Boston Whaler 345 Conquest 2022 vs Boston Whaler 380 Ream 2023 — Same Brand, Different Boat

The Boston Whaler 345 Conquest 2022 vs Boston Whaler 380 Ream 2023 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 300 hp, the Boston Whaler 380 Ream 2023 has a 50-hp advantage over the Boston Whaler 345 Conquest 2022's 250-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 380 Ream 2023 carries 445 gallons versus 4 gallons in the Boston Whaler 345 Conquest 2022. 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 380 Ream 2023 is rated for 11 passengers, while the Boston Whaler 345 Conquest 2022 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 380 Ream 2023 could be the deciding factor.

Bottom line: Choose the Boston Whaler 380 Ream 2023 if your priority is putting more people on the water — it handles 11 passengers and at 38,0 ft it has the deck room to back that rating up comfortably. The Boston Whaler 345 Conquest 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.

Boston Whaler 345 Conquest 2022 vs Boston Whaler 380 Ream 2023 — Common Questions

Which is the larger boat — the Boston Whaler 345 Conquest 2022 or the Boston Whaler 380 Ream 2023?
The Boston Whaler 380 Ream 2023 is the longer of the two at 38,0 feet overall. The Boston Whaler 345 Conquest 2022 comes in at 35,1 feet, making it roughly 2,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Boston Whaler 380 Ream 2023 is rated to a maximum of 300 hp, giving it the larger power ceiling. The Boston Whaler 345 Conquest 2022 tops out at 250 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 345 Conquest 2022 is Coast Guard rated for 10 passengers, while the Boston Whaler 380 Ream 2023 is certified for 11. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Boston Whaler 345 Conquest 2022 and Boston Whaler 380 Ream 2023 share an 11.80 ft beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Boston Whaler 345 Conquest 2022 or the Boston Whaler 380 Ream 2023?
The Boston Whaler 380 Ream 2023 has the bigger tank at 445 gallons, versus 4 gallons on the Boston Whaler 345 Conquest 2022. That 441-gallon difference translates to roughly 1323–2205 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Boston Whaler 345 Conquest 2022 and Boston Whaler 380 Ream 2023 from the same manufacturer?
Yes — both the Boston Whaler 345 Conquest 2022 and the Boston Whaler 380 Ream 2023 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.
