THE SEAT ON the forward portion of a walkaround cuddy represents wasted space, in my opinion. It’s comfy on a harbor cruise, but too bouncy while underway. So I swapped this seat on my boat for a cooler rack to carry extra ice. Each boat requires special engineering, but in my case, I removed the seat cushion, then cut a platform from a 24-by-27-inch sheet of ¾-inch Taco Marine plastic lumber (about $145). The platform rests on four through-bolted King Starboard legs made from 1-inch material. An Attwood coolermounting kit (about $15) prevents sliding, and a Yeti cooler tie-down strap kit (about $49) dogs it down. Now the cooler is out from underfoot but easy to access.
