Most kayak manufacturers use little plastic eyes to secure deck lines and hold-down bungee cord. The problem with these is that they become painful bumps when you practice wet re-entries, gear snags them, and they're ugly.
Some English kayaks use fancy recessed fittings, which are heavy and hold water. A better method is to use a loop of flat nylon or polypropylene webbing attached with a screw and finish washer. Just run your line or bungee through the loop.
