Do I need a rudder? Seems like a simple question. But the answer involves engineering, ergonomics, mechanics and philosophy. Ask 10 anglers and you’ll get 10 answers.
Why You Need A Rudder, And Why You Don’t
We went to two gurus—pro angler Rob Choi and kayak designer Bob McDonough—for the final answer to the first question paddle anglers ask.
Bob McDonough is lead designer at Johnson Outdoors. His name is on some of the most popular kayaks on the water. When we asked if he uses a rudder, McDonough said, “Since I’m in so many kayaks, I’m all over the board.” When it comes to fishing kayaks, McDonough prefers a rudder “100 percent.”
A rudder improves tracking and slow-speed turning. “Something especially benefiting kayak anglers,” he says.
McDonough uses hanging rudders on his boats. “The rudder extends deeper into the water so it continues to turn the boat in rough conditions.”
A hanging rudder can be lifted out of the way. “Lifting and lowering the rudder can be awkward,” McDonough admits. He looks for a rudder with enough surface area to turn the kayak without being too large and increasing drag when down and wind resistance when up. One advantage of the integrated rudder, which is tucked under the stern, is it improves tracking when it isn’t turned. Integrated rudders are most common on pedal kayaks.
When purchasing a pedal kayak, consider how you will use the boat. The wide, rudder improves handling compared to a hanging rudder. Tucked under the stern, the integrated rudder will also draw less water. However, this type of rudder cannot be retracted in shallow water making it more susceptible to rocks.
I can paddle straight without having to make correctional strokes
For Johnson Outdoors pro Rob Choi, installing a rudder on his kayak was more a philosophical decision.
On one hand, a rudder will improve turning and tracking. On the other hand, the rudder increases wind resistance and drag. Choi considered the abuse his kayak takes forging through the surf, traversing shallow water and fishing in heavy structure. Some environments are too rough for a rudder.
“Paddlers who have never used a rudder will notice some drag,” Choi admits, but feels the advantages outweigh any effect on performance. “I can paddle straight without having to make correctional strokes” Choi says, which saves energy and time, especially when he’s covering long distance.
Traveling across open water with opposing current and wind will cause a kayak to veer off course or spin. Add weight, like camping gear, a livewell full of water or a hold filled with fish and the problem can be worse. “I don’t want to fight the kayak,” Choi says. Angling the rudder helps the kayak travel straight. Choi adds, “I can save my energy for paddling forward.”
Rudders help when fishing tight places, too. “When I’m casting or jigging, I can change the direction of my drift or turn my boat in the current,” he adds.
Choi wraps it up like this: A rudder will improve handling at the expense of little speed.
In the raised position, the rudder acts like a sail catching the wind and slowing or turning the boat. In the down position, the blade presents slightly more drag slowing the kayak. If you fish in rocky rivers or spend a lot of time launching through the surf, a rudder may not last long.
Remembering to lift the rudder before hitting bottom is a minor inconvenience, which could be a big deal if you’re into kayak fishing for the simplicity. Paddle long distances with a heavily loaded kayak, a rudder will save time and energy. Even compact kayaks used for short distances and tight quarters can be aided by a rudder.
So, do you need a rudder? Well, it’s up to you. We tried to steer you straight.
