ThunderJet Bull Dog 20 ft. 2012 vs ThunderJet Denali 2011 — Which Modified Vee Fits Your Needs?

When two boats share the same hull type — in this case both the ThunderJet Bull Dog 20 ft. 2012 and the ThunderJet Denali 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 Bull Dog 20 ft. 2012 carries a rated maximum of 320 hp. Engine data for the ThunderJet Denali 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 48 gal and 48 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The ThunderJet Bull Dog 20 ft. 2012 is rated for 6 passengers, while the ThunderJet Denali 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Bull Dog 20 ft. 2012 could be the deciding factor.

Bottom line: Choose the ThunderJet Bull Dog 20 ft. 2012 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. The ThunderJet Denali 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
