Both the Nor-Tech 392 Super Fish 2013 and the Nor-Tech 420 Monte Carlo 2013 are deep-V designs, both built in composite, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Nor-Tech 420 Monte Carlo 2013 measures 42,8 feet overall (2013), giving it roughly 3,8 additional feet of deck space compared to the Nor-Tech 392 Super Fish 2013 at 39,0 feet (2013). Weight tells a clearer story for trailering families: the Nor-Tech 392 Super Fish 2013 tips the scales at 13 000 lbs - 1 500 lbs more than the Nor-Tech 420 Monte Carlo 2013 at 11 500 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
For family outings this is probably the sharpest distinction between the two. The Nor-Tech 420 Monte Carlo 2013 is rated for 13 passengers, while the Nor-Tech 392 Super Fish 2013 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Nor-Tech 420 Monte Carlo 2013 could be the deciding factor.
Bottom line: Choose the Nor-Tech 420 Monte Carlo 2013 if your priority is putting more people on the water - it handles 13 passengers and at 42,8 ft it has the deck room to back that rating up comfortably. The Nor-Tech 392 Super Fish 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
