Seaswirl 175 Fish-N-Ski O/B 2007 vs Seaswirl 3301 Walkaround O/B 2008 — Same Brand, Different Boat

The Seaswirl 175 Fish-N-Ski O/B 2007 vs Seaswirl 3301 Walkaround O/B 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 3301 Walkaround O/B 2008 measures 33,0 feet overall (2008), giving it roughly 16,0 additional feet of deck space compared to the Seaswirl 175 Fish-N-Ski O/B 2007 at 17,0 feet (2007). Weight tells a clearer story for trailering families: the Seaswirl 175 Fish-N-Ski O/B 2007 tips the scales at 205 lbs — 193 lbs more than the Seaswirl 3301 Walkaround O/B 2008 at 12 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 600 hp, the Seaswirl 3301 Walkaround O/B 2008 has a 460-hp advantage over the Seaswirl 175 Fish-N-Ski O/B 2007's 140-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 3301 Walkaround O/B 2008 carries 347 gallons versus 23 gallons in the Seaswirl 175 Fish-N-Ski O/B 2007. 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 3301 Walkaround O/B 2008 is rated for 10 passengers, while the Seaswirl 175 Fish-N-Ski O/B 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Seaswirl 3301 Walkaround O/B 2008 could be the deciding factor.

Bottom line: Choose the Seaswirl 3301 Walkaround O/B 2008 if your priority is putting more people on the water — it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Seaswirl 175 Fish-N-Ski O/B 2007 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 175 Fish-N-Ski O/B 2007 vs Seaswirl 3301 Walkaround O/B 2008 — Common Questions

Which is the larger boat — the Seaswirl 175 Fish-N-Ski O/B 2007 or the Seaswirl 3301 Walkaround O/B 2008?
The Seaswirl 3301 Walkaround O/B 2008 is the longer of the two at 33,0 feet overall. The Seaswirl 175 Fish-N-Ski O/B 2007 comes in at 17,0 feet, making it roughly 16,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Seaswirl 175 Fish-N-Ski O/B 2007 or the Seaswirl 3301 Walkaround O/B 2008?
For trailering, the Seaswirl 3301 Walkaround O/B 2008 has the edge at 12 lbs dry weight versus 205 lbs for the Seaswirl 175 Fish-N-Ski O/B 2007. 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 3301 Walkaround O/B 2008 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Seaswirl 175 Fish-N-Ski O/B 2007 tops out at 140 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 175 Fish-N-Ski O/B 2007 is Coast Guard rated for 5 passengers, while the Seaswirl 3301 Walkaround O/B 2008 is certified for 10. 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 3301 Walkaround O/B 2008 measures 132" wide, compared to 93" for the Seaswirl 175 Fish-N-Ski O/B 2007. 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 175 Fish-N-Ski O/B 2007 or the Seaswirl 3301 Walkaround O/B 2008?
The Seaswirl 3301 Walkaround O/B 2008 has the bigger tank at 347 gallons, versus 23 gallons on the Seaswirl 175 Fish-N-Ski O/B 2007. That 324-gallon difference translates to roughly 972–1620 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Seaswirl 175 Fish-N-Ski O/B 2007 and Seaswirl 3301 Walkaround O/B 2008 from the same manufacturer?
Yes — both the Seaswirl 175 Fish-N-Ski O/B 2007 and the Seaswirl 3301 Walkaround O/B 2008 are built by Seaswirl. 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.
