Boston Whaler 110 Tender 2009 vs Boston Whaler 285 Conquest 2011: Same Brand, Different Boat

The Boston Whaler 110 Tender 2009 is a modified-V design and the Boston Whaler 285 Conquest 2011 is a deep-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Boston Whaler 285 Conquest 2011 measures 30,2 feet overall (2011), giving it roughly 19,2 additional feet of deck space compared to the Boston Whaler 110 Tender 2009 at 11,0 feet (2009). Weight tells a clearer story for trailering families: the Boston Whaler 285 Conquest 2011 tips the scales at 7 500 lbs - 7 076 lbs less than the Boston Whaler 110 Tender 2009 at 424 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 500 hp, the Boston Whaler 285 Conquest 2011 has a 485-hp advantage over the Boston Whaler 110 Tender 2009's 15-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Boston Whaler 285 Conquest 2011 is rated for 14 passengers, while the Boston Whaler 110 Tender 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Boston Whaler 285 Conquest 2011 could be the deciding factor.

Bottom line: Choose the Boston Whaler 285 Conquest 2011 if your priority is putting more people on the water - it handles 14 passengers and at 30,2 ft it has the deck room to back that rating up comfortably. The Boston Whaler 110 Tender 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Boston Whaler 110 Tender 2009 vs Boston Whaler 285 Conquest 2011 - Common Questions

Which is the larger boat - the Boston Whaler 110 Tender 2009 or the Boston Whaler 285 Conquest 2011?
The Boston Whaler 285 Conquest 2011 is the longer of the two at 30,2 feet overall. The Boston Whaler 110 Tender 2009 comes in at 11,0 feet, making it roughly 19,2 ft shorter - a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer - the Boston Whaler 110 Tender 2009 or the Boston Whaler 285 Conquest 2011?
For trailering, the Boston Whaler 110 Tender 2009 has the edge at 424 lbs dry weight versus 7 500 lbs for the Boston Whaler 285 Conquest 2011. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Boston Whaler 285 Conquest 2011 is rated to a maximum of 500 hp, giving it the larger power ceiling. The Boston Whaler 110 Tender 2009 tops out at 15 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 110 Tender 2009 is Coast Guard rated for 4 passengers, while the Boston Whaler 285 Conquest 2011 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 285 Conquest 2011 measures 116" wide, compared to 66" for the Boston Whaler 110 Tender 2009. 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.
Are the Boston Whaler 110 Tender 2009 and Boston Whaler 285 Conquest 2011 from the same manufacturer?
Yes - both the Boston Whaler 110 Tender 2009 and the Boston Whaler 285 Conquest 2011 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.
