Harris Flotebote Crowne 250 2009 vs Harris Flotebote Grand Mariner 250 SL 2011 — A Close Look at Two Pontoons

When two boats share the same hull type — in this case both the Harris Flotebote Crowne 250 2009 and the Harris Flotebote Grand Mariner 250 SL 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 Crowne 250 2009 at 26,0 ft versus Harris Flotebote Grand Mariner 250 SL 2011 at 25,0 ft. Weight tells a clearer story for trailering families: the Harris Flotebote Crowne 250 2009 tips the scales at 2 865 lbs — 2 543 lbs more 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.

The Harris Flotebote Crowne 250 2009 carries a rated maximum of 175 hp. Engine data for the Harris Flotebote Grand Mariner 250 SL 2011 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Crowne 250 2009 is rated for 15 passengers, while the Harris Flotebote Grand Mariner 250 SL 2011 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Crowne 250 2009 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Crowne 250 2009 if your priority is putting more people on the water — it handles 15 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Grand Mariner 250 SL 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.

The Harris Flotebote Crowne 250 2009 is the longer of the two at 26,0 feet overall. The Harris Flotebote Grand Mariner 250 SL 2011 comes in at 25,0 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 Crowne 250 2009 or the Harris Flotebote Grand Mariner 250 SL 2011?
For trailering, the Harris Flotebote Grand Mariner 250 SL 2011 has the edge at 322 lbs dry weight versus 2 865 lbs for the Harris Flotebote Crowne 250 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.
What is the maximum horsepower rating for these boats?

How many people can each boat hold?
The Harris Flotebote Crowne 250 2009 is Coast Guard rated for 15 passengers, while the Harris Flotebote Grand Mariner 250 SL 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 Crowne 250 2009 and Harris Flotebote Grand Mariner 250 SL 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.
