Harris Flotebote Grand Mariner 230 SE 2009 vs Harris Flotebote Grand Mariner SEL 230 2013 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the Harris Flotebote Grand Mariner 230 SE 2009 and the Harris Flotebote Grand Mariner SEL 230 2013 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 230 SE 2009 at 25,0 ft versus Harris Flotebote Grand Mariner SEL 230 2013 at 25,7 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner 230 SE 2009 tips the scales at 4 324 lbs — 298 lbs more than the Harris Flotebote Grand Mariner SEL 230 2013 at 4 026 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 40-hp advantage over the Harris Flotebote Grand Mariner 230 SE 2009's 260-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 14 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: Performance buyers should lean toward the Harris Flotebote Grand Mariner SEL 230 2013 and its 300-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Harris Flotebote Grand Mariner 230 SE 2009 with its 260-hp rating is the more economical daily driver.

Harris Flotebote Grand Mariner 230 SE 2009 vs Harris Flotebote Grand Mariner SEL 230 2013 — Common Questions

Which is the larger boat — the Harris Flotebote Grand Mariner 230 SE 2009 or the Harris Flotebote Grand Mariner SEL 230 2013?
The Harris Flotebote Grand Mariner SEL 230 2013 is the longer of the two at 25,7 feet overall. The Harris Flotebote Grand Mariner 230 SE 2009 comes in at 25,0 feet, making it roughly 0,7 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Grand Mariner 230 SE 2009 or the Harris Flotebote Grand Mariner SEL 230 2013?
For trailering, the Harris Flotebote Grand Mariner SEL 230 2013 has the edge at 4 026 lbs dry weight versus 4 324 lbs for the Harris Flotebote Grand Mariner 230 SE 2009. 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 Grand Mariner 230 SE 2009 tops out at 260 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 SE 2009 is Coast Guard rated for 14 passengers, while the Harris Flotebote Grand Mariner SEL 230 2013 is certified for 14. 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 SE 2009 and Harris Flotebote Grand Mariner SEL 230 2013 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 SE 2009 and Harris Flotebote Grand Mariner SEL 230 2013 from the same manufacturer?
Yes — both the Harris Flotebote Grand Mariner 230 SE 2009 and the Harris Flotebote Grand Mariner SEL 230 2013 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.
