When two boats share the same hull type — in this case both the Boston Whaler 150 Super Sport 2011 and the Boston Whaler 345 Conquest 2008 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Boston Whaler 345 Conquest 2008 measures 35,0 feet overall (2008), giving it roughly 19,7 additional feet of deck space compared to the Boston Whaler 150 Super Sport 2011 at 15,3 feet (2011). Weight tells a clearer story for trailering families: the Boston Whaler 345 Conquest 2008 tips the scales at 142 lbs — 133 lbs less than the Boston Whaler 150 Super Sport 2011 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 2008 has a 690-hp advantage over the Boston Whaler 150 Super Sport 2011'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 2008 carries 421 gallons versus 7 gallons in the Boston Whaler 150 Super Sport 2011. 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 2008 is rated for 14 passengers, while the Boston Whaler 150 Super Sport 2011 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 2008 could be the deciding factor.
