Harris Flotebote Grand Mariner 250 SL 2011 vs Harris Flotebote Sunliner 240 2011 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner 250 SL 2011 and the Harris Flotebote Sunliner 240 2011 are pontoon designs with aluminum construction — 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?

On paper these two are close siblings in the size department — Harris Flotebote Grand Mariner 250 SL 2011 at 25,0 ft versus Harris Flotebote Sunliner 240 2011 at 24,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Sunliner 240 2011 tips the scales at 2 835 lbs — 2 513 lbs less than the Harris Flotebote Grand Mariner 250 SL 2011 at 322 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.

Both boats are rated for 13 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Harris Flotebote Grand Mariner 250 SL 2011 and Harris Flotebote Sunliner 240 2011 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Harris Flotebote Grand Mariner 250 SL 2011 vs Harris Flotebote Sunliner 240 2011 — Common Questions

Which is the larger boat — the Harris Flotebote Grand Mariner 250 SL 2011 or the Harris Flotebote Sunliner 240 2011?
The Harris Flotebote Grand Mariner 250 SL 2011 is the longer of the two at 25,0 feet overall. The Harris Flotebote Sunliner 240 2011 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 Grand Mariner 250 SL 2011 or the Harris Flotebote Sunliner 240 2011?
For trailering, the Harris Flotebote Grand Mariner 250 SL 2011 has the edge at 322 lbs dry weight versus 2 835 lbs for the Harris Flotebote Sunliner 240 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.
How many people can each boat hold?
The Harris Flotebote Grand Mariner 250 SL 2011 is Coast Guard rated for 13 passengers, while the Harris Flotebote Sunliner 240 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 Grand Mariner 250 SL 2011 and Harris Flotebote Sunliner 240 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.
How do the fuel tanks compare on the Harris Flotebote Grand Mariner 250 SL 2011 and Harris Flotebote Sunliner 240 2011?
Both boats carry similar fuel loads — 5 gallons and 5 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Harris Flotebote Grand Mariner 250 SL 2011 and Harris Flotebote Sunliner 240 2011 from the same manufacturer?
Yes — both the Harris Flotebote Grand Mariner 250 SL 2011 and the Harris Flotebote Sunliner 240 2011 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.
