Q: Which is the larger boat - the Harris Flotebote Grand Mariner SEL 230 2013 or the Harris Flotebote Sunliner 180 2005?

The Harris Flotebote Grand Mariner SEL 230 2013 is the longer of the two at 25,7 feet overall. The Harris Flotebote Sunliner 180 2005 comes in at 18,0 feet, making it roughly 7,7 ft shorter - a meaningful difference in deck room and overall on-water presence.

Q: Which is easier to trailer - the Harris Flotebote Grand Mariner SEL 230 2013 or the Harris Flotebote Sunliner 180 2005?

For trailering, the Harris Flotebote Sunliner 180 2005 has the edge at 1 770 lbs dry weight versus 4 026 lbs for the Harris Flotebote Grand Mariner SEL 230 2013. 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.

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 Sunliner 180 2005 tops out at 23 hp.

The Harris Flotebote Grand Mariner SEL 230 2013 is Coast Guard rated for 14 passengers, while the Harris Flotebote Sunliner 180 2005 is certified for 10.

Q: Do these boats require an oversize trailer permit to tow on US highways?

Both the Harris Flotebote Grand Mariner SEL 230 2013 and Harris Flotebote Sunliner 180 2005 share an 8 ft. 6 in. (2.6 m) 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.

Q: Are the Harris Flotebote Grand Mariner SEL 230 2013 and Harris Flotebote Sunliner 180 2005 from the same manufacturer?

Yes - both the Harris Flotebote Grand Mariner SEL 230 2013 and the Harris Flotebote Sunliner 180 2005 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.

Detailed Evaluation & Buyer Recommendation

Harris Flotebote Grand Mariner SEL 230 2013 vs Harris Flotebote Sunliner 180 2005: Same Brand, Different Boat

The Harris Flotebote Grand Mariner SEL 230 2013 vs Harris Flotebote Sunliner 180 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Harris Flotebote Grand Mariner SEL 230 2013 measures 25,7 feet overall (2013), giving it roughly 7,7 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2005 at 18,0 feet (2005). Weight tells a clearer story for trailering families: the Harris Flotebote Grand Mariner SEL 230 2013 tips the scales at 4 026 lbs - 2 256 lbs more than the Harris Flotebote Sunliner 180 2005 at 1 770 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 277-hp advantage over the Harris Flotebote Sunliner 180 2005's 23-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Grand Mariner SEL 230 2013 is rated for 14 passengers, while the Harris Flotebote Sunliner 180 2005 caps at 10. 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 230 2013 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Grand Mariner SEL 230 2013 if your priority is putting more people on the water - it handles 14 passengers and at 25,7 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Sunliner 180 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
