For family outings this is probably the sharpest distinction between the two. The ThunderJet Rio Classic 2008 is rated for 8 passengers, while the ThunderJet Alexis OB Offshore 2010 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Rio Classic 2008 could be the deciding factor.

How many people can each boat hold?
