Boston Whaler 270 Vantage 2015 vs Boston Whaler 345 Conquest 2010 — Same Brand, Different Boat

The Boston Whaler 270 Vantage 2015 vs Boston Whaler 345 Conquest 2010 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.

The power gap is worth calling out. Rated to 900 hp, the Boston Whaler 345 Conquest 2010 has a 675-hp advantage over the Boston Whaler 270 Vantage 2015's 225-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Boston Whaler 345 Conquest 2010 carries 347 gallons versus 175 gallons in the Boston Whaler 270 Vantage 2015. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Boston Whaler 345 Conquest 2010 is rated for 14 passengers, while the Boston Whaler 270 Vantage 2015 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 345 Conquest 2010 could be the deciding factor.

Bottom line: Choose the Boston Whaler 345 Conquest 2010 if your priority is putting more people on the water — it handles 14 passengers and at 35,9 ft it has the deck room to back that rating up comfortably. The Boston Whaler 270 Vantage 2015 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 8 that costs less to run day-to-day.

Boston Whaler 270 Vantage 2015 vs Boston Whaler 345 Conquest 2010 — Common Questions

Which is the larger boat — the Boston Whaler 270 Vantage 2015 or the Boston Whaler 345 Conquest 2010?
The Boston Whaler 345 Conquest 2010 is the longer of the two at 35,9 feet overall. The Boston Whaler 270 Vantage 2015 comes in at 28,3 feet, making it roughly 7,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Boston Whaler 345 Conquest 2010 is rated to a maximum of 900 hp, giving it the larger power ceiling. The Boston Whaler 270 Vantage 2015 tops out at 225 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 270 Vantage 2015 is Coast Guard rated for 8 passengers, while the Boston Whaler 345 Conquest 2010 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 270 Vantage 2015 measures 108" wide, compared to 14" for the Boston Whaler 345 Conquest 2010. 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.
Which boat has the larger fuel tank — the Boston Whaler 270 Vantage 2015 or the Boston Whaler 345 Conquest 2010?
The Boston Whaler 345 Conquest 2010 has the bigger tank at 347 gallons, versus 175 gallons on the Boston Whaler 270 Vantage 2015. That 172-gallon difference translates to roughly 516–860 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Boston Whaler 270 Vantage 2015 and the Boston Whaler 345 Conquest 2010 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.
