When two boats share the same hull type — in this case both the ThunderJet Denali 2009 and the ThunderJet Luxor Outboard Offshore - 20 ft. 2008 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 power gap is worth calling out. Rated to 500 hp, the ThunderJet Luxor Outboard Offshore - 20 ft. 2008 has a 498-hp advantage over the ThunderJet Denali 2009's 2-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
