ThunderJet Alexis Classic 2009 vs ThunderJet Denali 2012: A Close Look at Two Modified-V Boats

Both the ThunderJet Alexis Classic 2009 and the ThunderJet Denali 2012 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 Classic 2009 carries a rated maximum of 325 hp. Engine data for the ThunderJet Denali 2012 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the ThunderJet Alexis Classic 2009 carries 80 gallons versus 48 gallons in the ThunderJet Denali 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 Classic 2009 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 Classic 2009 could be the deciding factor.

Bottom line: Choose the ThunderJet Alexis Classic 2009 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 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.
