The sport utility trailer, or SURV, the towable RV that allows campers to haul their all-terrain vehicles (ATVs), motorcycles, personal watercraft (PWCs) or snowmobiles to their destination has become popular in the last few years.

However, at least one environmentalist group, the San Francisco-based Bluewater Network, has expended its effort to get the National Park Service (NPS) to restrict, and in some cases ban, the use of the types of vehicles that could be hauled in an SURV.

On Thursday (Aug. 31), Bluewater filed a lawsuit asking a federal court to order the NPS to ban PWCs from 21 national lake and seashores, and national recreation areas administered by the NPS.

The Bluewater has also asked the NPS to develop rules to restrict the use of ATVs to the “park system’s high standard gravel or paved surfaces.”

Additionally, the NPS agreed in April, at the urging of Bluewater, to begin developing rules to prohibit “recreational snowmobiling” on the properties over which it has jurisdiction.

The American Watercraft Association (AWA), which represents PWC owners, said it believes Bluewater’s lawsuit is frivolous.

“While the AWA seeks reasonable regulations for PWCs and other motorized activities, the Bluewater Network seeks to ban all motorized activities including motorcycles, ATVs and snowmobiles,” according to the AWA.
