ThunderJet Maxim Classic 2009 vs ThunderJet TJ Offshore 2008: Which Modified-V Boat Fits Your Needs?

Both the ThunderJet Maxim Classic 2009 and the ThunderJet TJ Offshore 2008 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?

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 Maxim Classic 2009 caps at 7. 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 Maxim Classic 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

ThunderJet Maxim Classic 2009 vs ThunderJet TJ Offshore 2008 - Common Questions

Which is the larger boat - the ThunderJet Maxim Classic 2009 or the ThunderJet TJ Offshore 2008?
The ThunderJet TJ Offshore 2008 is the longer of the two at 28,0 feet overall. The ThunderJet Maxim Classic 2009 comes in at 23,0 feet, making it roughly 5,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
How many people can each boat hold?
The ThunderJet Maxim Classic 2009 is Coast Guard rated for 7 passengers, while the ThunderJet TJ Offshore 2008 is certified for 8. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the ThunderJet Maxim Classic 2009 and ThunderJet TJ Offshore 2008 share an 108 in. beam - meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Are the ThunderJet Maxim Classic 2009 and ThunderJet TJ Offshore 2008 from the same manufacturer?
Yes - both the ThunderJet Maxim Classic 2009 and the ThunderJet TJ Offshore 2008 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.
