Q: Which is easier to trailer — the Crestliner Canadian 18 SC 2004 or the Crestliner Sportfish 1850 Sterndrive 2006?

For trailering, the Crestliner Canadian 18 SC 2004 has the edge at 81 lbs dry weight versus 2 105 lbs for the Crestliner Sportfish 1850 Sterndrive 2006.

Q: How many people can each boat hold?

The Crestliner Canadian 18 SC 2004 is Coast Guard rated for 5 passengers, while the Crestliner Sportfish 1850 Sterndrive 2006 is certified for 7. 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.

The Crestliner Sportfish 1850 Sterndrive 2006 measures 95" wide, compared to 79" for the Crestliner Canadian 18 SC 2004.

The Crestliner Sportfish 1850 Sterndrive 2006 has the bigger tank at 39 gallons, versus 17 gallons on the Crestliner Canadian 18 SC 2004. That 22-gallon difference translates to roughly 66–110 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Detailed Evaluation & Buyer Recommendation

Crestliner Canadian 18 SC 2004 vs Crestliner Sportfish 1850 Sterndrive 2006 — Same Brand, Different Boat

The Crestliner Canadian 18 SC 2004 vs Crestliner Sportfish 1850 Sterndrive 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.

The Crestliner Canadian 18 SC 2004 carries a rated maximum of 6 hp. Engine data for the Crestliner Sportfish 1850 Sterndrive 2006 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Crestliner Sportfish 1850 Sterndrive 2006 carries 39 gallons versus 17 gallons in the Crestliner Canadian 18 SC 2004. 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 1850 Sterndrive 2006 is rated for 7 passengers, while the Crestliner Canadian 18 SC 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Crestliner Sportfish 1850 Sterndrive 2006 could be the deciding factor.

Bottom line: Choose the Crestliner Sportfish 1850 Sterndrive 2006 if your priority is putting more people on the water — it handles 7 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Crestliner Canadian 18 SC 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
