Jack Becker, an expert in documenting vessels for the Historic American Engineering Record (HAER), is taking RIPTIDE's lines via photogrammetry, which involves using computer software to develop a three-dimensional drawing of the vessel's lines from photography.
(RIPTIDE is at the Port Townsend Shipwright's Co-Op for repairs to her keel and strut in the area of her aft cockpit).
The office of Heritage Documentation Programs within the National Park Service administers the Historic American Buildings Survey (HABS), the Federal Government's oldest preservation program, and its companion programs: the Historic American Engineering Record (HAER) and Historic American Landscapes Survey (HALS). Documentation produced through the programs constitutes the nation's largest archive of historic architectural, engineering, and landscape documentation, and includes well over a half million documents. The HABS/HAER/HALS Collection is housed at the Library of Congress. www.nps.gov/hdp/
The Historic American Engineering Record (HAER) was established in 1969 by the National Park Service, the American Society of Civil Engineers and the Library of Congress to document historic sites and structures related to engineering and industry. Appropriate subjects for documentation are individual sites or objects, such as a bridge, ship, or steel works; or larger systems, like railroads, canals, electronic generation and transmission networks, parkways and roads.
From its inception, HAER focused less on the building fabric and more on the machinery and processes within, although structures of distinctly industrial character continue to be recorded. In recent years, maritime documentation has become an important program focus. www.nps.gov/hdp/haer/
RIPTIDE was built in 1927 by the Schertzer Brothers Boat and Machine Company, then located on the north end of Lake Union near the foot of Stone Way in Seattle. She is 47 feet 1-inch long with a beam of 11 feet 10-inches and a draft of four feet. She is planked in port orford cedar riveted to white oak frames over an apitong backbone with western red cedar houses. She displaces about 10 tons, relatively light for a boat this size.
She was originally named NEREIAD, then, shortly thereafter, NOKARE. Her trunk cabin (the raised cabin aft of the pilothouse) was reportedly added (or extended) in 1933. By 1936, when owned by Russell G. Gibson, a Director of the Seattle Yacht club, she had been named RIPTIDE.
Mr Gibson owned her through at least 1960. After a few years, she was bought in 1965 by Richard Billings, who used her as a cruiser and live-aboard in Alaska. In 1968 Richard sold her to his brother Roger, who owned her through 2014. RIPTIDE is fortunate to have been owned by knowledgeable and caring owners throughout her long life.
RIPTIDE is a Coast Guard documented vessel. She carries documentation number 226242 carved into the interior face of both port and starboard bilge stringers. She is documented at 17 net tons and 21 gross tons.
Her original engine may have been a Hall-Scott gasoline engine, but is as yet unknown. By 1959 she had an eight cylinder Chrysler Crown gas engine, a common engine of the time, most likely added in the late 1940's. That engine was removed in 1967 when RIPTIDE was re-powered by a 1967 Volvo MD-70A diesel engine. The Volvo engine was removed in early June 2015 and was replaced by Cummins 5.9 liter diesel of 210hp. While her top speed is over 14 knots at 2400 rpm, her cruising speed is a much more sedate 9 knots at 1500 rpm. She carries 300 gallons of diesel fuel.
She was overhauled by the Port Townsend Shipwright's Co-Op in Port Townsend WA between April 8th and September 16th, 2015. The Co-Op replaced 35 frames, then replanked much of her hull above the waterline. They installed a new transom and decks, replaced her engine and exhaust system, and installed a modern electrical system. Finally, a new anchor windlass and chain was installed.
Diane Salguero of Salguero Marine Services varnished the transom and pilothouse windows and painted the vessel.
RIPTIDE's hailing port is Port Ludlow WA. She is usually moored in Port Madison, on Bainbridge Island, WA.

we ordered a baked potatoe but wouldn't want any dressings. but the software of the ordering system wouldn't provide that, so hidden in some subsubnavigation there was "potatoe, with no options". still sounds odd to me.
