Detailed Evaluation & Buyer Recommendation
Sealine S390 2021 vs Sealine SC38 2007 — Same Brand, Different Boat
The Sealine S390 2021 vs Sealine SC38 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.
The power gap is worth calling out. Rated to 380 hp, the Sealine S390 2021 has a 70-hp advantage over the Sealine SC38 2007's 310-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sealine S390 2021 carries 198 gallons versus 179 gallons in the Sealine SC38 2007. 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 Sealine S390 2021 is rated for 12 passengers, while the Sealine SC38 2007 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine S390 2021 could be the deciding factor.
Bottom line: Choose the Sealine S390 2021 if your priority is putting more people on the water — it handles 12 passengers and at 39,4 ft it has the deck room to back that rating up comfortably. The Sealine SC38 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
