The baidarka (small skin boat) was a small boat covered in sea lion skin. It was developed and used for hunting because of its sturdiness and maneuverability. The Aleut baidarka resembles that of a Yup'ik kayak, but it is hydrodynamically sleeker and faster. They made the baidarka for one or two persons only. The deck was made with a sturdy chamber, the sides of the craft were nearly vertical and the bottom was rounded. Most one-man baidarkas were about long and wide, whereas a two-man was on average about long and wide. It was from the baidarka that Aleut men would stand on the water to hunt from the sea.
