Harris Flotebote Grand Mariner SEL 230 2013 vs Harris Flotebote Sunliner 240 2006 — Same Brand, Different Boat

The Harris Flotebote Grand Mariner SEL 230 2013 vs Harris Flotebote Sunliner 240 2006 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 SEL 230 2013 at 25,7 ft versus Harris Flotebote Sunliner 240 2006 at 24,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SEL 230 2013 tips the scales at 4 026 lbs — 3 821 lbs more than the Harris Flotebote Sunliner 240 2006 at 205 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 SEL 230 2013 has a 160-hp advantage over the Harris Flotebote Sunliner 240 2006's 140-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 Sunliner 240 2006 is rated for 18 passengers, while the Harris Flotebote Grand Mariner SEL 230 2013 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 Sunliner 240 2006 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Sunliner 240 2006 if your priority is putting more people on the water — it handles 18 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Grand Mariner SEL 230 2013 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 SEL 230 2013 vs Harris Flotebote Sunliner 240 2006 — Common Questions

Which is the larger boat — the Harris Flotebote Grand Mariner SEL 230 2013 or the Harris Flotebote Sunliner 240 2006?
The Harris Flotebote Grand Mariner SEL 230 2013 is the longer of the two at 25,7 feet overall. The Harris Flotebote Sunliner 240 2006 comes in at 24,0 feet, making it roughly 1,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Grand Mariner SEL 230 2013 or the Harris Flotebote Sunliner 240 2006?
For trailering, the Harris Flotebote Sunliner 240 2006 has the edge at 205 lbs dry weight versus 4 026 lbs for the Harris Flotebote Grand Mariner SEL 230 2013. 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 SEL 230 2013 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Harris Flotebote Sunliner 240 2006 tops out at 140 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 SEL 230 2013 is Coast Guard rated for 14 passengers, while the Harris Flotebote Sunliner 240 2006 is certified for 18. 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 SEL 230 2013 and Harris Flotebote Sunliner 240 2006 share an 8 ft. 6 in. (2.6 m) 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 SEL 230 2013 and Harris Flotebote Sunliner 240 2006 from the same manufacturer?
Yes — both the Harris Flotebote Grand Mariner SEL 230 2013 and the Harris Flotebote Sunliner 240 2006 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.
