Rick,
I have had the opportunity to hunt out of several Devlin boats, Snow Goose, Black Brant 2 and 3, Poleboat. In addition I have been seen several in operation, Scaup 16, Cackler, Mallard, Blue Bill, Broadbill, and Black Brant 1. I have built a Black Brant 3 and a Poleboat. In my mind, for the hunting I do, from marshes along the Mississippi to open water of Green Bay, I think the Black Brant 3 is the best of the bunch with the Snow Goose a close second. The BB3 is extremely stable, low profile, and can handle waves up to 4 ft. (not that I want to do 'that' again). Put a dodger on the front of the cockpit if you want. I currently have a 35 hp on mine but have seen motors of 25 hp push them along with one person. Personally I would not go less than a 30 hp.
