It's a 2 seater, it's an old bass tracker tadpole model, belive it or not it's recommended for 3 people, but it's more comfy with 2, it's a heavy boat, that I just put in the back of my pick up truck. I have never flipped it, but my father who's about 250# gave it the ultimate test a few years ago by missing the seat and falling inside the boat! Nobody went over board

I use it as my primary largemouth/small water boat.
I have a fishin buddy depth finder, it's not a good one like yours GS but when I white perch fish in the CT River Coves it marks fish that are directly under my boat. Obviously the more water the better the transducer can have a better angle of finding some fish. I use it primarily for water temp, and looking for humps and bumps. How deep is it out in the Channel GS, about 20-30ft.?
Is that boat launch capable of launching 2 boats at once? I don't have a tailer so I don't like to hold up all the big boy bass/boats.
By myself it takes about 10 minutes to launch. I might just be better off seeing what the boat traffic looks like up there on a Saturday before I pull it out. We'll see what happens when I get up tommorrow. Or who knows maybe I will get up early and just head on out there @ 5 oclock and beat the boat launch rush, I will play it by ear I guess.
Oh by the way I live in CT, just on the other side of the state.
