[1] Seabury was famous for its steam yachts; the Gas Engine & Power Company's primary focus was on naptha-powered launches.
[2] Among other products, the combined company manufactured express cruisers, runabouts, yacht tenders, gas engines and alcohol ranges under the Speedway brand.
[3] The manufacturing facility in Morris Heights was referred to as the Speedway Shipyard,[4] and it stood along Mathewson Road, near what is today the location of Roberto Clemente State Park.
It was heavily involved in the production of small yachts and military vessels, employing as many as 3,000 skilled tradespeople to that end.
