Sea Chaser 180 Flats 2007 vs Sea Chaser 1800 RG 2007 — Same Brand, Different Boat

The Sea Chaser 180 Flats 2007 vs Sea Chaser 1800 RG 2007 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.

On paper these two are close siblings in the size department — Sea Chaser 180 Flats 2007 at 17,0 ft versus Sea Chaser 1800 RG 2007 at 18,0 ft. At 155 lbs and 155 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.

The power gap is worth calling out. Rated to 150 hp, the Sea Chaser 180 Flats 2007 has a 35-hp advantage over the Sea Chaser 1800 RG 2007's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Chaser 180 Flats 2007 carries 33 gallons versus 3 gallons in the Sea Chaser 1800 RG 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 Sea Chaser 1800 RG 2007 is rated for 5 passengers, while the Sea Chaser 180 Flats 2007 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Chaser 1800 RG 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sea Chaser 180 Flats 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Sea Chaser 1800 RG 2007. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Bottom line: Choose the Sea Chaser 1800 RG 2007 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Sea Chaser 180 Flats 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.

Sea Chaser 180 Flats 2007 vs Sea Chaser 1800 RG 2007 — Common Questions

Which is the larger boat — the Sea Chaser 180 Flats 2007 or the Sea Chaser 1800 RG 2007?
The Sea Chaser 1800 RG 2007 is the longer of the two at 18,0 feet overall. The Sea Chaser 180 Flats 2007 comes in at 17,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Chaser 180 Flats 2007 or the Sea Chaser 1800 RG 2007?
For trailering, the Sea Chaser 1800 RG 2007 has the edge at 155 lbs dry weight versus 155 lbs for the Sea Chaser 180 Flats 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 Sea Chaser 180 Flats 2007 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Sea Chaser 1800 RG 2007 tops out at 115 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 Sea Chaser 180 Flats 2007 is Coast Guard rated for 4 passengers, while the Sea Chaser 1800 RG 2007 is certified for 5. 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 has the better power-to-weight ratio?
The Sea Chaser 180 Flats 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 1 lbs per hp for the Sea Chaser 1800 RG 2007. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Sea Chaser 1800 RG 2007 measures 96" wide, compared to 85" for the Sea Chaser 180 Flats 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 Sea Chaser 180 Flats 2007 or the Sea Chaser 1800 RG 2007?
The Sea Chaser 180 Flats 2007 has the bigger tank at 33 gallons, versus 3 gallons on the Sea Chaser 1800 RG 2007. That 30-gallon difference translates to roughly 90–150 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Chaser 180 Flats 2007 and Sea Chaser 1800 RG 2007 from the same manufacturer?
Yes — both the Sea Chaser 180 Flats 2007 and the Sea Chaser 1800 RG 2007 are built by Sea Chaser. 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.
