coming from a '93 205 to an x-14, I have no problem at all with storage. I am the only one who still skis, and mine goes under observer seat/port bow. We do have slalom racks on tower, but the kids boards go there. As mentioned before, vests, ropes, cushions, go in the stbd locker, and bumbers, lines, anything else goes under bow seats. We keep towels, cooler, snacks under observer as well, nothing on the floor.
I can see where storage would be an issue coming from a larger boat, but coming from my 205, I couldn't be happier.
