The ThunderJet NE Envoy 2012 is a modified-V design and the ThunderJet TJ Offshore 2012 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The ThunderJet TJ Offshore 2012 measures 26,0 feet overall (2012), giving it roughly 7,0 additional feet of deck space compared to the ThunderJet NE Envoy 2012 at 19,0 feet (2012). Weight tells a clearer story for trailering families: the ThunderJet TJ Offshore 2012 tips the scales at 4 800 lbs - 2 400 lbs less than the ThunderJet NE Envoy 2012 at 2 400 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.
The power gap is worth calling out. Rated to 350 hp, the ThunderJet TJ Offshore 2012 has a 30-hp advantage over the ThunderJet NE Envoy 2012's 320-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the ThunderJet TJ Offshore 2012 carries 160 gallons versus 48 gallons in the ThunderJet NE Envoy 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The ThunderJet TJ Offshore 2012 is rated for 7 passengers, while the ThunderJet NE Envoy 2012 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet TJ Offshore 2012 could be the deciding factor.
Bottom line: Choose the ThunderJet TJ Offshore 2012 if your priority is putting more people on the water - it handles 7 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The ThunderJet NE Envoy 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
