2006 American Tug 41

SEAGLASS is a well maintained and significantly upgraded American Tug 41, one of the most popular and iconic trawler-style cruisers ever built. These tugs famously shuttle their owners around some of the most intense cruising grounds that the Pacific Northwest has to offer, while simultaneously making a name for themselves as a comfortable, efficient, easily handled Great Loop vehicle. The versatility and stability of a trawler-style hull, coupled with the mid-teens speed potential when the need arises, sets these tugs apart from their peers. SEAGLASS has benefited from a storied history of ownership, with back-to-back meticulous operators who spent silly sums of time and money updating and upgrading nearly every system on the boat. No expense has been spared and no bilge left untouched, with 3+ years' worth of consistent oil samples along with >$300,000 in service records and refit invoices available upon request. Simply put, SEAGLASS is arguably the best-kept and most upgraded example of the AT41 that has come to the market in years and needs absolutely nothing – she is in the water and turnkey for a Great Loop adventure! 

• Over $250K spent on a major refit by her former owner in 2018-2019  
• More than $50K spent on recent upgrades and major service under current owner 
• Nearly all service records, invoices, and oil samples reports are logged and available  
• More than 1,000 of her engine hours were run in fresh water (Great Loop) 
• The current owner added 347 hours in New England waters, where she was used for 4-5 -months per year and stored under cover each winter 
• The current owner added freshwater flush kits to the engine and genset sea strainers and flushed with fresh water after each use

CONSTRUCTION

The American Tug 41 is constructed with hand-laid, hand-rolled rove and resin laminate hulls. The bottoms are solid fiberglass reinforced plastic (FRP), with coring used above the waterline for additional strength, insulation, and sound attenuation. The molded frames and stringers are constructed as a single, unified matrix and then glassed into the hull to ensure maximum strength, structural integrity and durability.
