Problem with that is there may not be a place to dock other than the "active docks". I launched a lot at the Genesee river and there is no non active area. They are marked thought for launch and retrieve.
I have a 18 ft boat now but owed a 22ft and a 21ft boat in the past. Always ran downriggers off starting battery and never had a problem in about 35 years. Now I have 2 cannons but in the past ran 4 downriggers.
I use this for bass fishing. Really nice to be able to move a good fish away from trouble like a dock or tree limbs using the pedals. When I can't use the pedals because of weeds I find it's a pain to hold the paddle in one hand and the rod in the other.
I owned a Crestliner 1750 for 11 yrs and now own a Alumacraft 1850. No complaints on either. All the boats mentioned are good. I'd just go with the best deal you can get. I'd also consider the dealer reputation.
