A rowlock [1] (UK: / ˈ r ɒ l ə k /), sometimes spur (due to the similarity in shape and size), oarlock (American English) [2] or gate, is a brace that attaches an oar to a boat. When a boat is rowed, the rowlock acts as a fulcrum for the oar. [3] On ordinary rowing craft, the rowlocks are attached to the gunwales.
The calculations are simpler for the Class I perspective. The mechanical advantage of the oar depends on the length of the oar from the oarlock to the blade, compared to the length from the oarlock to the rower's hand(s). The further away from the oarlock the blade is, the more difficult it is to row and the more distance each stroke will move. [4]
The oarlock also allows the rower to rotate the oar blade between the "square" and "feather" positions. Also historically called 'Rowing Gate' by some manufacturers. Outboard The length of the oar shaft measured from the button to the tip of the blade. Outrigger (See Rigger) Pin The vertical metal rod on which the rowlock rotates. Pogies/poagies
Two "cleaver" sculls. The blades which enter the water are at the top of the picture and the handles are at the bottom. Note how the oar shaft connects not to the midline of the blade (as is the case of macons) but rather higher pitch, that is toward an upper part of the spoon/blade when perpendicular to the waterline.
The first step is the choice of the piece when still soft and young before the cut into quarters. Usually the centre of the trunk is cut down because of the lymphatic canal, easy to crack, and the external part, next to the bark, gets discarded for its darker colour.
To accommodate three levels of oars, rowers sat staggered on three levels. Arrangements of the three levels are believed to have varied, but the most well-documented design made use of a projecting structure, or outrigger, where the oarlock in the form of a thole pin was placed.

A tuning pin is a tuning peg with a detachable grip, called a tuning lever. The socket on the tuning lever fits over the pin and allows it to be turned. Tuning pins are used on instruments where there is no space for a knob on each string, such as pianos and harps. Turning the peg or pin tightens or loosens the string.
