The Harris Flotebote Crowne 270 O/B 2005 vs Harris Flotebote Sunliner 180 2011 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 270 O/B 2005 measures 27,0 feet overall (2005), giving it roughly 9,0 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Harris Flotebote Sunliner 180 2011 tips the scales at 2 104 lbs — 1 809 lbs less than the Harris Flotebote Crowne 270 O/B 2005 at 295 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 270 O/B 2005 carries a rated maximum of 180 hp. Engine data for the Harris Flotebote Sunliner 180 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 270 O/B 2005 is rated for 18 passengers, while the Harris Flotebote Sunliner 180 2011 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 270 O/B 2005 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Crowne 270 O/B 2005 if your priority is putting more people on the water — it handles 18 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Sunliner 180 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

The Harris Flotebote Crowne 270 O/B 2005 is the longer of the two at 27,0 feet overall. The Harris Flotebote Sunliner 180 2011 comes in at 18,0 feet, making it roughly 9,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Harris Flotebote Crowne 270 O/B 2005 or the Harris Flotebote Sunliner 180 2011?
For trailering, the Harris Flotebote Crowne 270 O/B 2005 has the edge at 295 lbs dry weight versus 2 104 lbs for the Harris Flotebote Sunliner 180 2011. 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?
The Harris Flotebote Crowne 270 O/B 2005 has a documented max rating of 180 hp. Engine specifications for the Harris Flotebote Sunliner 180 2011 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Harris Flotebote Crowne 270 O/B 2005 is Coast Guard rated for 18 passengers, while the Harris Flotebote Sunliner 180 2011 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 270 O/B 2005 and Harris Flotebote Sunliner 180 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.

Yes — both the Harris Flotebote Crowne 270 O/B 2005 and the Harris Flotebote Sunliner 180 2011 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.
