Both the Stabicraft 389 Frontier 2011 and the Stabicraft 859 Supercab Weekender 2011 are pontoon 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 Stabicraft 859 Supercab Weekender 2011 measures 30,0 feet overall (2011), giving it roughly 16,1 additional feet of deck space compared to the Stabicraft 389 Frontier 2011 at 13,9 feet (2011). Weight tells a clearer story for trailering families: the Stabicraft 859 Supercab Weekender 2011 tips the scales at 8 708 lbs - 7 826 lbs less than the Stabicraft 389 Frontier 2011 at 882 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 450 hp, the Stabicraft 859 Supercab Weekender 2011 has a 410-hp advantage over the Stabicraft 389 Frontier 2011's 40-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 Stabicraft 859 Supercab Weekender 2011 is rated for 12 passengers, while the Stabicraft 389 Frontier 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Stabicraft 859 Supercab Weekender 2011 could be the deciding factor.
Bottom line: Choose the Stabicraft 859 Supercab Weekender 2011 if your priority is putting more people on the water - it handles 12 passengers and at 30,0 ft it has the deck room to back that rating up comfortably. The Stabicraft 389 Frontier 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
