Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis 2012 vs ThunderJet Denali OB 2010 — Which Modified Vee Fits Your Needs?
When two boats share the same hull type — in this case both the ThunderJet Alexis 2012 and the ThunderJet Denali OB 2010 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 ThunderJet Alexis 2012 carries a rated maximum of 32 hp. Engine data for the ThunderJet Denali OB 2010 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the ThunderJet Denali OB 2010 carries 28 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 Alexis 2012 is rated for 6 passengers, while the ThunderJet Denali OB 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Alexis 2012 could be the deciding factor.
Bottom line: Choose the ThunderJet Alexis 2012 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 Denali OB 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
