Sea Ray 340 Sundancer 2005 vs Sea Ray Aft Cabin 370 1997 — Same Brand, Different Boat

The Sea Ray 340 Sundancer 2005 vs Sea Ray Aft Cabin 370 1997 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 2005 at 37,0 ft versus Sea Ray Aft Cabin 370 1997 at 38,2 ft. Weight tells a clearer story for trailering families: the Sea Ray Aft Cabin 370 1997 tips the scales at 24 000 lbs — 23 854 lbs less than the Sea Ray 340 Sundancer 2005 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 Sea Ray Aft Cabin 370 1997 tops out at 370 hp. Engine specs for the Sea Ray 340 Sundancer 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 340 Sundancer 2005 carries 225 gallons versus 3 gallons in the Sea Ray Aft Cabin 370 1997. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 11 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 340 Sundancer 2005 and Sea Ray Aft Cabin 370 1997 are closely matched on the specs that matter most. Test-ride both on the water you actually use, check current dealer pricing, and factor in long-term service access before you sign.
