When two boats share the same hull type — in this case both the SeaArk DuckHawk 2072SS 2008 and the SeaArk Forecast 170C 2010 are modified vee designs with aluminum 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?

Size is the most obvious dividing line here. The SeaArk Forecast 170C 2010 measures 17,0 feet overall (2010), giving it roughly 15,0 additional feet of deck space compared to the SeaArk DuckHawk 2072SS 2008 at 2,0 feet (2008). Weight tells a clearer story for trailering families: the SeaArk Forecast 170C 2010 tips the scales at 775 lbs — 694 lbs less than the SeaArk DuckHawk 2072SS 2008 at 81 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 — 90 hp for the SeaArk DuckHawk 2072SS 2008 and 75 hp for the SeaArk Forecast 170C 2010. 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 SeaArk DuckHawk 2072SS 2008 is rated for 13 passengers, while the SeaArk Forecast 170C 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk DuckHawk 2072SS 2008 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The SeaArk DuckHawk 2072SS 2008 comes in at 1 lbs per hp versus 10 lbs per hp for the SeaArk Forecast 170C 2010. 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.
