Sally seaweed

While sailing the Flonian seas you found a plus size but bonny looking lady covered in seaweed floating on some debris. You pull her on board and find out she called Sally and is part Marid (a fay of the sea). She has become a vital part of your crew. Her powers can calm storms, turn salt water into drinking water, and able to talk to sea creatures and monsters. Her hair is always wet, her clothes are made of seaweed, she stands at 5’9 and broad body. Her legs are chunky but smooth and always walks bare foot. Her heavy torso bounce when happy or trying to convince you to see her way (it's a very effective tactic with your crew).
