If you want a kayak suitable for paddling on both lakes and in the archipelago, it should be a middle ground between a classic sea kayak and a lake kayak. Such a middle ground is about 5 m long and has a cockpit with generous height. If you are only going to paddle in calm water, you can have a slightly shorter kayak with a lower cockpit, but a longer kayak works well too. If you are only going to paddle in the windy parts of the archipelago, it may be a good idea to have a longer kayak (at least 5 m) for increased speed and tracking stability. If you are only going on shorter day trips, the kayak's storage compartments do not need to be a significant factor in your choice. If you want to go on slightly longer trips, with 1-2 days of overnight camping, it is good to ensure the kayak's hatches can accommodate food, extra clothes, a tent, etc., that you want to bring along. If you are going on really long trips, you should make sure your kayak has substantial storage compartments with large volume. With larger storage and a longer kayak, you have to compromise on the kayak's maneuverability, and you should be aware that the kayak can be unwieldy to handle on land.

The paddler's height, weight, and body size are all factors that come into play when choosing a kayak. For children, a shorter kayak (approx. 3-4 m) is usually best for good maneuverability, while adults can paddle kayaks that are between 4.5-6 m long. A kayak shorter than 4.5 m has poorer tracking stability, which means you lose speed in the water. It is important that the foot pegs, which you use to steer the rudder at the rear of the kayak, are adjustable to the desired length. The seat should be shaped in a way that feels comfortable to sit in. It is also good if the backrest can be adjusted in height and side-to-side while sitting in the kayak.
