The Harris Flotebote Classic 240 I/O 2005 vs Harris Flotebote Grand Mariner 250 SL 2011 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 2005 at 24,0 ft versus Harris Flotebote Grand Mariner 250 SL 2011 at 25,0 ft.

The Harris Flotebote Grand Mariner 250 SL 2011 is the longer of the two at 25,0 feet overall. The Harris Flotebote Classic 240 I/O 2005 comes in at 24,0 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 Harris Flotebote Classic 240 I/O 2005 or the Harris Flotebote Grand Mariner 250 SL 2011?
For trailering, the Harris Flotebote Classic 240 I/O 2005 has the edge at 34 lbs dry weight versus 322 lbs for the Harris Flotebote Grand Mariner 250 SL 2011. 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.
What is the maximum horsepower rating for these boats?
The Harris Flotebote Classic 240 I/O 2005 has a documented max rating of 225 hp. Engine specifications for the Harris Flotebote Grand Mariner 250 SL 2011 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Harris Flotebote Classic 240 I/O 2005 is Coast Guard rated for 11 passengers, while the Harris Flotebote Grand Mariner 250 SL 2011 is certified for 13. 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 2005 and Harris Flotebote Grand Mariner 250 SL 2011 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 2005 and Harris Flotebote Grand Mariner 250 SL 2011 from the same manufacturer?
Yes — both the Harris Flotebote Classic 240 I/O 2005 and the Harris Flotebote Grand Mariner 250 SL 2011 are built by Harris Flotebote.
