Detailed Evaluation & Buyer Recommendation
Boston Whaler 305 Conquest 2006 vs Boston Whaler 345 Conquest 2007 — Same Brand, Different Boat
The Boston Whaler 305 Conquest 2006 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 32,0 additional feet of deck space compared to the Boston Whaler 305 Conquest 2006 at 3,0 feet (2006). At 85 lbs and 142 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 750 hp, the Boston Whaler 345 Conquest 2007 has a 150-hp advantage over the Boston Whaler 305 Conquest 2006's 600-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 3 gallons in the Boston Whaler 305 Conquest 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 14 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The Boston Whaler 345 Conquest 2007 at 35,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Boston Whaler 305 Conquest 2006 at 3,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
