Bret, I should fully disclose that Robinson, Morton and I do earn a commission if you decide to order Snowgoose plans from Devlin... ; )
Fortunately Dave and I have a lot of experience together in the same conditions... our conditions are very similar to what you experience in NJ... I have hunted Tuckerton (out to the old cannery), etc... and the Delaware River... both remind me of RI's bay.
Both boats perform similarly, yet their hull designs are different. Take a look at the Devlin page and study the hulls... Dave's Cackler is almost 2 feet shorter than mine, but both boats handle similarly... the two differences are speed (his a 30, mine a 40hp), mine is a smidge faster, but I ascribe that to Dave eating too many donuts and having more ducks on the floor, Dave is a much better shot than I...
2) my boat pops out of the water faster, but that is due to the hull design, the boats front end gets up and out quickly. Dave did not build to the original Cacler design, he moved his well back, which I thought was smart as he purchased way more usable space... Dave seems to go out front more often in rough weather because I'm a woos, ditto for shallow water running in rocky areas...
Seriously, one cool feature of the Snow Goose, and this happened just the other day, in really shallow water, the hull scrapes bottom/rock B4 the engine will... it gives one a split second warning to throw the engine in neutral or kick the motor up another degree...
Dave's boat is lighter and therefore slightly easier to load/unload and to maneuver around the weeds... however, if either boat is high and dry, they both are high and dry. Can't drag either like a BBSB.
When underway, your feet placement is right at the pivot point, i.e. when you go into and out of the trough of a 4 footer, you aren't slammed at all, in fact you don't even have to hang on... it's weird...
BTW, the Scaup and Snowgoose have the same hull. The major difference is the height of the freeboard, the Scaup's less with greater hideability. I feel more comfortable with more freeboard where we hunt.
Good luck and ask a million questions, that's the fun of building a duck boat... this site has a lot of experienced great guys. Tod has a Snowgoose, and he has developed some very cool hunting mods you may want to check out.
