Developed within the ship building industry
escape_hatch.gif (16668 bytes)The Vancouver company had its beginnings in 1946. Founder John Manly built small commercial vessels, expanding into steel and aluminum construction of fish boats, tugs and patrol vessels. Early in his enterprise he observed problems with the marine closures of the day and applied himself to the development of better designs. His objective was to produce closures that were impervious to extremes of cold and heat, and were rugged and watertight. His first solution was a sandwich construction of aluminum laminated to a cedar core, closed by a quick-acting single lever.

He went into production, first of all to equip his own vessels and then for clientele in British Columbia and beyond as the excellence of his product became known.

Lasting quality and security
Today, Manly doors, windows and hatches are a standard in the industry, carrying forward the tradition of innovation and high quality. They are relied upon by conscientious builders of workboats, tugs, fishing vessels, freighters, tankers, passenger vessels and ferries.
