When two boats share the same hull type — in this case both the Sea Chaser 160 FS 2008 and the Sea Chaser 1800 RG 2011 are modified vee 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?

On paper these two are close siblings in the size department — Sea Chaser 160 FS 2008 at 15,0 ft versus Sea Chaser 1800 RG 2011 at 18,0 ft. Weight tells a clearer story for trailering families: the Sea Chaser 1800 RG 2011 tips the scales at 155 lbs — 143 lbs less than the Sea Chaser 160 FS 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 115 hp, the Sea Chaser 1800 RG 2011 has a 25-hp advantage over the Sea Chaser 160 FS 2008's 90-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 160 FS 2008 carries 25 gallons versus 3 gallons in the Sea Chaser 1800 RG 2011. 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 2011 is rated for 5 passengers, while the Sea Chaser 160 FS 2008 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Chaser 1800 RG 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sea Chaser 160 FS 2008 comes in at 0 lbs per hp versus 1 lbs per hp for the Sea Chaser 1800 RG 2011. 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.
