When two boats share the same hull type — in this case both the Action Craft 1622 FlyFisher 2009 and the Action Craft 1820 Flats Master 2008 are other 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 — Action Craft 1622 FlyFisher 2009 at 16,0 ft versus Action Craft 1820 Flats Master 2008 at 18,0 ft. Weight tells a clearer story for trailering families: the Action Craft 1820 Flats Master 2008 tips the scales at 975 lbs — 180 lbs less than the Action Craft 1622 FlyFisher 2009 at 795 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 150 hp, the Action Craft 1820 Flats Master 2008 has a 35-hp advantage over the Action Craft 1622 FlyFisher 2009's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Action Craft 1820 Flats Master 2008 carries 45 gallons versus 26 gallons in the Action Craft 1622 FlyFisher 2009. 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 Action Craft 1820 Flats Master 2008 is rated for 5 passengers, while the Action Craft 1622 FlyFisher 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Action Craft 1820 Flats Master 2008 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Action Craft 1820 Flats Master 2008 comes in at 7 lbs per hp versus 7 lbs per hp for the Action Craft 1622 FlyFisher 2009. 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.
Bottom line: Choose the Action Craft 1820 Flats Master 2008 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Action Craft 1622 FlyFisher 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
