Sea Ray 340 Sundancer 2006 vs Sea Ray Sundancer 370 Outboard 2023 — Same Brand, Different Boat

The Sea Ray 340 Sundancer 2006 vs Sea Ray Sundancer 370 Outboard 2023 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.

On paper these two are close siblings in the size department — Sea Ray 340 Sundancer 2006 at 37,0 ft versus Sea Ray Sundancer 370 Outboard 2023 at 39,9 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 370 Outboard 2023 tips the scales at 21 008 lbs — 20 862 lbs less than the Sea Ray 340 Sundancer 2006 at 146 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 375 hp, the Sea Ray 340 Sundancer 2006 has a 75-hp advantage over the Sea Ray Sundancer 370 Outboard 2023's 300-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray 340 Sundancer 2006 carries 225 gallons versus 25 gallons in the Sea Ray Sundancer 370 Outboard 2023. 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 Sea Ray Sundancer 370 Outboard 2023 is rated for 12 passengers, while the Sea Ray 340 Sundancer 2006 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundancer 370 Outboard 2023 could be the deciding factor.

Bottom line: Choose the Sea Ray Sundancer 370 Outboard 2023 if your priority is putting more people on the water — it handles 12 passengers and at 39,9 ft it has the deck room to back that rating up comfortably. The Sea Ray 340 Sundancer 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.

Sea Ray 340 Sundancer 2006 vs Sea Ray Sundancer 370 Outboard 2023 — Common Questions

Which is the larger boat — the Sea Ray 340 Sundancer 2006 or the Sea Ray Sundancer 370 Outboard 2023?
The Sea Ray Sundancer 370 Outboard 2023 is the longer of the two at 39,9 feet overall. The Sea Ray 340 Sundancer 2006 comes in at 37,0 feet, making it roughly 2,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 340 Sundancer 2006 or the Sea Ray Sundancer 370 Outboard 2023?
For trailering, the Sea Ray 340 Sundancer 2006 has the edge at 146 lbs dry weight versus 21 008 lbs for the Sea Ray Sundancer 370 Outboard 2023. 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 340 Sundancer 2006 is rated to a maximum of 375 hp, giving it the larger power ceiling. The Sea Ray Sundancer 370 Outboard 2023 tops out at 300 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 340 Sundancer 2006 is Coast Guard rated for 11 passengers, while the Sea Ray Sundancer 370 Outboard 2023 is certified for 12. 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.
Do these boats require an oversize trailer permit to tow on US highways?
Both the Sea Ray 340 Sundancer 2006 and Sea Ray Sundancer 370 Outboard 2023 share an 12 ft. 0 in. (3.66 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary. Always check the rules for your state and any states you'll be passing through before your first long haul.
Which boat has the larger fuel tank — the Sea Ray 340 Sundancer 2006 or the Sea Ray Sundancer 370 Outboard 2023?
The Sea Ray 340 Sundancer 2006 has the bigger tank at 225 gallons, versus 25 gallons on the Sea Ray Sundancer 370 Outboard 2023. That 200-gallon difference translates to roughly 600–1000 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Sea Ray 340 Sundancer 2006 and Sea Ray Sundancer 370 Outboard 2023 from the same manufacturer?
Yes — both the Sea Ray 340 Sundancer 2006 and the Sea Ray Sundancer 370 Outboard 2023 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.
