Premier Boats Alante 251 2006 vs Premier Boats SunSpree 180 FS 2009 — Same Brand, Different Boat

The Premier Boats Alante 251 2006 vs Premier Boats SunSpree 180 FS 2009 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 Premier Boats Alante 251 2006 measures 26,0 feet overall (2006), giving it roughly 8,0 additional feet of deck space compared to the Premier Boats SunSpree 180 FS 2009 at 18,0 feet (2009). At 245 lbs and 165 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.

The power gap is worth calling out. Rated to 140 hp, the Premier Boats Alante 251 2006 has a 65-hp advantage over the Premier Boats SunSpree 180 FS 2009's 75-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 Premier Boats Alante 251 2006 is rated for 14 passengers, while the Premier Boats SunSpree 180 FS 2009 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Premier Boats Alante 251 2006 could be the deciding factor.

Bottom line: Choose the Premier Boats Alante 251 2006 if your priority is putting more people on the water — it handles 14 passengers and at 26,0 ft it has the deck room to back that rating up comfortably. The Premier Boats SunSpree 180 FS 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

Premier Boats Alante 251 2006 vs Premier Boats SunSpree 180 FS 2009 — Common Questions

Which is the larger boat — the Premier Boats Alante 251 2006 or the Premier Boats SunSpree 180 FS 2009?
The Premier Boats Alante 251 2006 is the longer of the two at 26,0 feet overall. The Premier Boats SunSpree 180 FS 2009 comes in at 18,0 feet, making it roughly 8,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Premier Boats Alante 251 2006 or the Premier Boats SunSpree 180 FS 2009?
For trailering, the Premier Boats SunSpree 180 FS 2009 has the edge at 165 lbs dry weight versus 245 lbs for the Premier Boats Alante 251 2006. 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 Premier Boats Alante 251 2006 is rated to a maximum of 140 hp, giving it the larger power ceiling. The Premier Boats SunSpree 180 FS 2009 tops out at 75 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 Premier Boats Alante 251 2006 is Coast Guard rated for 14 passengers, while the Premier Boats SunSpree 180 FS 2009 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 Premier Boats Alante 251 2006 and Premier Boats SunSpree 180 FS 2009 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 Premier Boats Alante 251 2006 and Premier Boats SunSpree 180 FS 2009 from the same manufacturer?
Yes — both the Premier Boats Alante 251 2006 and the Premier Boats SunSpree 180 FS 2009 are built by Premier Boats. 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.
