to call it small — since it handles better than most other larger boats. Take it from our captains who spend their days on the water, a better riding hull and overall level of craftsmanship make a huge difference while spending days on end on the water. There is simply no better boat for us for these programs,” said John Martino, Owner, Annapolis School of Seamanship.
