The Starcraft Marine Bay 170 2013 vs Starcraft Marine Mariner 2100 Center Console 2007 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.

Size is the most obvious dividing line here. The Starcraft Marine Bay 170 2013 measures 16,5 feet overall (2013), giving it roughly 14,5 additional feet of deck space compared to the Starcraft Marine Mariner 2100 Center Console 2007 at 2,0 feet (2007). Weight tells a clearer story for trailering families: the Starcraft Marine Mariner 2100 Center Console 2007 tips the scales at 1 525 lbs — 464 lbs less than the Starcraft Marine Bay 170 2013 at 1 061 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 250 hp, the Starcraft Marine Mariner 2100 Center Console 2007 has a 135-hp advantage over the Starcraft Marine Bay 170 2013'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 Starcraft Marine Mariner 2100 Center Console 2007 carries 32 gallons versus 19 gallons in the Starcraft Marine Bay 170 2013. 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 Starcraft Marine Mariner 2100 Center Console 2007 is rated for 10 passengers, while the Starcraft Marine Bay 170 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Mariner 2100 Center Console 2007 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Starcraft Marine Mariner 2100 Center Console 2007 comes in at 6 lbs per hp versus 9 lbs per hp for the Starcraft Marine Bay 170 2013. 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.
