Boston Whaler 150 Sport 2008 vs Boston Whaler 345 Conquest 2007 — Same Brand, Different Boat

The Boston Whaler 150 Sport 2008 vs Boston Whaler 345 Conquest 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 Boston Whaler 345 Conquest 2007 measures 35,0 feet overall (2007), giving it roughly 20,0 additional feet of deck space compared to the Boston Whaler 150 Sport 2008 at 15,0 feet (2008). Weight tells a clearer story for trailering families: the Boston Whaler 345 Conquest 2007 tips the scales at 142 lbs — 133 lbs less than the Boston Whaler 150 Sport 2008 at 9 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 750 hp, the Boston Whaler 345 Conquest 2007 has a 690-hp advantage over the Boston Whaler 150 Sport 2008's 60-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 2007 carries 421 gallons versus 7 gallons in the Boston Whaler 150 Sport 2008. 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 2007 is rated for 14 passengers, while the Boston Whaler 150 Sport 2008 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 345 Conquest 2007 could be the deciding factor.

Bottom line: Choose the Boston Whaler 345 Conquest 2007 if your priority is putting more people on the water — it handles 14 passengers and at 35,0 ft it has the deck room to back that rating up comfortably. The Boston Whaler 150 Sport 2008 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 Sport 2008 vs Boston Whaler 345 Conquest 2007 — Common Questions

Which is the larger boat — the Boston Whaler 150 Sport 2008 or the Boston Whaler 345 Conquest 2007?
The Boston Whaler 345 Conquest 2007 is the longer of the two at 35,0 feet overall. The Boston Whaler 150 Sport 2008 comes in at 15,0 feet, making it roughly 20,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Boston Whaler 150 Sport 2008 or the Boston Whaler 345 Conquest 2007?
For trailering, the Boston Whaler 150 Sport 2008 has the edge at 9 lbs dry weight versus 142 lbs for the Boston Whaler 345 Conquest 2007. 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 345 Conquest 2007 is rated to a maximum of 750 hp, giving it the larger power ceiling. The Boston Whaler 150 Sport 2008 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 Sport 2008 is Coast Guard rated for 6 passengers, while the Boston Whaler 345 Conquest 2007 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 150 Sport 2008 measures 78" wide, compared to 14" for the Boston Whaler 345 Conquest 2007. 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 150 Sport 2008 or the Boston Whaler 345 Conquest 2007?
The Boston Whaler 345 Conquest 2007 has the bigger tank at 421 gallons, versus 7 gallons on the Boston Whaler 150 Sport 2008. That 414-gallon difference translates to roughly 1243–2072 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Boston Whaler 150 Sport 2008 and Boston Whaler 345 Conquest 2007 from the same manufacturer?
Yes — both the Boston Whaler 150 Sport 2008 and the Boston Whaler 345 Conquest 2007 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.
