Yes, it is all three classes of lever depending on the point in the stroke. Your hands are the fulcrums and the oar is the beam.
If you use oarlocks then it is a first class lever with the fulcrum in the center.
If you use it as a paddle then it is a third class lever with the fulcrum as mentioned before in the hand opposite the load.

∙ 12y agoYes! Third-class. The input force is where your hands are, the fulcrum is the oarlock/rigger, and the output force is where the blade acts on the water. Good question!

A rowboat is a compound machine because it uses a combination of simple machines, such as levers for the oars and pulleys for the anchor system.

Yes, oars on a boat are a type of first-class lever because the pivot point (fulcrum) is at one end, the effort is applied at the other end where the rower pulls, and the resistance is the water pushing against the blade. The oar's position and function follow the principles of a first-class lever.
The statement is correct. The rowboat is propelled forward by the force of the oars pushing against the water, causing a reaction force from the water that pushes the boat in the opposite direction. This action and reaction pair is described by Newton's Third Law of Motion.
Oars are typically considered second-class levers, where the load is located between the input force (the rower) and the fulcrum (the oarlock).

A rowboat is the North American term for what the British term is a rowing boat. A rowing boat is a small boat propelled by the use of oars. It can be made from wood planks set in clinker (overlapping planks) or carvel (planks butted against each other and creating a smooth surface). If such small boats are made from glass fibre or other such modern plastic type materials, it is likely to be called a dinghy or pram dinghy.
