ThunderJet Alexis Offshore 2013 vs ThunderJet Bull Dog 20 ft. 2012 — Same Brand, Different Boat

Matching a deep vee ThunderJet Alexis Offshore 2013 against a modified vee ThunderJet Bull Dog 20 ft. 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The ThunderJet Alexis Offshore 2013 measures 22,0 feet overall (2013), giving it roughly 20,0 additional feet of deck space compared to the ThunderJet Bull Dog 20 ft. 2012 at 2,0 feet (2012). At 31 lbs and 33 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 — 300 hp for the ThunderJet Alexis Offshore 2013 and 320 hp for the ThunderJet Bull Dog 20 ft. 2012. 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.

Bottom line: The ThunderJet Alexis Offshore 2013 at 22,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The ThunderJet Bull Dog 20 ft. 2012 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

ThunderJet Alexis Offshore 2013 vs ThunderJet Bull Dog 20 ft. 2012 — Common Questions

Which is the larger boat — the ThunderJet Alexis Offshore 2013 or the ThunderJet Bull Dog 20 ft. 2012?
The ThunderJet Alexis Offshore 2013 is the longer of the two at 22,0 feet overall. The ThunderJet Bull Dog 20 ft. 2012 comes in at 2,0 feet, making it roughly 20,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the ThunderJet Alexis Offshore 2013 or the ThunderJet Bull Dog 20 ft. 2012?
For trailering, the ThunderJet Alexis Offshore 2013 has the edge at 31 lbs dry weight versus 33 lbs for the ThunderJet Bull Dog 20 ft. 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The ThunderJet Bull Dog 20 ft. 2012 is rated to a maximum of 320 hp, giving it the larger power ceiling. The ThunderJet Alexis Offshore 2013 tops out at 300 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The ThunderJet Alexis Offshore 2013 is Coast Guard rated for 6 passengers, while the ThunderJet Bull Dog 20 ft. 2012 is certified for 6. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The ThunderJet Alexis Offshore 2013 measures 102" wide, compared to 96" for the ThunderJet Bull Dog 20 ft. 2012. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

Both boats carry similar fuel loads — 48 gallons and 48 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.

Yes — both the ThunderJet Alexis Offshore 2013 and the ThunderJet Bull Dog 20 ft. 2012 are built by ThunderJet. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
