Here's what other sites are saying:
The Zoik SD rafts (Suspended Deck) are a unique combination of cataraft and self bailing raft. You get all the features of both in one boat! The Zoik SD's have the speed, maneuverability, and surfing performance of a cataraft, while at the same time providing the comfort, convenience, loading capacity, and splash protection of a raft. The 15' SD is constructed with huge 26" main tubes, diminishing to 16" at the bow and stern. It has a heavy duty, super tough, 4000 denier floor, suspended 13" up from the bottom of the tubes in the middle of the raft.
