WhatsSup operates kayak, canoe, and paddleboard rentals from three locations: Bothell Landing Park on the Sammamish River in Bothell, Log Boom Park on Lake Washington's north shore in Kenmore, and Wilmot Gateway Park in Woodinville. Single and double kayak rentals accommodate adults and toddlers up to five years old, with sit-on-top and sit-in options. Canoes are available at the Bothell location. All rentals include paddles, personal floatation devices, and basic instruction. WhatsSup also offers 60-minute paddleboard lessons for ages 13 and up in small groups of one to five students, covering stance, paddling techniques, turning, and safety. Renters must be 18 or older; minors require a parent present. The business also offers combo adventures pairing kayaking or SUP with beach cruiser bike rentals, and operates Kenmore Kayak Storage across from the Sammamish River access.
