Starcraft Marine Nexstar 2100 2005 vs Starcraft Marine Sea Star 1915 OB 2006 — Same Brand, Different Boat

The Starcraft Marine Nexstar 2100 2005 vs Starcraft Marine Sea Star 1915 OB 2006 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 Sea Star 1915 OB 2006 measures 19,0 feet overall (2006), giving it roughly 17,0 additional feet of deck space compared to the Starcraft Marine Nexstar 2100 2005 at 2,0 feet (2005). Weight tells a clearer story for trailering families: the Starcraft Marine Nexstar 2100 2005 tips the scales at 2 215 lbs — 1 990 lbs more than the Starcraft Marine Sea Star 1915 OB 2006 at 225 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 Starcraft Marine Nexstar 2100 2005 carries a rated maximum of 300 hp. Engine data for the Starcraft Marine Sea Star 1915 OB 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Starcraft Marine Sea Star 1915 OB 2006 carries 51 gallons versus 5 gallons in the Starcraft Marine Nexstar 2100 2005. 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 Nexstar 2100 2005 is rated for 11 passengers, while the Starcraft Marine Sea Star 1915 OB 2006 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Starcraft Marine Nexstar 2100 2005 could be the deciding factor.

Bottom line: Choose the Starcraft Marine Nexstar 2100 2005 if your priority is putting more people on the water — it handles 11 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The Starcraft Marine Sea Star 1915 OB 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 1 that costs less to run day-to-day.

The Starcraft Marine Sea Star 1915 OB 2006 is the longer of the two at 19,0 feet overall. The Starcraft Marine Nexstar 2100 2005 comes in at 2,0 feet, making it roughly 17,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Starcraft Marine Nexstar 2100 2005 or the Starcraft Marine Sea Star 1915 OB 2006?
For trailering, the Starcraft Marine Sea Star 1915 OB 2006 has the edge at 225 lbs dry weight versus 2 215 lbs for the Starcraft Marine Nexstar 2100 2005. 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.
What is the maximum horsepower rating for these boats?
The Starcraft Marine Nexstar 2100 2005 has a documented max rating of 300 hp. Engine specifications for the Starcraft Marine Sea Star 1915 OB 2006 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Starcraft Marine Nexstar 2100 2005 is Coast Guard rated for 11 passengers, while the Starcraft Marine Sea Star 1915 OB 2006 is certified for 1. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Starcraft Marine Nexstar 2100 2005 and Starcraft Marine Sea Star 1915 OB 2006 share an 102 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Starcraft Marine Nexstar 2100 2005 or the Starcraft Marine Sea Star 1915 OB 2006?
The Starcraft Marine Sea Star 1915 OB 2006 has the bigger tank at 51 gallons, versus 5 gallons on the Starcraft Marine Nexstar 2100 2005. That 46-gallon difference translates to roughly 138–230 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Starcraft Marine Nexstar 2100 2005 and Starcraft Marine Sea Star 1915 OB 2006 from the same manufacturer?
Yes — both the Starcraft Marine Nexstar 2100 2005 and the Starcraft Marine Sea Star 1915 OB 2006 are built by Starcraft Marine. 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.
