Yes, the StraitEdge inflatable kayaks can be set up as self-bailing or standard (non-bailing). This allows the paddler to set the kayak to their desired paddling conditions. If you plan to get wet in the waves (ocean or river) then we suggest opening the ports on the floor so the kayak is self-bailing. Water that comes in will drain out through the bottom. On the other hand, if you planning to go out for a paddle on flat water and don’t plan to take on waves then close the ports and you have a standard floor kayak.
