Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis OB OS 2011 vs ThunderJet Denali 2012 — Same Brand, Different Boat
Matching a deep vee ThunderJet Alexis OB OS 2011 against a modified vee ThunderJet Denali 2012 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.
The ThunderJet Alexis OB OS 2011 carries a rated maximum of 300 hp. Engine data for the ThunderJet Denali 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 48 gal and 48 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis OB OS 2011 is rated for 6 passengers, while the ThunderJet Denali 2012 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 OB OS 2011 could be the deciding factor.
Bottom line: Choose the ThunderJet Alexis OB OS 2011 if your priority is putting more people on the water — it handles 6 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Denali 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
