The Thole Thing is a nautical term referring to the oarlock, which is a device used to hold an OAR in place while rowing. It is also known as a thole pin or thole. The oarlock is usually made of metal and is attached to the side of a boat, allowing the OAR to be inserted into it and held in place. The Thole Thing is an essential part of any boat's equipment, as it allows the rower to have control over the direction of the boat.
