When two boats share the same hull type — in this case both the ThunderJet Alexis OB 2009 and the ThunderJet Denali OB 2010 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?

For family outings this is probably the sharpest distinction between the two. The ThunderJet Alexis OB 2009 is rated for 6 passengers, while the ThunderJet Denali OB 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Alexis OB 2009 could be the deciding factor.
