I must say i like the looks of boice and I have been in a few of them. They run like flipping race boats corner well but they don't fish for S***. Round bottom when you are anchored likes to wander same when back trolling or boondogging and hard as hell to keep straight when trolling. you alwayas have to have a hand on the wheel when driving the boat always wants to turn! Remeber the starters of jet boating the New Zelanders use to run radias bottoms and found out all the defects and went back to more of a std design. My .02
This is a hard choice. These are the only two sleds I would own and I currently have a 19ft NR Sportjet. Fantastic boat. Does everything very well. The Boice is sexier in finish but I agree that the radius hull, while turning will slide less, will not track as well trolling. Also their new Euro type hull puts a long angle down to the swim platform, making kicker placement and rod fighting clearance almost as bad a stretch as twin OB's on a bracket. One thing I love about Boice is their V-6 Vortec short coupling putting reliable efficient 230hp in a box not any bigger than the Merc Optimax doghouse. Also check out the Marathon Marine line that Boice picked up. Have fun.
I would rather have a boat that fishes well, than a "pretty" go fast boat. As far as how all of the top jet boats are built, they are all built nice. Just some have more creature comforts than others. Hull design, is a little different for each manufature too. As far as the hulls, almost ALL of the boats are built using 5086 bottoms. Some may have 5052 material for sides but that is about the only diference. I have been to the factories and looked at most of the jet boats built in the Northwest. As a certified weld inspector, I think I am more than qualified to look at how aluminum boats are built.
I've never driven a Boice, but it would truly be amazing if it corners better than the North River. Mine corners like it's on rails. More important, in the two years I've owned it, it has consistently proved itself as a fishing machine. No slam against the Boice.
North River builds a top notch fishing boat of which several models to choose from. Boice builds a nice race boat that they are trying to sell to fisherman. If you wanna go racing, look at boice, if you want to fish then make the obvious choice.
