Doral 170 Sunquest 2008 vs Doral 455 Alegria 2011 — Same Brand, Different Boat

Matching a modified vee Doral 170 Sunquest 2008 against a deep vee Doral 455 Alegria 2011 means you're likely deciding between two genuinely 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 Doral 455 Alegria 2011 measures 51,3 feet overall (2011), giving it roughly 35,3 additional feet of deck space compared to the Doral 170 Sunquest 2008 at 16,0 feet (2008). At 13 lbs and 3 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.

For family outings this is probably the sharpest distinction between the two. The Doral 455 Alegria 2011 is rated for 15 passengers, while the Doral 170 Sunquest 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Doral 455 Alegria 2011 could be the deciding factor.

Bottom line: Choose the Doral 455 Alegria 2011 if your priority is putting more people on the water — it handles 15 passengers and at 51,3 ft it has the deck room to back that rating up comfortably. The Doral 170 Sunquest 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Doral 170 Sunquest 2008 vs Doral 455 Alegria 2011 — Common Questions

Which is the larger boat — the Doral 170 Sunquest 2008 or the Doral 455 Alegria 2011?
The Doral 455 Alegria 2011 is the longer of the two at 51,3 feet overall. The Doral 170 Sunquest 2008 comes in at 16,0 feet, making it roughly 35,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Doral 170 Sunquest 2008 or the Doral 455 Alegria 2011?
For trailering, the Doral 455 Alegria 2011 has the edge at 3 lbs dry weight versus 13 lbs for the Doral 170 Sunquest 2008. 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.
How many people can each boat hold?
The Doral 170 Sunquest 2008 is Coast Guard rated for 5 passengers, while the Doral 455 Alegria 2011 is certified for 15. 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 Doral 455 Alegria 2011 measures 166" wide, compared to 82" for the Doral 170 Sunquest 2008. 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.
Which boat has the larger fuel tank — the Doral 170 Sunquest 2008 or the Doral 455 Alegria 2011?
The Doral 170 Sunquest 2008 has the bigger tank at 23 gallons, versus 2 gallons on the Doral 455 Alegria 2011. That 21-gallon difference translates to roughly 63–105 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Doral 170 Sunquest 2008 and Doral 455 Alegria 2011 from the same manufacturer?
Yes — both the Doral 170 Sunquest 2008 and the Doral 455 Alegria 2011 are built by Doral. 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.
