When two boats share the same hull type — in this case both the SeaArk Outlaw 170 2008 and the SeaArk ProCat 240 2008 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 ProCat 240 2008 measures 24,0 feet overall (2008), giving it roughly 7,0 additional feet of deck space compared to the SeaArk Outlaw 170 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the SeaArk ProCat 240 2008 tips the scales at 172 lbs — 164 lbs less than the SeaArk Outlaw 170 2008 at 8 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 225 hp, the SeaArk ProCat 240 2008 has a 150-hp advantage over the SeaArk Outlaw 170 2008's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The SeaArk ProCat 240 2008 is rated for 10 passengers, while the SeaArk Outlaw 170 2008 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk ProCat 240 2008 could be the deciding factor.
Bottom line: Choose the SeaArk ProCat 240 2008 if your priority is putting more people on the water — it handles 10 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The SeaArk Outlaw 170 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
