When two boats share the same hull type — in this case both the Sea Chaser 160 FS 2012 and the Sea Chaser 175 RG 2010 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 2012 at 15,8 ft versus Sea Chaser 175 RG 2010 at 17,4 ft. Weight tells a clearer story for trailering families: the Sea Chaser 175 RG 2010 tips the scales at 131 lbs — 119 lbs less than the Sea Chaser 160 FS 2012 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.

Both boats share a closely matched power ceiling — 90 hp for the Sea Chaser 160 FS 2012 and 100 hp for the Sea Chaser 175 RG 2010. 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 — 25 gal and 25 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Chaser 175 RG 2010 is rated for 4 passengers, while the Sea Chaser 160 FS 2012 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 175 RG 2010 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Sea Chaser 160 FS 2012 comes in at 0 lbs per hp versus 1 lbs per hp for the Sea Chaser 175 RG 2010. 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.
