Boston Whaler 150 Montauk 2006 vs Boston Whaler 255 Conquest 2011 — Same Brand, Different Boat

The Boston Whaler 150 Montauk 2006 vs Boston Whaler 255 Conquest 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 Boston Whaler 255 Conquest 2011 measures 26,9 feet overall (2011), giving it roughly 11,9 additional feet of deck space compared to the Boston Whaler 150 Montauk 2006 at 15,0 feet (2006). At 95 lbs and 49 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 450 hp, the Boston Whaler 255 Conquest 2011 has a 390-hp advantage over the Boston Whaler 150 Montauk 2006's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 13 gal and 15 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Boston Whaler 255 Conquest 2011 is rated for 14 passengers, while the Boston Whaler 150 Montauk 2006 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 255 Conquest 2011 could be the deciding factor.

Bottom line: Choose the Boston Whaler 255 Conquest 2011 if your priority is putting more people on the water — it handles 14 passengers and at 26,9 ft it has the deck room to back that rating up comfortably. The Boston Whaler 150 Montauk 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Boston Whaler 150 Montauk 2006 vs Boston Whaler 255 Conquest 2011 — Common Questions

Which is the larger boat — the Boston Whaler 150 Montauk 2006 or the Boston Whaler 255 Conquest 2011?
The Boston Whaler 255 Conquest 2011 is the longer of the two at 26,9 feet overall. The Boston Whaler 150 Montauk 2006 comes in at 15,0 feet, making it roughly 11,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Boston Whaler 150 Montauk 2006 or the Boston Whaler 255 Conquest 2011?
For trailering, the Boston Whaler 255 Conquest 2011 has the edge at 49 lbs dry weight versus 95 lbs for the Boston Whaler 150 Montauk 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 Boston Whaler 255 Conquest 2011 is rated to a maximum of 450 hp, giving it the larger power ceiling. The Boston Whaler 150 Montauk 2006 tops out at 60 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 Boston Whaler 150 Montauk 2006 is Coast Guard rated for 6 passengers, while the Boston Whaler 255 Conquest 2011 is certified for 14. 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.
Which boat is wider, and does it affect trailering?
The Boston Whaler 255 Conquest 2011 measures 105" wide, compared to 78" for the Boston Whaler 150 Montauk 2006. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
How do the fuel tanks compare on the Boston Whaler 150 Montauk 2006 and Boston Whaler 255 Conquest 2011?
Both boats carry similar fuel loads — 13 gallons and 15 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Boston Whaler 150 Montauk 2006 and Boston Whaler 255 Conquest 2011 from the same manufacturer?
Yes — both the Boston Whaler 150 Montauk 2006 and the Boston Whaler 255 Conquest 2011 are built by Boston Whaler. 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.
