ThunderJet Denali 2011 vs ThunderJet Denali OB 2010 — A Close Look at Two Modified Vees

When two boats share the same hull type — in this case both the ThunderJet Denali 2011 and the ThunderJet Denali OB 2010 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?

For family outings this is probably the sharpest distinction between the two. The ThunderJet Denali 2011 is rated for 5 passengers, while the ThunderJet Denali OB 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the ThunderJet Denali 2011 could be the deciding factor.

Bottom line: Choose the ThunderJet Denali 2011 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The ThunderJet Denali OB 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

ThunderJet Denali 2011 vs ThunderJet Denali OB 2010 — Common Questions

Which is the larger boat — the ThunderJet Denali 2011 or the ThunderJet Denali OB 2010?
The ThunderJet Denali 2011 is the longer of the two at 18,0 feet overall. The ThunderJet Denali OB 2010 comes in at 16,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
How many people can each boat hold?
The ThunderJet Denali 2011 is Coast Guard rated for 5 passengers, while the ThunderJet Denali OB 2010 is certified for 4. 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 Denali OB 2010 measures 84" wide, compared to 9" for the ThunderJet Denali 2011. 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 Denali 2011 or the ThunderJet Denali OB 2010?
The ThunderJet Denali 2011 has the bigger tank at 48 gallons, versus 28 gallons on the ThunderJet Denali OB 2010. That 20-gallon difference translates to roughly 60–100 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the ThunderJet Denali 2011 and ThunderJet Denali OB 2010 from the same manufacturer?
Yes — both the ThunderJet Denali 2011 and the ThunderJet Denali OB 2010 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.
