Fins and Rudders


Most people know that rudders and fins are paddlecraft parts, but how many really know what they are for? Both can add to the paddling experience, but there is a high level of personal preference involved. Here we share the basics, so you will have the information you need to make your own choices when purchasing.

A rudder is a blade attached to the stern of the kayak, usually by metal cables. It is controlled by foot pedals, and can stay straight to help with tracking (maintaining a straight course) or pivot to help you turn your vessel. Rudders can often be raised and secured when not in use.

Most kayaks do not come with a standard rudder, because it is possible to turn using just your paddle, but some longer boats designed for touring long distances may have a permanent rudder. Keep in mind that while a rudder will make turning easy and can leave your hands free for things like fishing, photography, or eating, you will sacrifice forward momentum with each pivot. We recommend a rudder for beginner to intermediate paddlers paddling in open water in windy, rough conditions. More skilled paddlers with efficient strokes may have less need for a rudder.

Stand up paddleboards will usually come with fins as standard equipment, but fins are usually customizable and can be changed to suit your needs. Like rudders, fins help with stability and tracking. They can also affect speed and your ability to turn. In general, the more surface area a fin has, the more stability it will offer. With a larger fin, you will usually sacrifice speed and maneuverability. Smaller fins are faster and easier to turn.

Fin shape is closely related to performance, and there are a variety of shapes and configurations available. Some paddlers prefer one fin, while others use two, three, or even four. It is possible to own multiple sets for different situations.

When choosing a rudder or fins, the most important thing to keep in mind is your paddling lifestyle. It is always best to consult with an expert at your local paddle shop, who should be familiar with the local waters and paddling conditions. They will also know what will complement your paddling style, what is available for your specific vessel, and how to position fins and rudders for optimal performance. Always try before you buy, if possible. Ask if there is a demo day coming up when you might be able to test various equipment before you invest. Happy paddling.
