ThunderJet Alexis Outboard - 20 ft. 2008 vs ThunderJet Denali 2013 — Which Modified Vee Fits Your Needs?

When two boats share the same hull type — in this case both the ThunderJet Alexis Outboard - 20 ft. 2008 and the ThunderJet Denali 2013 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 Outboard - 20 ft. 2008 is rated for 6 passengers, while the ThunderJet Denali 2013 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 Outboard - 20 ft. 2008 could be the deciding factor.

Bottom line: Choose the ThunderJet Alexis Outboard - 20 ft. 2008 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably.
