Double, double swim and paddle; muscles burn and teeth rattle — at least, they did for the witches in Quartermaster Harbor last weekend.

Dozens of them took to the water at Jensen Point late Sunday morning for the third annual Vashon Witches’ Paddle.

The all-ages event brings a crowd of islanders out each year to don witchy outfits and take to the water via paddleboards, kayaks and other self-propelled water vehicles.

Operating a paddleboard in the cold fall sun is no easy feat, and at least one witch lost balance and plunged into the bay. But she easily swam back aboard her paddleboard — proving that witches do indeed float.

No spells or incantations were cast, but these witches do use their powers for good.

Proceeds from shirt sales and donations to the event will be split between The DOVE Project and the Donna Donnelly Scholarship Fund, according to event organizers. Last year, the witches raised $200 to split between Vashon Youth and Family Services and the Vashon Senior Center.
