Harris Flotebote Classic 240 I/O 2006 vs Harris Flotebote Grand Mariner 250 2012 — Same Brand, Different Boat

The Harris Flotebote Classic 240 I/O 2006 vs Harris Flotebote Grand Mariner 250 2012 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Harris Flotebote Classic 240 I/O 2006 at 24,0 ft versus Harris Flotebote Grand Mariner 250 2012 at 26,7 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner 250 2012 tips the scales at 3 546 lbs — 3 512 lbs less than the Harris Flotebote Classic 240 I/O 2006 at 34 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 225 hp, the Harris Flotebote Classic 240 I/O 2006 has a 223-hp advantage over the Harris Flotebote Grand Mariner 250 2012's 2-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Classic 240 I/O 2006 is rated for 17 passengers, while the Harris Flotebote Grand Mariner 250 2012 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Classic 240 I/O 2006 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Classic 240 I/O 2006 if your priority is putting more people on the water — it handles 17 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Grand Mariner 250 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

Harris Flotebote Classic 240 I/O 2006 vs Harris Flotebote Grand Mariner 250 2012 — Common Questions

Which is the larger boat — the Harris Flotebote Classic 240 I/O 2006 or the Harris Flotebote Grand Mariner 250 2012?
The Harris Flotebote Grand Mariner 250 2012 is the longer of the two at 26,7 feet overall. The Harris Flotebote Classic 240 I/O 2006 comes in at 24,0 feet, making it roughly 2,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Classic 240 I/O 2006 or the Harris Flotebote Grand Mariner 250 2012?
For trailering, the Harris Flotebote Classic 240 I/O 2006 has the edge at 34 lbs dry weight versus 3 546 lbs for the Harris Flotebote Grand Mariner 250 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 Harris Flotebote Classic 240 I/O 2006 is rated to a maximum of 225 hp, giving it the larger power ceiling. The Harris Flotebote Grand Mariner 250 2012 tops out at 2 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 Harris Flotebote Classic 240 I/O 2006 is Coast Guard rated for 17 passengers, while the Harris Flotebote Grand Mariner 250 2012 is certified for 2. 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 Harris Flotebote Classic 240 I/O 2006 and Harris Flotebote Grand Mariner 250 2012 share an 8 ft. 6 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 Harris Flotebote Classic 240 I/O 2006 and Harris Flotebote Grand Mariner 250 2012 from the same manufacturer?
Yes — both the Harris Flotebote Classic 240 I/O 2006 and the Harris Flotebote Grand Mariner 250 2012 are built by Harris Flotebote. 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.
