When two boats share the same hull type — in this case both the Fun Chaser 1900 DS Fish 2011 and the Fun Chaser FGP 2100 Cruiser 2013 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 — Fun Chaser 1900 DS Fish 2011 at 19,0 ft versus Fun Chaser FGP 2100 Cruiser 2013 at 21,3 ft. Weight tells a clearer story for trailering families: the Fun Chaser FGP 2100 Cruiser 2013 tips the scales at 3 375 lbs — 3 354 lbs less than the Fun Chaser 1900 DS Fish 2011 at 21 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 Fun Chaser 1900 DS Fish 2011 and 150 hp for the Fun Chaser FGP 2100 Cruiser 2013. 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.
For family outings this is probably the sharpest distinction between the two. The Fun Chaser FGP 2100 Cruiser 2013 is rated for 14 passengers, while the Fun Chaser 1900 DS Fish 2011 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fun Chaser FGP 2100 Cruiser 2013 could be the deciding factor.
Bottom line: Choose the Fun Chaser FGP 2100 Cruiser 2013 if your priority is putting more people on the water — it handles 14 passengers and at 21,3 ft it has the deck room to back that rating up comfortably. The Fun Chaser 1900 DS Fish 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
