non-skid
I've seen the interlocking squares at Costco for substantially lower price,same quality or better than west marine.To keep them from slipping, install a molding strip.If you're having drainage problems in the cockpit, you might consider adding a couple more drain outlets to clear the water faster. My preference would be a quicker draining cockpit over adding another maintenance item.You can find the rubber mats at any restaurant supply house but they aren't designed for outdoor use. I don't recommend them, becuase they are somewhat flat on the bottom preventing the water from draining well which allows the holes to fill with water. Very quickly you will get a lot of "mung" in the holes so your maintenance time will increase. Restaurants pressure wash the mats almost daily, (at least mine did). Another proplem is that they may stain your gel coat, in the same way dark, rubber soled shoes will. Think of you car mechanic walking around in your wet cockpit with his work shoes......
