Detailed Evaluation & Buyer Recommendation
ThunderJet Bull Dog 20 ft. 2012 vs ThunderJet TJ Offshore 2008 — 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 TJ Offshore 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 ThunderJet Bull Dog 20 ft. 2012 carries a rated maximum of 320 hp. Engine data for the ThunderJet TJ Offshore 2008 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The ThunderJet TJ Offshore 2008 is rated for 8 passengers, while the ThunderJet Bull Dog 20 ft. 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet TJ Offshore 2008 could be the deciding factor.
Bottom line: Choose the ThunderJet TJ Offshore 2008 if your priority is putting more people on the water — it handles 8 passengers and at 28,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Bull Dog 20 ft. 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
