Smith's makes a model that mounts to your seat pedestals, and has a base with the holders that sets on the deck. I sell em, but don't stock that model. Most good aluminum holders have a base that screws to the deck. Easy to remove, and you can't see the holes when you take them off the boat (If you have carpet). The bases mount low to the deck, and most people leave the bases on their boat, and slide the rod holders off. The bases usually screw down with 3-4 #14 sheet metal screws. Easy to do, very little damage to the deck.
