Beneteau Oceanis 311 1997 vs Beneteau Oceanis 34.1 2014 — Same Brand, Different Boat

The Beneteau Oceanis 311 1997 vs Beneteau Oceanis 34.1 2014 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 311 1997 at 32,4 ft versus Beneteau Oceanis 34.1 2014 at 33,9 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 34.1 2014 tips the scales at 12 389 lbs — 4 342 lbs less than the Beneteau Oceanis 311 1997 at 8 047 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 Beneteau Oceanis 34.1 2014 tops out at 29 hp. Engine specs for the Beneteau Oceanis 311 1997 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Beneteau Oceanis 34.1 2014 carries 34 gallons versus 19 gallons in the Beneteau Oceanis 311 1997. 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 34.1 2014 is rated for 10 passengers, while the Beneteau Oceanis 311 1997 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Oceanis 34.1 2014 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 34.1 2014 displaces 12 389 lbs — a 4 342-lb difference over the Beneteau Oceanis 311 1997 at 8 047 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Beneteau Oceanis 34.1 2014 draws 6,0 ft, compared to 4,1 ft for the Beneteau Oceanis 311 1997. That 1,9-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 Oceanis 311 1997 uses Sloop rigging. The Beneteau Oceanis 34.1 2014 has a documented auxiliary engine of 29 hp.

For extended cruising, water capacity matters: the Beneteau Oceanis 34.1 2014 carries 77 gallons versus 53 gallons on the Beneteau Oceanis 311 1997 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Beneteau Oceanis 34.1 2014 is the offshore and bluewater choice — at 12 389 lbs displacement and 34 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Oceanis 311 1997 at 8 047 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.

Beneteau Oceanis 311 1997 vs Beneteau Oceanis 34.1 2014 — Common Questions

Which is the larger boat — the Beneteau Oceanis 311 1997 or the Beneteau Oceanis 34.1 2014?
The Beneteau Oceanis 34.1 2014 is the longer of the two at 33,9 feet overall. The Beneteau Oceanis 311 1997 comes in at 32,4 feet, making it roughly 1,5 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Beneteau Oceanis 311 1997 or the Beneteau Oceanis 34.1 2014?
For trailering, the Beneteau Oceanis 311 1997 has the edge at 8 047 lbs dry weight versus 12 389 lbs for the Beneteau Oceanis 34.1 2014. 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.
What is the maximum horsepower rating for these boats?
The Beneteau Oceanis 34.1 2014 has a documented max rating of 29 hp. Engine specifications for the Beneteau Oceanis 311 1997 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Beneteau Oceanis 311 1997 is Coast Guard rated for 9 passengers, while the Beneteau Oceanis 34.1 2014 is certified for 10. 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 Oceanis 311 1997 or the Beneteau Oceanis 34.1 2014?
The Beneteau Oceanis 34.1 2014 has the deeper draft at 6,0 ft, versus 4,1 ft for the Beneteau Oceanis 311 1997. 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 Oceanis 311 1997 or the Beneteau Oceanis 34.1 2014 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Beneteau Oceanis 34.1 2014 at 12 389 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 311 1997 at 8 047 lbs will typically be livelier and more responsive in lighter conditions.
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 34.1 2014 carries 77 gallons of fresh water compared to 53 gallons on the Beneteau Oceanis 311 1997 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Beneteau Oceanis 34.1 2014 measures 143" wide, compared to 128" for the Beneteau Oceanis 311 1997. 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 Oceanis 311 1997 or the Beneteau Oceanis 34.1 2014?
The Beneteau Oceanis 34.1 2014 has the bigger tank at 34 gallons, versus 19 gallons on the Beneteau Oceanis 311 1997. That 15-gallon difference translates to roughly 47–78 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Beneteau Oceanis 311 1997 and Beneteau Oceanis 34.1 2014 from the same manufacturer?
Yes — both the Beneteau Oceanis 311 1997 and the Beneteau Oceanis 34.1 2014 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.
