The manufacturer of Kayak Spray Skirt tells you that standard closed deck marine kayaks rely on waterproof skirts to keep the watertight and close the hatch. Kayak Spray Skirt is made of nylon or neoprene material, which is worn around your waist; it has an important function of sealing the cockpit. Open kayaks do not need Kayak Spray Skirt because there is a recess on the deck that allows athletes to sit in it; it is kept impermeable by closed hatches.

 The main advantage of an impervious kayak is that it will not be submerged in the ocean, because assuming you use Kayak Spray Skirt to keep it closed, then water cannot enter the cabin. Without these characteristics, the kayak is no longer safe once it leaves the calm waters. Kayak Spray Skirt should fit well with the cabin and be tightly integrated to ensure that it will not loosen in the waves or when the boat rolls over.
It is not dangerous to be trapped in the cockpit, because of course you will learn how to loosen the Kayak Spray Skirt before you row out. The real danger is wearing a loose Kayak Spray Skirt, at the worst moment, it will make you suddenly leave the kayak. I once saw a friend set sail through three separate waves on a surf belt. He rushed through the first two relatively small waves smoothly, but as he approached the largest one, a wave rushed towards him and washed away his cheap nylon Kayak Spray Skirt. The kayak immediately filled with water, and he started swimming. If there were no strong offshore currents that would continue to bring him back into the sea, this would not be a big problem. When he finally landed successfully with the help of others, he was cold and exhausted. The next day, he bought a high-quality neoprene Kayak Spray Skirt.
