ThunderJet Alexis 2009 vs ThunderJet Denali 2012 — Which Modified Vee Fits Your Needs?

When two boats share the same hull type — in this case both the ThunderJet Alexis 2009 and the ThunderJet Denali 2012 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 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 Denali 2012 carries 48 gallons versus 5 gallons in the ThunderJet Alexis 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The ThunderJet Denali 2012 at 18,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Alexis 2009 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
