Both the Jetcraft 1625 Falcon 2012 and the Jetcraft 1975 Fastwater 2010 are modified-V designs, both built in aluminium, so 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 Jetcraft 1975 Fastwater 2010 measures 20,3 feet overall (2010), giving it roughly 4,3 additional feet of deck space compared to the Jetcraft 1625 Falcon 2012 at 16,0 feet (2012). Weight tells a clearer story for trailering families: the Jetcraft 1975 Fastwater 2010 tips the scales at 3 259 lbs - 2 309 lbs less than the Jetcraft 1625 Falcon 2012 at 950 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 Jetcraft 1625 Falcon 2012 carries a rated maximum of 70 hp. Engine data for the Jetcraft 1975 Fastwater 2010 wasn't available in our records - check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Jetcraft 1975 Fastwater 2010 carries 52 gallons versus 20 gallons in the Jetcraft 1625 Falcon 2012. 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 Jetcraft 1975 Fastwater 2010 is rated for 6 passengers, while the Jetcraft 1625 Falcon 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Jetcraft 1975 Fastwater 2010 could be the deciding factor.
Bottom line: Choose the Jetcraft 1975 Fastwater 2010 if your priority is putting more people on the water - it handles 6 passengers and at 20,3 ft it has the deck room to back that rating up comfortably. The Jetcraft 1625 Falcon 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
