Action Craft 1720 Lightweight Hybrid 2007 vs Action Craft 1820 Flats Master 2008 — Same Brand, Different Boat

The Action Craft 1720 Lightweight Hybrid 2007 vs Action Craft 1820 Flats Master 2008 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Action Craft 1720 Lightweight Hybrid 2007 at 17,0 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 — 913 lbs less than the Action Craft 1720 Lightweight Hybrid 2007 at 62 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 25-hp advantage over the Action Craft 1720 Lightweight Hybrid 2007's 125-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 3 gallons in the Action Craft 1720 Lightweight Hybrid 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Action Craft 1720 Lightweight Hybrid 2007 comes in at 1 lbs per hp versus 7 lbs per hp for the Action Craft 1820 Flats Master 2008. 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: Performance buyers should lean toward the Action Craft 1820 Flats Master 2008 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Action Craft 1720 Lightweight Hybrid 2007 with its 125-hp rating is the more economical daily driver.

Action Craft 1720 Lightweight Hybrid 2007 vs Action Craft 1820 Flats Master 2008 — Common Questions

Which is the larger boat — the Action Craft 1720 Lightweight Hybrid 2007 or the Action Craft 1820 Flats Master 2008?
The Action Craft 1820 Flats Master 2008 is the longer of the two at 18,0 feet overall. The Action Craft 1720 Lightweight Hybrid 2007 comes in at 17,0 feet, making it roughly 1,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Action Craft 1720 Lightweight Hybrid 2007 or the Action Craft 1820 Flats Master 2008?
For trailering, the Action Craft 1720 Lightweight Hybrid 2007 has the edge at 62 lbs dry weight versus 975 lbs for the Action Craft 1820 Flats Master 2008. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Action Craft 1820 Flats Master 2008 is rated to a maximum of 150 hp, giving it the larger power ceiling. The Action Craft 1720 Lightweight Hybrid 2007 tops out at 125 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Action Craft 1720 Lightweight Hybrid 2007 is Coast Guard rated for 5 passengers, while the Action Craft 1820 Flats Master 2008 is certified for 5. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat has the better power-to-weight ratio?
The Action Craft 1720 Lightweight Hybrid 2007 has a better power-to-weight ratio at 1 lbs per hp compared to 7 lbs per hp for the Action Craft 1820 Flats Master 2008. A lower number means quicker acceleration and faster time to plane — the number that actually matters most on short, sporty boats like these.
Which boat is wider, and does it affect trailering?
The Action Craft 1720 Lightweight Hybrid 2007 measures 87" wide, compared to 84" for the Action Craft 1820 Flats Master 2008. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Action Craft 1720 Lightweight Hybrid 2007 or the Action Craft 1820 Flats Master 2008?
The Action Craft 1820 Flats Master 2008 has the bigger tank at 45 gallons, versus 3 gallons on the Action Craft 1720 Lightweight Hybrid 2007. That 42-gallon difference translates to roughly 126–210 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Action Craft 1720 Lightweight Hybrid 2007 and Action Craft 1820 Flats Master 2008 from the same manufacturer?
Yes — both the Action Craft 1720 Lightweight Hybrid 2007 and the Action Craft 1820 Flats Master 2008 are built by Action Craft. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
