Built in 1892:
+++++++++++++++++++++++++
Tug ISLAY was built by Alexander McDougall and named for his daughter, and
she in turn, named for McDougall's birthplace in Scotland. The tug was part
of the first triple launching on the Great Lakes, which included the
uniquely designed Whalebacks, the Pillsbury and Washburn. Powered by a
1-cylinder,125 HP steam engine and held by the yard until 1911, the tug went
on to a career of supply boat and lumber tug. Converted to diesel and
renamed Bayfield in 1949, she worked around the Apostle Islands and
Chequomegon Bay of Lake Superior. On the St. Claire River in the mid-50's,
BAYFIELD served in the marine construction business. Moved to Lake Michigan
in 1972, she finally laid up in 1976. Reactivated in 1989 with second hand
Kahlenberg Diesel, ISLAY has made a brief appearance at the Port of
Milwaukee, Wisconsin.

One cylinder @ 125 hp!

Cool

So how would you guys over there pronounce the boat's name? Over here
on the west coast of Scotland the island it's named after is pronounced
'eye - la'. Home of more whisky distilleries than you can shake a stick
at.

Not to be confused with internal combustion engines. Apples and
oranges.

The largest ever single cylinder steam engine was designed by mathew
Loam of Cornwall and built by the Hayle Foundry Co. in 1849 for land
draining at Haarlem, Netherlands. The cylinder was 3.6 m 12 ft in
diameter and each stroke also of 3.65 m 12 ft, lifted 61.096 liters
13440 gal of water.


And if you notice, this 150 hp only had a 16" bore, 30" stroke: They
did, however need huge flywheels!

This engine was designed and built by the William A. Harris Steam
Engine Company, corner of Park and Promenade Streets, Providence, RI.
It has a 16" bore and 30" stroke. It has a Tangye bed and Brown Valve
gear. William A. Harris was the plant superintendant at the Corliss
Steam Engine Company until 1869, when the Corliss patent ran out. He
then started his own company using the Corliss valve design. This
engine was first installed in a shoe factory in Brockton, MA in 1911

An interesting article concerning steam engines (Stanley Steamer Cars) that
partially explains horsepower of steam engines. Don't know whether it
applies here or not.
