Harris Flotebote Grand Mariner 230 SEL 2011 vs Harris Flotebote Super Sunliner 240 SSL 2007 — Same Brand, Different Boat

The Harris Flotebote Grand Mariner 230 SEL 2011 vs Harris Flotebote Super Sunliner 240 SSL 2007 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 Grand Mariner 230 SEL 2011 at 23,0 ft versus Harris Flotebote Super Sunliner 240 SSL 2007 at 25,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner 230 SEL 2011 tips the scales at 3 477 lbs — 1 013 lbs more than the Harris Flotebote Super Sunliner 240 SSL 2007 at 2 464 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 300 hp, the Harris Flotebote Grand Mariner 230 SEL 2011 has a 150-hp advantage over the Harris Flotebote Super Sunliner 240 SSL 2007's 150-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 Super Sunliner 240 SSL 2007 is rated for 16 passengers, while the Harris Flotebote Grand Mariner 230 SEL 2011 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Super Sunliner 240 SSL 2007 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Super Sunliner 240 SSL 2007 if your priority is putting more people on the water — it handles 16 passengers and at 25,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Grand Mariner 230 SEL 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.

Harris Flotebote Grand Mariner 230 SEL 2011 vs Harris Flotebote Super Sunliner 240 SSL 2007 — Common Questions

Which is the larger boat — the Harris Flotebote Grand Mariner 230 SEL 2011 or the Harris Flotebote Super Sunliner 240 SSL 2007?
The Harris Flotebote Super Sunliner 240 SSL 2007 is the longer of the two at 25,0 feet overall. The Harris Flotebote Grand Mariner 230 SEL 2011 comes in at 23,0 feet, making it roughly 2,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Grand Mariner 230 SEL 2011 or the Harris Flotebote Super Sunliner 240 SSL 2007?
For trailering, the Harris Flotebote Super Sunliner 240 SSL 2007 has the edge at 2 464 lbs dry weight versus 3 477 lbs for the Harris Flotebote Grand Mariner 230 SEL 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.
Which boat can handle a bigger outboard?
The Harris Flotebote Grand Mariner 230 SEL 2011 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Harris Flotebote Super Sunliner 240 SSL 2007 tops out at 150 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 Grand Mariner 230 SEL 2011 is Coast Guard rated for 14 passengers, while the Harris Flotebote Super Sunliner 240 SSL 2007 is certified for 16. 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 Grand Mariner 230 SEL 2011 and Harris Flotebote Super Sunliner 240 SSL 2007 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 Grand Mariner 230 SEL 2011 and Harris Flotebote Super Sunliner 240 SSL 2007 from the same manufacturer?
Yes — both the Harris Flotebote Grand Mariner 230 SEL 2011 and the Harris Flotebote Super Sunliner 240 SSL 2007 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.
