Umiak type of boat. In the Eastern Arctic, where the umiak was rarely used for hunting, it was used mainly as summer transport for women and children, while men travelled by kayak, and thus was known as a "woman's boat". Umiak The umiak, umialak, umiaq, umiac, oomiac, oomiak, ongiuk, or anyak is a type of open skin boat used by both Yupik and Inuit, and was originally found in all coastal areas from Siberia to Greenland. First arising in Thule times, it has traditionally been used in summer to move people and possessions to seasonal hunting grounds and for hunting whales
Kayak kayaks, designed for open water and rough conditions, are generally narrower at and have more secondary stability than recreational kayaks, which are wider , have a flatter hull shape, and more primary stability. The body of the paddler must also be taken into account. A paddler with a low center of gravity will find all boats more stable; for a paddler with a high center of gravity, all boats will feel tippier. On average, women and children have a lower COG than men. Unisex kayaks are built for men. A paddler with narrow shoulders will also want a narrower kayak.
