To truly give every cadet the best experience possible in the Sea Cadet program, every Sea Cadet unit operates at an optimal total number of cadets. This is based upon, among other things, the available physical space at the unit, the number and experience of the supporting adult staff, and the space limits for much of the hands-on activities in the program. Prior to each of our three onboards each year, we assess the available openings for new cadets based upon our current capacity.  For any number of reasons, cadets may leave the program, opening up slots in the unit. In addition to these available slots, we reserve and prioritize the children of activity duty Navy and Coast Guard families stationed at NAS Jacksonville, transfers from other units (particularly those of activity duty military), and proximity to the unit offices. Unfortunately, we do not know until prior to our next onboard what that availability will be.  If our units are at capacity, we will refer you to our sister unit located at Naval Station Mayport first, if they have openings available. The Mayport program is a distinctive active base-located Sea Cadet unit similar to FD Roosevelt Squadron.
