Crestliner Sportfish 2150 O/B 2005 vs Crestliner TC 17 2011 — Same Brand, Different Boat

The Crestliner Sportfish 2150 O/B 2005 vs Crestliner TC 17 2011 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 Crestliner Sportfish 2150 O/B 2005 measures 21,0 feet overall (2005), giving it roughly 4,0 additional feet of deck space compared to the Crestliner TC 17 2011 at 17,0 feet (2011). Weight tells a clearer story for trailering families: the Crestliner TC 17 2011 tips the scales at 966 lbs — 761 lbs less than the Crestliner Sportfish 2150 O/B 2005 at 205 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 Crestliner Sportfish 2150 O/B 2005 has a 175-hp advantage over the Crestliner TC 17 2011's 75-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Crestliner Sportfish 2150 O/B 2005 carries 77 gallons versus 12 gallons in the Crestliner TC 17 2011. 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 Crestliner Sportfish 2150 O/B 2005 is rated for 8 passengers, while the Crestliner TC 17 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportfish 2150 O/B 2005 could be the deciding factor.

Bottom line: Choose the Crestliner Sportfish 2150 O/B 2005 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Crestliner TC 17 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.

Crestliner Sportfish 2150 O/B 2005 vs Crestliner TC 17 2011 — Common Questions

Which is the larger boat — the Crestliner Sportfish 2150 O/B 2005 or the Crestliner TC 17 2011?
The Crestliner Sportfish 2150 O/B 2005 is the longer of the two at 21,0 feet overall. The Crestliner TC 17 2011 comes in at 17,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Crestliner Sportfish 2150 O/B 2005 or the Crestliner TC 17 2011?
For trailering, the Crestliner Sportfish 2150 O/B 2005 has the edge at 205 lbs dry weight versus 966 lbs for the Crestliner TC 17 2011. 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.
Which boat can handle a bigger outboard?
The Crestliner Sportfish 2150 O/B 2005 is rated to a maximum of 250 hp, giving it the larger power ceiling. The Crestliner TC 17 2011 tops out at 75 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Crestliner Sportfish 2150 O/B 2005 is Coast Guard rated for 8 passengers, while the Crestliner TC 17 2011 is certified for 4. 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.
Which boat is wider, and does it affect trailering?
The Crestliner Sportfish 2150 O/B 2005 measures 102" wide, compared to 85" for the Crestliner TC 17 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Crestliner Sportfish 2150 O/B 2005 or the Crestliner TC 17 2011?
The Crestliner Sportfish 2150 O/B 2005 has the bigger tank at 77 gallons, versus 12 gallons on the Crestliner TC 17 2011. That 65-gallon difference translates to roughly 195–325 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Crestliner Sportfish 2150 O/B 2005 and Crestliner TC 17 2011 from the same manufacturer?
Yes — both the Crestliner Sportfish 2150 O/B 2005 and the Crestliner TC 17 2011 are built by Crestliner. 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.
