Harris Flotebote Grand Mariner SEL 250 2012 vs Harris Flotebote Solstice 240 2013: A Close Look at Two Pontoon Boats

Both the Harris Flotebote Grand Mariner SEL 250 2012 and the Harris Flotebote Solstice 240 2013 are pontoon designs, the first built in fibreglass and the second in aluminium, so 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 240 2013 at 25,3 ft. At 3 537 lbs and 3 588 lbs respectively, both sit in a similar weight class - either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling - 3 hp for the Harris Flotebote Grand Mariner SEL 250 2012 and 2 hp for the Harris Flotebote Solstice 240 2013. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Harris Flotebote Grand Mariner SEL 250 2012 carries 81 gallons versus 50 gallons in the Harris Flotebote Solstice 240 2013. 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 240 2013 caps at 2. 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 240 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.

The Harris Flotebote Grand Mariner SEL 250 2012 is Coast Guard rated for 225 passengers, while the Harris Flotebote Solstice 240 2013 is certified for 2.

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 240 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.
