Sea Boss 190 Center Console 2004 vs Sea Boss 21 Bay 2007 — Same Brand, Different Boat

The Sea Boss 190 Center Console 2004 vs Sea Boss 21 Bay 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 200 hp, the Sea Boss 21 Bay 2007 has a 50-hp advantage over the Sea Boss 190 Center Console 2004's 150-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 53 gal and 54 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Boss 21 Bay 2007 is rated for 6 passengers, while the Sea Boss 190 Center Console 2004 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Boss 21 Bay 2007 could be the deciding factor.

Bottom line: Choose the Sea Boss 21 Bay 2007 if your priority is putting more people on the water — it handles 6 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Sea Boss 190 Center Console 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.

Sea Boss 190 Center Console 2004 vs Sea Boss 21 Bay 2007 — Common Questions

Which is easier to trailer — the Sea Boss 190 Center Console 2004 or the Sea Boss 21 Bay 2007?
For trailering, the Sea Boss 21 Bay 2007 has the edge at 16 lbs dry weight versus 175 lbs for the Sea Boss 190 Center Console 2004. 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 Sea Boss 21 Bay 2007 is rated to a maximum of 200 hp, giving it the larger power ceiling. The Sea Boss 190 Center Console 2004 tops out at 150 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 Sea Boss 190 Center Console 2004 is Coast Guard rated for 5 passengers, while the Sea Boss 21 Bay 2007 is certified for 6. 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 Sea Boss 190 Center Console 2004 measures 96" wide, compared to 94" for the Sea Boss 21 Bay 2007. 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.
How do the fuel tanks compare on the Sea Boss 190 Center Console 2004 and Sea Boss 21 Bay 2007?
Both boats carry similar fuel loads — 53 gallons and 54 gallons respectively. Range will depend heavily on motor choice, throttle usage, and whether you're on flat lake water or coastal chop.
Are the Sea Boss 190 Center Console 2004 and Sea Boss 21 Bay 2007 from the same manufacturer?
Yes — both the Sea Boss 190 Center Console 2004 and the Sea Boss 21 Bay 2007 are built by Sea Boss. 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.
