Matching a modified vee ThunderJet Alexis 2012 against a deep vee ThunderJet TJ Offshore 26 ft. 2013 means you're likely deciding between two genuinely 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 26 ft. 2013 measures 26,0 feet overall (2013), giving it roughly 5,0 additional feet of deck space compared to the ThunderJet Alexis 2012 at 21,0 feet (2012). At 32 lbs and 48 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 350 hp, the ThunderJet TJ Offshore 26 ft. 2013 has a 318-hp advantage over the ThunderJet Alexis 2012's 32-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 26 ft. 2013 carries 16 gallons versus 5 gallons in the ThunderJet Alexis 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 26 ft. 2013 is rated for 7 passengers, while the ThunderJet Alexis 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet TJ Offshore 26 ft. 2013 could be the deciding factor.
Bottom line: Choose the ThunderJet TJ Offshore 26 ft. 2013 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 Alexis 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
