S.L. Artemis

to Steamboats
Artemis
is a 26' former US Navy motor whaleboat converted to steam in 1964 by Elmer Brooks. He
also designed and built the 3" + 6" x 4.5" compound engine which, at
150psi, turns the 3 blade, 23"D x 34"P propeller at 320rpm for a speed through
the water of 6.5 knots.
When George Walrod and I purchased Artemis in 1995 we replaced the original thirty year old boiler with a Winslow type watertube boiler of 75 sq.ft. It is to ASME code and certified by the State of Oregon, producing 300+ lbs. of steam per hour at 150psi, burning 2.5gph of furnace oil through a steam atomizing burner. We replaced all the original piping and controls and had the engine rebuilt.
We also refastened, recaulked, and painted the hull and superstructure, and relocated
some interior arrangements. Artemis now sleeps two comfortably; has a galley with sink and
two burner cooktop; enclosed head with chemical toilet; electric lights, fathometer, vhf
radio and other amenities - all powered by batteries and a small steam driven alternator;
and a fold up table in the aft cockpit at which one may dine, play cribbage, or drink
coffee and tell "stories".
