Starcraft Marine Nexstar 2100 I/O 2006 vs Starcraft Marine Sea Star 2000 OB 2006 — Same Brand, Different Boat

The Starcraft Marine Nexstar 2100 I/O 2006 vs Starcraft Marine Sea Star 2000 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 Nexstar 2100 I/O 2006 measures 21,0 feet overall (2006), giving it roughly 19,0 additional feet of deck space compared to the Starcraft Marine Sea Star 2000 OB 2006 at 2,0 feet (2006). Weight tells a clearer story for trailering families: the Starcraft Marine Sea Star 2000 OB 2006 tips the scales at 2 315 lbs — 2 292 lbs less than the Starcraft Marine Nexstar 2100 I/O 2006 at 23 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 I/O 2006 carries a rated maximum of 6 hp. Engine data for the Starcraft Marine Sea Star 2000 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 2000 OB 2006 carries 51 gallons versus 45 gallons in the Starcraft Marine Nexstar 2100 I/O 2006. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 12 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Starcraft Marine Nexstar 2100 I/O 2006 at 21,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Starcraft Marine Sea Star 2000 OB 2006 at 2,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.

Starcraft Marine Nexstar 2100 I/O 2006 vs Starcraft Marine Sea Star 2000 OB 2006 — Common Questions

Which is the larger boat — the Starcraft Marine Nexstar 2100 I/O 2006 or the Starcraft Marine Sea Star 2000 OB 2006?
The Starcraft Marine Nexstar 2100 I/O 2006 is the longer of the two at 21,0 feet overall. The Starcraft Marine Sea Star 2000 OB 2006 comes in at 2,0 feet, making it roughly 19,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Starcraft Marine Nexstar 2100 I/O 2006 or the Starcraft Marine Sea Star 2000 OB 2006?
For trailering, the Starcraft Marine Nexstar 2100 I/O 2006 has the edge at 23 lbs dry weight versus 2 315 lbs for the Starcraft Marine Sea Star 2000 OB 2006. 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 I/O 2006 has a documented max rating of 6 hp. Engine specifications for the Starcraft Marine Sea Star 2000 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 I/O 2006 is Coast Guard rated for 12 passengers, while the Starcraft Marine Sea Star 2000 OB 2006 is certified for 12. 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 I/O 2006 and Starcraft Marine Sea Star 2000 OB 2006 share an 102 in. (259 cm) 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 I/O 2006 or the Starcraft Marine Sea Star 2000 OB 2006?
The Starcraft Marine Sea Star 2000 OB 2006 has the bigger tank at 51 gallons, versus 45 gallons on the Starcraft Marine Nexstar 2100 I/O 2006. That 6-gallon difference translates to roughly 18–30 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Starcraft Marine Nexstar 2100 I/O 2006 and Starcraft Marine Sea Star 2000 OB 2006 from the same manufacturer?
Yes — both the Starcraft Marine Nexstar 2100 I/O 2006 and the Starcraft Marine Sea Star 2000 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.
