0 a U-shaped device or hole on each side of a rowing boatin which the oars (= poles with flat ends used to move a boat) are held --
One of the west-facing windows on the second floor has two rowlock arches above it; the other second-floor windows are rectangular.
For a 7 feet oar the balance point is about 12 inches outboard of the rowlock.
The oars did not use rowlocks or thole pins but square holes cut below the gunwale line.
The boat had no facility for rowlocks and oars.
There are three rowlock arches above all of the windows on the first floor.
Sometimes on narrow, faster rowboats for protected waters outriggers are added to increase rowlock separation.
As the position of the rower's centre of gravity changes, the force exerted on the stretcher, seat and rowlock is monitored.
The boat was supplied with an additional thwart and rowlocks for use when under power and rowing.
