I was thinking the upper and lower LagunaThere are loads of good boats out there. You really need to define what you mean run 40 miles and it might be choppy. Are you talking 40 miles through the marsh with some open water or are you talking 40 miles offshore. If its the later then the answer to your question is nothing. If its the former then I'd look hard at an East Cape Evo. X will be a little skinnier or the V will be a little better in a chop.
Passion and good poling skills plus athletic skiff pushing friends with the same fishing days are required in the Laguna Madre. Does not matter which skiff without those prerequisites, unless you don't mind limited launch days. But what the hell, follow your dreams!Yeah it's got to be a good poling skiff.
