This certificate can be used by one person for two hours or two people for one hour each either on kayaks or paddleboards.  
The kayaks or paddleboards are available at the SeaTrek Kayak and Standup Paddleboard Center location at the Army Corps Bay Model in Sausalito, California.  Reservations are suggested. 

There is no faster way to transform your world than to jump on a kayak or paddleboard  and take a few paddle strokes. For many, the best place to do that is out of Sausalito at Sea Trek, on the calm waters of Richardson Bay. 

You will love the therapy of paddling on the Bay.  Feel free to upgrade to additional time.  You are going to wish you had!
