As previously noted, the Tempest has a set of holes in the seat pan, for attachment. I recently got a Wavesport WW boat, sister brand to Wilderness Systems. Similar seat pan. Only difference in attachment is that the seat pan is slotted, and, instead of individual nuts, there's a single, threaded backer plate to accomodate both machine screws. So, it's easy to adjust, with just a Phillips screwdriver. Loosen --> slide seat --> tighten. So, they _could_ make it that easy on the sea kayaks, but just don't see it as necessary.
