Are Sit-On-Top kayaks More Stable?

Sit-on-top (SOT) and sit-in kayak (SIK) represent two fundamental kayak styles tailored for distinct purposes. While distinctions abound between these two kayak types, they also share a number of similarities. In both variations, the upper part of the kayak is referred to as the deck, the forward section is termed the bow, the rear is known as the stern, and the underside is termed the hull. Both styles encompass bungees or deck lines on the deck, and typically incorporate rudders, skegs, and grab loops at the stern. Furthermore, both kinds of kayaks come equipped with seats and some form of foot support, whether in the form of foot pedals or footwells.

So what’s the difference between a sit-on-top and a sit-inside kayak?

Sit-on-top (SOT) kayak

Similar to the surfboard and typically used for leisure, a sit-on-top kayak is designed to allow a paddler to sit on the deck and has no “inside” column for the paddler to occupy. Indeed, the sole points of inward access on a Sit-On-Top kayak are the storage hatch openings. Everything else, including the seat and footwells, is arranged on the deck. Staying dry on a sit-on-top kayak proves challenging, as every ripple, splash, or wave reaches the paddler atop the kayak. This is because there’s no “true” cockpit to offer protection and shield the paddler.

A Sit-On-Top kayak features a seat positioned on the boat’s surface for the kayaker to sit on. Additionally, small drain holes (known as scupper holes) at the kayak’s bottom facilitate the drainage of water that splashes onto the deck. To prevent water from splashing onto the deck through the scupper holes, self-bailing scupper plugs must cover and block them. This ensures a drier ride by keeping water from infiltrating underwater through the holes.

Pros and cons of SOT kayaks

Pros:
  1. SOT offers user-friendliness, high stability, easy entry and exit, and a sense of openness without confinement. Getting on and off a SOT is simple and flexible.
  2. SOT boasts virtual unsinkability. In the event of a tip-over, it remains afloat, allowing easy recovery by flipping it back and reboarding. The self-bailing scupper holes swiftly drain any incoming water.
  3. SOT provides ample storage space, facilitating convenient access to gear. Unlike sit-inside kayaks, reaching gear is effortless.
  4. These kayaks are more comfortable for larger individuals due to their open cockpits and wide decks, which enhance stability and usability compared to SIKs.
  5. They are also more affordable than SIKs, attributed to their sleeker design, reduced materials, and easier shipping process.
  6. SOT presents a straightforward approach to enjoying activities like surfing, scuba diving, and warm water paddling. They are particularly suitable for apprehensive paddlers and families with kids who enjoy swimming.
Cons:
  1. You are guaranteed to get wet as soon as you get on water with SOT, as opposed to a SIK that allows a paddler to stay dry.

Sit-Inside Kayak (SIK)

A sit-inside kayak is enclosed and has a sitting area called the cockpit. The cockpit is surrounded by a rim where a spray skirt can be attached to keep water out. In the cockpit is a seat and foot pedals, which you can adjust to your leg length for more comfortable paddling. The cockpit also may have a backrest, armrest, cup holder, and an adjustable footrest for more comfort.

When utilizing a sit-inside kayak, you enter the open cockpit by climbing in. Once inside the hull, you position your legs under the deck and use the walls to support your knees. Subsequently, you fasten the spray skirt around your waist and tighten the fabric portion. This is to stretch the skirt material over the cockpit’s rim, effectively sealing the interior of the hull. This spray skirt serves to hinder water from splashing into the boat. This can avoid reaching your legs, allowing you to remain dry as long as you don’t capsize the kayak. For this reason, an SIK is ideal for cold weather kayaking or for paddling in areas with shorter summer seasons.

Pros and cons of SIK

Pros:
  1. You remain dry and out of reach of water because the cockpit is enclosed to stop water from splashing into the kayak. There are also no drain holes at the bottom, so the entire cockpit remains dry.
  2. More secondary stability than SOT because the cockpit is located inside the kayak, keeping you on the water line and with less risk of tipping over.
  3. More storage areas than in a SOT. If you intend to go for camping or longer fishing trips, a SIK is ideal because it has more storage areas for your gear.
Cons:
  1. You have no freedom to move freely in and out of water.
  2. If a SIK flips over, you will have to swim to the shore to drain it out.

Which is more stable, a Sit-On-Top or a Sit-Inside Kayak?

The stability of a kayak depends on its design elements, including size, hull type, boat length, and materials. Sit-on-top kayaks, with their elevated center of gravity compared to sit-inside kayaks, often feature a wider profile, resulting in greater initial (primary) stability than sit-insides. Sit-on-top kayaks are designed with a closed hull, rendering them virtually unsinkable, and they incorporate self-bailing scupper holes to drain water in case of tipping.

Sit-inside kayaks exhibit enhanced secondary stability due to their lower center of gravity compared to sit-on-tops. This heightened stability enables effective leaning and maneuvering, even in turbulent waters. The lower center of gravity also allows for narrower profiles and increased speed, making sit-insides ideal for expedition paddling and extended trips.

Boat length correlates with stability and speed: longer, narrower boats are faster but less stable, while shorter, wider boats prioritize stability over speed. When choosing between sit-on-top and sit-inside kayaks, matching kayak length to desired speed and stability is crucial. Sit-on-tops are typically used for recreation due to their broad stability, while some recreational sit-insides offer similar stability.

Recreational sit-inside kayaks have wider profiles and big cockpits for comfort. Touring sit-insides are longer and narrower with smaller cockpits, offering speed but less stability. Material and weight are also important considerations. While most kayaks are low-maintenance hard shells made of durable plastics, some use lightweight composites like Kevlar and carbon. Inflatable kayaks made of coated fabrics are versatile and comfortable, but not as fast as hard shells.

Which Should You Choose

A lot hinges on your intended use for the kayak and your personal preferences. In general, a sit-inside kayak is well-suited for camping trips and recreational paddling, while sit-on-top kayaks excel in activities like scuba diving, fishing, and surfing. Consider factors such as water temperature, desired speed, and whether you’ll be navigating sheltered or open waters like rivers, lakes, or coastlines. Ultimately, the decision rests with you, as there are anglers who favor sit-inside kayaks and camping enthusiasts who lean towards sit-on-top options.
