When two boats share the same hull type — in this case both the ThunderJet Alexis Offshore 2012 and the ThunderJet TJ Offshore 26 ft. 2013 are deep vee designs with aluminum construction — 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 ThunderJet TJ Offshore 26 ft. 2013 measures 26,0 feet overall (2013), giving it roughly 4,0 additional feet of deck space compared to the ThunderJet Alexis Offshore 2012 at 22,0 feet (2012). At 31 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 50-hp advantage over the ThunderJet Alexis Offshore 2012's 300-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 Alexis Offshore 2012 carries 48 gallons versus 16 gallons in the ThunderJet TJ Offshore 26 ft. 2013. 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 Offshore 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.
