Beneteau First 30 Fin keel 1977 vs Beneteau Oceanis 320 1987 — Same Brand, Different Boat

The Beneteau First 30 Fin keel 1977 vs Beneteau Oceanis 320 1987 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 First 30 Fin keel 1977 at 29,5 ft versus Beneteau Oceanis 320 1987 at 31,6 ft. Weight tells a clearer story for trailering families: the Beneteau First 30 Fin keel 1977 tips the scales at 8 995 lbs — 177 lbs more 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 — 20 hp for the Beneteau First 30 Fin keel 1977 and 18 hp for the Beneteau Oceanis 320 1987. 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 320 1987 carries 13 gallons versus 8 gallons in the Beneteau First 30 Fin keel 1977. 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 Beneteau Oceanis 320 1987 is rated for 9 passengers, while the Beneteau First 30 Fin keel 1977 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 320 1987 could be the deciding factor.

Both boats sit in a similar displacement bracket — 8 995 lbs for the Beneteau First 30 Fin keel 1977 and 8 818 lbs for the Beneteau Oceanis 320 1987. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau First 30 Fin keel 1977 draws 5,8 ft, compared to 4,7 ft for the Beneteau Oceanis 320 1987. That 1,1-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

The Beneteau First 30 Fin keel 1977 uses Sloop rigging.

Hull speed is rated at 7,1 knots for the Beneteau Oceanis 320 1987 and 6,8 knots for the Beneteau First 30 Fin keel 1977. For extended cruising, water capacity matters: the Beneteau Oceanis 320 1987 carries 40 gallons versus 24 gallons on the Beneteau First 30 Fin keel 1977 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau Oceanis 320 1987 at 31,6 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau First 30 Fin keel 1977 at 29,5 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.

Beneteau First 30 Fin keel 1977 vs Beneteau Oceanis 320 1987 — Common Questions

Which is the larger boat — the Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987?
The Beneteau Oceanis 320 1987 is the longer of the two at 31,6 feet overall. The Beneteau First 30 Fin keel 1977 comes in at 29,5 feet, making it roughly 2,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987?
For trailering, the Beneteau Oceanis 320 1987 has the edge at 8 818 lbs dry weight versus 8 995 lbs for the Beneteau First 30 Fin keel 1977. 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.
How many people can each boat hold?
The Beneteau First 30 Fin keel 1977 is Coast Guard rated for 8 passengers, while the Beneteau Oceanis 320 1987 is certified for 9. 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 has the deeper draft — the Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987?
The Beneteau First 30 Fin keel 1977 has the deeper draft at 5,8 ft, versus 4,7 ft for the Beneteau Oceanis 320 1987. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau First 30 Fin keel 1977 at 8 995 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Beneteau Oceanis 320 1987 at 8 818 lbs will typically be livelier and more responsive in lighter conditions.
Which is the faster sailboat — the Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987?
Based on rated hull speed, the Beneteau Oceanis 320 1987 has an edge at 7,1 knots versus 6,8 knots for the Beneteau First 30 Fin keel 1977. Keep in mind that actual sailing speed depends heavily on wind conditions, sail trim, bottom condition, and skipper experience — hull speed is a theoretical maximum, not a guarantee.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Beneteau Oceanis 320 1987 carries 40 gallons of fresh water compared to 24 gallons on the Beneteau First 30 Fin keel 1977 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Beneteau Oceanis 320 1987 measures 130" wide, compared to 114" for the Beneteau First 30 Fin keel 1977. 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 Beneteau First 30 Fin keel 1977 or the Beneteau Oceanis 320 1987?
The Beneteau Oceanis 320 1987 has the bigger tank at 13 gallons, versus 8 gallons on the Beneteau First 30 Fin keel 1977. That 5-gallon difference translates to roughly 15–26 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau First 30 Fin keel 1977 and Beneteau Oceanis 320 1987 from the same manufacturer?
Yes — both the Beneteau First 30 Fin keel 1977 and the Beneteau Oceanis 320 1987 are built by Beneteau. 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.
