Abstract: Side protectors for a water craft include a base which may be affixed to the hull of the craft and into which fits an inflatable bladder. The protectors are modularized and a plurality of the protectors may be affixed to the craft along either horizontal rows or individual protectors may be vertically orientated, depending on the anticipated need for protection. A snap lock type connection, including mating extensions and recesses in a chamber closed at one end, is provided for affixing the bladder edges to the base holder. A space is left between the legs of bladder connector so that when high pressure air is added to cause inflation of the bladder, the same air also creates additional pressure maintaining the bladder coupled to the base. An air compressor and operators panel are provided which permits any of the various bladders to be inflated depending on the particular need at the particular time.
