Design and Materials of Rowing Oars

A rowing oar is used to push a boat through the water. It is a simple tool that has been around for thousands of years. People used row boats long before cars, trains, and planes were ever invented. Throughout history, prisoners rowed ships at their captive's command. Today, rowing is used to reach a destination, compete in sporting events, and as a form of relaxation. The basic oar design hasn't changed much over the years, but the materials have been updated.

A Simple Tool

There are 5 required parts to an oar. It has a handle located at the top, and a blade at the bottom. In between are the sleeve, collar and shaft. Novices at rowing might prefer to use a T-grip handle, so that their hand doesn't slide off the end. Grips are available for this purpose also. They are made of many materials, and can be individualized for each athlete. Grips need to be kept clean to maintain a firm grip.

A collar is on the sleeve of the oar, which is located just below the handle. The collar helps keep the oar from slipping into the water. Oars are different from paddles because they are actually secured to the boat. Outriggers are attached to the sides of the boat, and the handle fits through them, attaching the oar to the boat.

The shaft is located between the sleeve and the blade. Standard shafts are straight, but bent shafts have become more popular in recent years. Shafts provide the length of the oar. It is important to make sure oars are the right size for the rower using them. Bent shafts attach to the blade at an angle. They help with the aerodynamics of rowing. Below the shaft is the blade.

Types of Blades

Blades are the most important part of the oar. When rowers carry their oars, they always protect their blades. If a blade gets damaged, its effect in the water is diminished. There are two main types of blades.

1. Conventional Blade: This blade is rectangular in shape, and squared off at the end. It is usually short and flat. Conventional blades push through more of the water, and require more work when performing the stroke.

2. Beavertail Blade: These blades resemble a beaver's tail. They have a round end, and are longer and narrower than conventional blades. Beavertail blades are great for competitors because they allow for short, quick strokes.

Materials Used to Make Oars

Oars were originally made from wood. Wooden oars are shaped, varnished, and laminated, and can be customized for the oarsman. Many athletes prefer wooden oars because their blades are strong and light weight. Depending on their quality, they can cost several hundred dollars.

Aluminum, fiberglass, and plastic can be used together to make oars. These materials are sturdy, and difficult to damage. Oars made from these materials are inexpensive, and are great for people who are new to rowing.

Oarsmen who want to travel down the rapids, or cruise to Olympic victory in a row boat, depend upon the materials and design of their oars. This is the tool they rely upon to gain momentum through the water. A good athlete can achieve great things by choosing the perfect oar.
