Sea Ray 310 Sundancer 2008 vs Sea Ray Express Cruiser 215 1998 — Same Brand, Different Boat

The Sea Ray 310 Sundancer 2008 vs Sea Ray Express Cruiser 215 1998 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 310 Sundancer 2008 measures 33,0 feet overall (2008), giving it roughly 11,4 additional feet of deck space compared to the Sea Ray Express Cruiser 215 1998 at 21,6 feet (1998). Weight tells a clearer story for trailering families: the Sea Ray Express Cruiser 215 1998 tips the scales at 3 699 lbs — 3 685 lbs less than the Sea Ray 310 Sundancer 2008 at 14 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 320 hp, the Sea Ray 310 Sundancer 2008 has a 100-hp advantage over the Sea Ray Express Cruiser 215 1998's 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 2 gal and 5 gal — so range won't be a tiebreaker here.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 310 Sundancer 2008 is rated for 10 passengers, while the Sea Ray Express Cruiser 215 1998 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 310 Sundancer 2008 could be the deciding factor.

Bottom line: Choose the Sea Ray 310 Sundancer 2008 if your priority is putting more people on the water — it handles 10 passengers and at 33,0 ft it has the deck room to back that rating up comfortably. The Sea Ray Express Cruiser 215 1998 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.

Sea Ray 310 Sundancer 2008 vs Sea Ray Express Cruiser 215 1998 — Common Questions

Which is the larger boat — the Sea Ray 310 Sundancer 2008 or the Sea Ray Express Cruiser 215 1998?
The Sea Ray 310 Sundancer 2008 is the longer of the two at 33,0 feet overall. The Sea Ray Express Cruiser 215 1998 comes in at 21,6 feet, making it roughly 11,4 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 310 Sundancer 2008 or the Sea Ray Express Cruiser 215 1998?
For trailering, the Sea Ray 310 Sundancer 2008 has the edge at 14 lbs dry weight versus 3 699 lbs for the Sea Ray Express Cruiser 215 1998. 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 Ray 310 Sundancer 2008 is rated to a maximum of 320 hp, giving it the larger power ceiling. The Sea Ray Express Cruiser 215 1998 tops out at 220 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 Ray 310 Sundancer 2008 is Coast Guard rated for 10 passengers, while the Sea Ray Express Cruiser 215 1998 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 Ray 310 Sundancer 2008 measures 125" wide, compared to 103" for the Sea Ray Express Cruiser 215 1998. 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 310 Sundancer 2008 or the Sea Ray Express Cruiser 215 1998?
The Sea Ray Express Cruiser 215 1998 has the bigger tank at 5 gallons, versus 2 gallons on the Sea Ray 310 Sundancer 2008. That 3-gallon difference translates to roughly 9–15 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 310 Sundancer 2008 and Sea Ray Express Cruiser 215 1998 from the same manufacturer?
Yes — both the Sea Ray 310 Sundancer 2008 and the Sea Ray Express Cruiser 215 1998 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.
