The Seaplane Pilots Association (SPA) is a Lakeland, Florida-based American non-profit political organization that advocates for seaplane aviation. The association was founded by David Quam, Robert Murray, Al Lisch and William Hooper in 1972. The founding purpose of the Association was to protect seaplane access to public waters, promote seaplane flying and publish a member Newsletter and Seaplane Base Directory. SPA states that its mission is, “to be the voice of the seaplane community and to represent the interests of seaplane enthusiasts on the federal, state, and local levels. It includes ensuring fairness and equality for seaplanes to share public waterways with all other user groups. Other key elements of our Mission include Safety, Education, and Environmental Stewardship.”
