Harris Flotebote Crowne 230 2010 vs Harris Flotebote Sunliner 180 2007: Same Brand, Different Boat

The Harris Flotebote Crowne 230 2010 vs Harris Flotebote Sunliner 180 2007 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 Crowne 230 2010 measures 23,0 feet overall (2010), giving it roughly 4,0 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2007 at 19,0 feet (2007). Weight tells a clearer story for trailering families: the Harris Flotebote Crowne 230 2010 tips the scales at 2 913 lbs - 1 138 lbs more than the Harris Flotebote Sunliner 180 2007 at 1 775 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 150 hp, the Harris Flotebote Crowne 230 2010 has a 70-hp advantage over the Harris Flotebote Sunliner 180 2007's 80-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 Crowne 230 2010 is rated for 13 passengers, while the Harris Flotebote Sunliner 180 2007 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Crowne 230 2010 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Crowne 230 2010 if your priority is putting more people on the water - it handles 13 passengers and at 23,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Sunliner 180 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Harris Flotebote Crowne 230 2010 vs Harris Flotebote Sunliner 180 2007 - Common Questions

Which is the larger boat - the Harris Flotebote Crowne 230 2010 or the Harris Flotebote Sunliner 180 2007?
The Harris Flotebote Crowne 230 2010 is the longer of the two at 23,0 feet overall. The Harris Flotebote Sunliner 180 2007 comes in at 19,0 feet, making it roughly 4,0 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Harris Flotebote Crowne 230 2010 or the Harris Flotebote Sunliner 180 2007?
For trailering, the Harris Flotebote Sunliner 180 2007 has the edge at 1 775 lbs dry weight versus 2 913 lbs for the Harris Flotebote Crowne 230 2010. 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 Crowne 230 2010 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Harris Flotebote Sunliner 180 2007 tops out at 80 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 Crowne 230 2010 is Coast Guard rated for 13 passengers, while the Harris Flotebote Sunliner 180 2007 is certified for 9. 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 230 2010 and Harris Flotebote Sunliner 180 2007 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 Crowne 230 2010 and Harris Flotebote Sunliner 180 2007 from the same manufacturer?
Yes - both the Harris Flotebote Crowne 230 2010 and the Harris Flotebote Sunliner 180 2007 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.
