Sea Chaser 1800 RG 2007 vs Sea Chaser 1800 RG 2009 — Same Brand, Different Boat

The Sea Chaser 1800 RG 2007 vs Sea Chaser 1800 RG 2009 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 1800 RG 2007 at 18,0 ft versus Sea Chaser 1800 RG 2009 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.

Both boats share a closely matched power ceiling — 115 hp for the Sea Chaser 1800 RG 2007 and 115 hp for the Sea Chaser 1800 RG 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 3 gal and 3 gal — so range won't be a tiebreaker here.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Sea Chaser 1800 RG 2009 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: The Sea Chaser 1800 RG 2007 and Sea Chaser 1800 RG 2009 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.

Sea Chaser 1800 RG 2007 vs Sea Chaser 1800 RG 2009 — Common Questions

Which is the larger boat — the Sea Chaser 1800 RG 2007 or the Sea Chaser 1800 RG 2009?
The Sea Chaser 1800 RG 2009 is the longer of the two at 18,0 feet overall. The Sea Chaser 1800 RG 2007 comes in at 18,0 feet, making it roughly 0,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Chaser 1800 RG 2007 or the Sea Chaser 1800 RG 2009?
For trailering, the Sea Chaser 1800 RG 2009 has the edge at 155 lbs dry weight versus 155 lbs for the Sea Chaser 1800 RG 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.
How many people can each boat hold?
The Sea Chaser 1800 RG 2007 is Coast Guard rated for 5 passengers, while the Sea Chaser 1800 RG 2009 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 1800 RG 2009 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Sea Chaser 1800 RG 2007 and Sea Chaser 1800 RG 2009 share an 95.5 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
How do the fuel tanks compare on the Sea Chaser 1800 RG 2007 and Sea Chaser 1800 RG 2009?
Both boats carry similar fuel loads — 3 gallons and 3 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sea Chaser 1800 RG 2007 and Sea Chaser 1800 RG 2009 from the same manufacturer?
Yes — both the Sea Chaser 1800 RG 2007 and the Sea Chaser 1800 RG 2009 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.
