When two boats share the same hull type — in this case both the Sea Chaser 180 FS 2010 and the Sea Chaser 1950 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 180 FS 2010 at 17,8 ft versus Sea Chaser 1950 RG 2011 at 19,6 ft. Weight tells a clearer story for trailering families: the Sea Chaser 180 FS 2010 tips the scales at 172 lbs — 155 lbs more than the Sea Chaser 1950 RG 2011 at 17 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 — 150 hp for the Sea Chaser 180 FS 2010 and 150 hp for the Sea Chaser 1950 RG 2011. 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. Fuel capacity breaks the other way: the Sea Chaser 1950 RG 2011 carries 52 gallons versus 33 gallons in the Sea Chaser 180 FS 2010. 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 1950 RG 2011 is rated for 6 passengers, while the Sea Chaser 180 FS 2010 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 1950 RG 2011 could be the deciding factor.
Bottom line: Choose the Sea Chaser 1950 RG 2011 if your priority is putting more people on the water — it handles 6 passengers and at 19,6 ft it has the deck room to back that rating up comfortably. The Sea Chaser 180 FS 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
