A two-section kayak is disclosed where a user can create a gap between a kayak front section and a kayak back section, and use this gap to enter and exit the water. Connecting poles are preferably used to create the gap and retain structural integrity of the kayak when the two sections are separated. A variety of foot stirrups and ladders are contemplated to allow a user to more easily reenter the kayak through he gap. One or more gap alcoves are contemplated to store a stirrup or ladder and to allow the user ready access to swimming, snorkeling and scuba diving accessories while in the gap. A viewing portal, and a hanging seat/platform are contemplated for attachment in the gap, to allow users a more varied kayaking experience. An optional third kayak section is contemplated to add storage space or turn a single into a double kayak.
