Boston Whaler 315 Conquest 2018 vs Boston Whaler 370 Outrage 2009 — Same Brand, Different Boat

The Boston Whaler 315 Conquest 2018 vs Boston Whaler 370 Outrage 2009 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 900 hp, the Boston Whaler 370 Outrage 2009 has a 600-hp advantage over the Boston Whaler 315 Conquest 2018's 300-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 315 Conquest 2018 carries 291 gallons versus 45 gallons in the Boston Whaler 370 Outrage 2009. 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 370 Outrage 2009 is rated for 14 passengers, while the Boston Whaler 315 Conquest 2018 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 370 Outrage 2009 could be the deciding factor.

Bottom line: Choose the Boston Whaler 370 Outrage 2009 if your priority is putting more people on the water — it handles 14 passengers and at 37,0 ft it has the deck room to back that rating up comfortably. The Boston Whaler 315 Conquest 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.

The Boston Whaler 370 Outrage 2009 is the longer of the two at 37,0 feet overall. The Boston Whaler 315 Conquest 2018 comes in at 31,3 feet, making it roughly 5,7 ft shorter — a meaningful difference in deck room and overall on-water presence.

How many people can each boat hold?
The Boston Whaler 315 Conquest 2018 is Coast Guard rated for 9 passengers, while the Boston Whaler 370 Outrage 2009 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 370 Outrage 2009 measures 138" wide, compared to 130" for the Boston Whaler 315 Conquest 2018. 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.

The Boston Whaler 315 Conquest 2018 has the bigger tank at 291 gallons, versus 45 gallons on the Boston Whaler 370 Outrage 2009. That 246-gallon difference translates to roughly 738–1230 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

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.
