Wappa Paddle Boards is a Canadian manufacturer of eco-friendly bamboo paddle boards. The company is looking to sponsor SUP races and events across Canada and the Western United States.
I’ve been looking forward to the Bay Bridge Paddle (https://paddleguru.com/races/BayBridgePaddle2017). I did it last year. I don’t race – only leisurely paddle paddle – but it was loads of fun. Not sure if this type of event is what you’re looking for or if the organizers are even looking for sponsors. Hope that helps.
