Harris Flotebote Grand Mariner SEL 250 2012 vs Harris Flotebote Solstice 270 2011 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner SEL 250 2012 and the Harris Flotebote Solstice 270 2011 are pontoon designs with fiberglass 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 SEL 250 2012 at 27,3 ft versus Harris Flotebote Solstice 270 2011 at 27,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SEL 250 2012 tips the scales at 3 537 lbs — 180 lbs more than the Harris Flotebote Solstice 270 2011 at 3 357 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 175 hp, the Harris Flotebote Solstice 270 2011 has a 172-hp advantage over the Harris Flotebote Grand Mariner SEL 250 2012's 3-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Harris Flotebote Grand Mariner SEL 250 2012 carries 81 gallons versus 5 gallons in the Harris Flotebote Solstice 270 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Grand Mariner SEL 250 2012 is rated for 225 passengers, while the Harris Flotebote Solstice 270 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Grand Mariner SEL 250 2012 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Grand Mariner SEL 250 2012 if your priority is putting more people on the water — it handles 225 passengers and at 27,3 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Solstice 270 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

Harris Flotebote Grand Mariner SEL 250 2012 vs Harris Flotebote Solstice 270 2011 — Common Questions

Which is the larger boat — the Harris Flotebote Grand Mariner SEL 250 2012 or the Harris Flotebote Solstice 270 2011?
The Harris Flotebote Grand Mariner SEL 250 2012 is the longer of the two at 27,3 feet overall. The Harris Flotebote Solstice 270 2011 comes in at 27,0 feet, making it roughly 0,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Grand Mariner SEL 250 2012 or the Harris Flotebote Solstice 270 2011?
For trailering, the Harris Flotebote Solstice 270 2011 has the edge at 3 357 lbs dry weight versus 3 537 lbs for the Harris Flotebote Grand Mariner SEL 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 Solstice 270 2011 is rated to a maximum of 175 hp, giving it the larger power ceiling. The Harris Flotebote Grand Mariner SEL 250 2012 tops out at 3 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 250 2012 is Coast Guard rated for 225 passengers, while the Harris Flotebote Solstice 270 2011 is certified for 12. 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 250 2012 and Harris Flotebote Solstice 270 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.
Which boat has the larger fuel tank — the Harris Flotebote Grand Mariner SEL 250 2012 or the Harris Flotebote Solstice 270 2011?
The Harris Flotebote Grand Mariner SEL 250 2012 has the bigger tank at 81 gallons, versus 5 gallons on the Harris Flotebote Solstice 270 2011. That 76-gallon difference translates to roughly 228–380 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Harris Flotebote Grand Mariner SEL 250 2012 and Harris Flotebote Solstice 270 2011 from the same manufacturer?
Yes — both the Harris Flotebote Grand Mariner SEL 250 2012 and the Harris Flotebote Solstice 270 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.
