When two boats share the same hull type — in this case both the ThunderJet Aladdin 2010 and the ThunderJet Alexis 2011 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 2011 tops out at 425 hp. Engine specs for the ThunderJet Aladdin 2010 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the ThunderJet Alexis 2011 carries 48 gallons versus 32 gallons in the ThunderJet Aladdin 2010. 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 2011 is rated for 6 passengers, while the ThunderJet Aladdin 2010 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 2011 could be the deciding factor.
