Oar

Implement used for rowing – propelling a boat without the use of sails or engine. Usually used in pairs. The difference between an oar and a paddle is that the former is
generally longer and that it is used in conjunction with a fulcrum such as a
thole pin or a rowlock. The paddle is supported solely by the arms of the
paddler. An oar has a Shaft, with a Blade at one end and a Loom at the other
for the hands to grip.
