Seaswirl 1851 Dual Console O/B 2006 vs Seaswirl 24 Center Console 2008 — Same Brand, Different Boat

The Seaswirl 1851 Dual Console O/B 2006 vs Seaswirl 24 Center Console 2008 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.

Size is the most obvious dividing line here. The Seaswirl 24 Center Console 2008 measures 24,0 feet overall (2008), giving it roughly 6,0 additional feet of deck space compared to the Seaswirl 1851 Dual Console O/B 2006 at 18,0 feet (2006). Weight tells a clearer story for trailering families: the Seaswirl 1851 Dual Console O/B 2006 tips the scales at 255 lbs — 220 lbs more than the Seaswirl 24 Center Console 2008 at 35 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 400 hp, the Seaswirl 24 Center Console 2008 has a 225-hp advantage over the Seaswirl 1851 Dual Console O/B 2006's 175-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Seaswirl 24 Center Console 2008 carries 165 gallons versus 62 gallons in the Seaswirl 1851 Dual Console O/B 2006. 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 Seaswirl 24 Center Console 2008 is rated for 7 passengers, while the Seaswirl 1851 Dual Console O/B 2006 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Seaswirl 24 Center Console 2008 could be the deciding factor.

Bottom line: Choose the Seaswirl 24 Center Console 2008 if your priority is putting more people on the water — it handles 7 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The Seaswirl 1851 Dual Console O/B 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.

Seaswirl 1851 Dual Console O/B 2006 vs Seaswirl 24 Center Console 2008 — Common Questions

Which is the larger boat — the Seaswirl 1851 Dual Console O/B 2006 or the Seaswirl 24 Center Console 2008?
The Seaswirl 24 Center Console 2008 is the longer of the two at 24,0 feet overall. The Seaswirl 1851 Dual Console O/B 2006 comes in at 18,0 feet, making it roughly 6,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Seaswirl 1851 Dual Console O/B 2006 or the Seaswirl 24 Center Console 2008?
For trailering, the Seaswirl 24 Center Console 2008 has the edge at 35 lbs dry weight versus 255 lbs for the Seaswirl 1851 Dual Console O/B 2006. 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 Seaswirl 24 Center Console 2008 is rated to a maximum of 400 hp, giving it the larger power ceiling. The Seaswirl 1851 Dual Console O/B 2006 tops out at 175 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 Seaswirl 1851 Dual Console O/B 2006 is Coast Guard rated for 5 passengers, while the Seaswirl 24 Center Console 2008 is certified for 7. 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 Seaswirl 24 Center Console 2008 measures 102" wide, compared to 9" for the Seaswirl 1851 Dual Console O/B 2006. 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 Seaswirl 1851 Dual Console O/B 2006 or the Seaswirl 24 Center Console 2008?
The Seaswirl 24 Center Console 2008 has the bigger tank at 165 gallons, versus 62 gallons on the Seaswirl 1851 Dual Console O/B 2006. That 103-gallon difference translates to roughly 309–515 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Seaswirl 1851 Dual Console O/B 2006 and Seaswirl 24 Center Console 2008 from the same manufacturer?
Yes — both the Seaswirl 1851 Dual Console O/B 2006 and the Seaswirl 24 Center Console 2008 are built by Seaswirl. That means shared dealer networks, common parts availability, and consistent build quality across the line.
