There's only one choice if you're looking to smooth out the decks, and that's the folding version. Again, if it's a question of look, they are worth the energy. From a practical standpoint, however, chocks should be ready the moment they are needed. For anchoring, time is not an issue; for docking or towing, however, the concentration should be on the activity because setup time is often short. Installation is simple. Drill a couple of holes, use sealant to prevent leaking below deck and screw it in.
