The Beneteau Oceanis 320 1987 vs Beneteau Oceanis Clipper 323 2003 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 — Beneteau Oceanis 320 1987 at 31,6 ft versus Beneteau Oceanis Clipper 323 2003 at 32,1 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis Clipper 323 2003 tips the scales at 9 326 lbs — 508 lbs less than the Beneteau Oceanis 320 1987 at 8 818 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.
Both boats share a closely matched power ceiling — 18 hp for the Beneteau Oceanis 320 1987 and 21 hp for the Beneteau Oceanis Clipper 323 2003. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Beneteau Oceanis Clipper 323 2003 carries 20 gallons versus 13 gallons in the Beneteau Oceanis 320 1987. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 9 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.
Both boats sit in a similar displacement bracket — 8 818 lbs for the Beneteau Oceanis 320 1987 and 9 326 lbs for the Beneteau Oceanis Clipper 323 2003. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.
Both boats draw a similar depth — 4,7 ft and 5,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau Oceanis 320 1987 uses Sloop rigging. Helm style differs too: the Beneteau Oceanis 320 1987 uses a 1 tiller versus a 1 wheel on the Beneteau Oceanis Clipper 323 2003. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones.
Hull speed is rated at 7,2 knots for the Beneteau Oceanis Clipper 323 2003 and 7,1 knots for the Beneteau Oceanis 320 1987.
Bottom line: The Beneteau Oceanis 320 1987 and Beneteau Oceanis Clipper 323 2003 are closely matched on paper. A sea trial on both in representative conditions is the only reliable way to find which one suits your sailing style, home port, and intended cruising ground.
