I am about to pull the trigger on an inflatable personal watercraft (either a Scadden Outlaw Renegade or a WaterMaster) and I need some guidance on pumps. I have no experience with inflatable watercraft yet and I am not sure exactly what I need in the pump area. Should I get one of the K-Pumps? If so, what size? What about one of the electric pumps that you hook up to you car battery? Are they worth it or can you inflate the boat quickly enough with a hand or foot pump? Any guidance is greatly appreciated. Thanks!
