Detailed Evaluation & Buyer Recommendation
ThunderJet Alexis - 20 ft. 2008 vs ThunderJet Denali 2013: A Close Look at Two Modified-V Boats
Both the ThunderJet Alexis - 20 ft. 2008 and the ThunderJet Denali 2013 are modified-V designs, both built in aluminium, so 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 - 20 ft. 2008 carries a rated maximum of 425 hp. Engine data for the ThunderJet Denali 2013 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads - 50 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 - 20 ft. 2008 is rated for 8 passengers, while the ThunderJet Denali 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 - 20 ft. 2008 could be the deciding factor.
Bottom line: Choose the ThunderJet Alexis - 20 ft. 2008 if your priority is putting more people on the water - it handles 8 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Denali 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.
