When two boats share the same hull type — in this case both the ThunderJet Bulldog 2009 and the ThunderJet Denali 2012 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?

On paper these two are close siblings in the size department — ThunderJet Bulldog 2009 at 17,0 ft versus ThunderJet Denali 2012 at 18,0 ft. At 25 lbs and 19 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The ThunderJet Bulldog 2009 carries a rated maximum of 2 hp. Engine data for the ThunderJet Denali 2012 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the ThunderJet Denali 2012 carries 48 gallons versus 32 gallons in the ThunderJet Bulldog 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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.
