Hi Dechantae, At this point, 5-30-2016, the only differences are basically the look, shape of splash area (more efficient on Blaster), and the Blaster includes an inside return path, so kids don't exit the inflatable to climb the slide. This keeps the splash area cleaner - less grass, mud and debris. Originally, the Blaster included some additional durability and safety features that were later added to the Pirate Bay as well. Sincerely, Blast Zone Support
