When two boats share the same hull type — in this case both the ThunderJet Alexis 2013 and the ThunderJet Luxor 2013 are modified 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?
On paper these two are close siblings in the size department — ThunderJet Alexis 2013 at 21,0 ft versus ThunderJet Luxor 2013 at 19,0 ft. At 32 lbs and 24 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.
Both boats share a closely matched power ceiling — 320 hp for the ThunderJet Alexis 2013 and 320 hp for the ThunderJet Luxor 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the ThunderJet Luxor 2013 carries 48 gallons versus 5 gallons in the ThunderJet Alexis 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 Alexis 2013 is rated for 6 passengers, while the ThunderJet Luxor 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Alexis 2013 could be the deciding factor.
Bottom line: Choose the ThunderJet Alexis 2013 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Luxor 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
