ThunderJet Alexis 2013 vs ThunderJet Alexis Offshore 2013 — Same Brand, Different Boat

Matching a modified vee ThunderJet Alexis 2013 against a deep vee ThunderJet Alexis Offshore 2013 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.

On paper these two are close siblings in the size department — ThunderJet Alexis 2013 at 21,0 ft versus ThunderJet Alexis Offshore 2013 at 22,0 ft. At 32 lbs and 31 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 Alexis 2013 and 300 hp for the ThunderJet Alexis Offshore 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. Fuel capacity breaks the other way: the ThunderJet Alexis Offshore 2013 carries 48 gallons versus 5 gallons in the ThunderJet Alexis 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

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: Performance buyers should lean toward the ThunderJet Alexis 2013 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the ThunderJet Alexis Offshore 2013 with its 300-hp rating is the more economical daily driver.

ThunderJet Alexis 2013 vs ThunderJet Alexis Offshore 2013 — Common Questions

Which is the larger boat — the ThunderJet Alexis 2013 or the ThunderJet Alexis Offshore 2013?
The ThunderJet Alexis Offshore 2013 is the longer of the two at 22,0 feet overall. The ThunderJet Alexis 2013 comes in at 21,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the ThunderJet Alexis 2013 or the ThunderJet Alexis Offshore 2013?
For trailering, the ThunderJet Alexis Offshore 2013 has the edge at 31 lbs dry weight versus 32 lbs for the ThunderJet Alexis 2013. 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 Alexis 2013 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 2013 is Coast Guard rated for 6 passengers, while the ThunderJet Alexis Offshore 2013 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 Alexis 2013. 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.
Which boat has the larger fuel tank — the ThunderJet Alexis 2013 or the ThunderJet Alexis Offshore 2013?
The ThunderJet Alexis Offshore 2013 has the bigger tank at 48 gallons, versus 5 gallons on the ThunderJet Alexis 2013. That 43-gallon difference translates to roughly 129–215 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the ThunderJet Alexis 2013 and ThunderJet Alexis Offshore 2013 from the same manufacturer?
Yes — both the ThunderJet Alexis 2013 and the ThunderJet Alexis Offshore 2013 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.
