This past season, I modified my 16' Lund to use for hunting the "big water". It really handles the rough water well, will accomodate up tp 3 hunters comfortably and allows me to go out when smaller craft can't leave the landing. With a 90 h.p. outboard, I can get there pretty quick as well.
Basically I built a framework out of 2x2's and use electrical zip ties to secure grass mats to the framework. I carry a camo burlap tarp to cover the engine. When pushed back into the cattails or cane's this blind really disappears!
