When two boats share the same hull type — in this case both the ThunderJet Alexis OB 2010 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?

Size is the most obvious dividing line here. The ThunderJet Denali 2012 measures 18,0 feet overall (2012), giving it roughly 16,0 additional feet of deck space compared to the ThunderJet Alexis OB 2010 at 2,0 feet (2010). At 18 lbs and 19 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis OB 2010 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 2010 could be the deciding factor.
