Sea Ray 185 Sport 2005 vs Sea Ray 680 Sun Sport 2005 — Same Brand, Different Boat

The Sea Ray 185 Sport 2005 vs Sea Ray 680 Sun Sport 2005 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 Sea Ray 185 Sport 2005 measures 18,0 feet overall (2005), giving it roughly 11,0 additional feet of deck space compared to the Sea Ray 680 Sun Sport 2005 at 7,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray 185 Sport 2005 tips the scales at 265 lbs — 190 lbs more than the Sea Ray 680 Sun Sport 2005 at 75 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.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 680 Sun Sport 2005 is rated for 21 passengers, while the Sea Ray 185 Sport 2005 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 680 Sun Sport 2005 could be the deciding factor.

Bottom line: Choose the Sea Ray 680 Sun Sport 2005 if your priority is putting more people on the water — it handles 21 passengers and at 7,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 185 Sport 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Sea Ray 185 Sport 2005 vs Sea Ray 680 Sun Sport 2005 — Common Questions

Which is the larger boat — the Sea Ray 185 Sport 2005 or the Sea Ray 680 Sun Sport 2005?
The Sea Ray 185 Sport 2005 is the longer of the two at 18,0 feet overall. The Sea Ray 680 Sun Sport 2005 comes in at 7,0 feet, making it roughly 11,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

For trailering, the Sea Ray 680 Sun Sport 2005 has the edge at 75 lbs dry weight versus 265 lbs for the Sea Ray 185 Sport 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows.

How many people can each boat hold?
The Sea Ray 185 Sport 2005 is Coast Guard rated for 7 passengers, while the Sea Ray 680 Sun Sport 2005 is certified for 21. 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 Ray 680 Sun Sport 2005 measures 222" wide, compared to 76" for the Sea Ray 185 Sport 2005. 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 Sea Ray 185 Sport 2005 or the Sea Ray 680 Sun Sport 2005?
The Sea Ray 185 Sport 2005 has the bigger tank at 26 gallons, versus 1 gallons on the Sea Ray 680 Sun Sport 2005. That 25-gallon difference translates to roughly 75–125 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Sea Ray 185 Sport 2005 and the Sea Ray 680 Sun Sport 2005 are built by Sea Ray. 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.
