Both the ThunderJet Bull Dog 20 ft. 2012 and the ThunderJet Bull Dog 20 ft. 2013 are modified-V designs, both built in aluminium, so 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 Bull Dog 20 ft. 2012 at 20,0 ft versus ThunderJet Bull Dog 20 ft. 2013 at 20,0 ft. At 3 300 lbs and 3 300 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.

Both boats share a closely matched power ceiling - 320 hp for the ThunderJet Bull Dog 20 ft. 2012 and 320 hp for the ThunderJet Bull Dog 20 ft. 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads - 48 gal and 48 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.
