Boston Whaler 235 Conquest 2009 vs Boston Whaler 405 Conquest 2022 — Same Brand, Different Boat

The Boston Whaler 235 Conquest 2009 vs Boston Whaler 405 Conquest 2022 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.

Both boats share a closely matched power ceiling — 300 hp for the Boston Whaler 235 Conquest 2009 and 300 hp for the Boston Whaler 405 Conquest 2022. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Boston Whaler 235 Conquest 2009 carries 122 gallons versus 62 gallons in the Boston Whaler 405 Conquest 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 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 405 Conquest 2022 at 41,4 ft is the right call if deck space, comfort, and entertaining are top of your list. The Boston Whaler 235 Conquest 2009 at 25,0 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.
