I don't have have any experience on an East Cape or much poling skiff experience, but I did own a RFL18 for a few years. Three people would work on the boat if the middle guy is standing on the console. It'll run plenty skinny with the tunnel and all, but it'll run shallower than it will float. It doesn't have much use for poling, it's a big flat boat. I'm sure the East Cape would handle chop better than the RFL. I would typically fish shallower water with the trolling motor down, so you're going to need 18" of water do all that. It'll draft somewhat shallow, but will need a trolling motor to move around. The East Cape will probably pole and fish shallower in my opinion. I had a short push pole just to push myself out of very shallow water, hopefully before the wind blasted it into a shoreline.
