The Harmony® Vinyl Short Float Bag Set includes two stern and two bow bags to accommodate center walls. The tie-ins are isolated from the air holding cell so that a tear out will be limited to the anchor. A twist valve on the inflation hose ensures a positive seal, while a high capacity dump valve offers easy deflation. Temperature-regulating colored material reduces burst risk on hot, sunny days.
