When two boats share the same hull type — in this case both the Sea Cat 185 Center Console 2007 and the Sea Cat 207 SD Comet 2007 are catamaran designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Sea Cat 185 Center Console 2007 measures 17,0 feet overall (2007), giving it roughly 15,0 additional feet of deck space compared to the Sea Cat 207 SD Comet 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Cat 207 SD Comet 2007 tips the scales at 275 lbs — 140 lbs less than the Sea Cat 185 Center Console 2007 at 135 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 250 hp, the Sea Cat 207 SD Comet 2007 has a 110-hp advantage over the Sea Cat 185 Center Console 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 Sea Cat 207 SD Comet 2007 carries 74 gallons versus 52 gallons in the Sea Cat 185 Center Console 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 Cat 207 SD Comet 2007 is rated for 6 passengers, while the Sea Cat 185 Center Console 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Cat 207 SD Comet 2007 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Sea Cat 185 Center Console 2007 comes in at 1 lbs per hp versus 1 lbs per hp for the Sea Cat 207 SD Comet 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 Cat 207 SD Comet 2007 if your priority is putting more people on the water — it handles 6 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Sea Cat 185 Center Console 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.
