Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis 2013 vs ThunderJet Alexis Classic - 21 ft. 2008 — A Close Look at Two Modified Vees
When two boats share the same hull type — in this case both the ThunderJet Alexis 2013 and the ThunderJet Alexis Classic - 21 ft. 2008 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?
The power gap is worth calling out. Rated to 500 hp, the ThunderJet Alexis Classic - 21 ft. 2008 has a 180-hp advantage over the ThunderJet Alexis 2013's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 8 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis Classic - 21 ft. 2008 is rated for 8 passengers, while the ThunderJet Alexis 2013 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Alexis Classic - 21 ft. 2008 could be the deciding factor.
Bottom line: Choose the ThunderJet Alexis Classic - 21 ft. 2008 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Alexis 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
