The Beneteau Evasion 25 1977 vs Beneteau Evasion 34 Fin keel 1980 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.
Size is the most obvious dividing line here. The Beneteau Evasion 34 Fin keel 1980 measures 35,1 feet overall (1980), giving it roughly 9,0 additional feet of deck space compared to the Beneteau Evasion 25 1977 at 26,1 feet (1977). Weight tells a clearer story for trailering families: the Beneteau Evasion 34 Fin keel 1980 tips the scales at 12 125 lbs - 6 062 lbs less than the Beneteau Evasion 25 1977 at 6 063 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 50 hp, the Beneteau Evasion 34 Fin keel 1980 has a 25-hp advantage over the Beneteau Evasion 25 1977's 25-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Beneteau Evasion 34 Fin keel 1980 carries 53 gallons versus 13 gallons in the Beneteau Evasion 25 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 Evasion 34 Fin keel 1980 is rated for 10 passengers, while the Beneteau Evasion 25 1977 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau Evasion 34 Fin keel 1980 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau Evasion 34 Fin keel 1980 displaces 12 125 lbs - a 6 062-lb difference over the Beneteau Evasion 25 1977 at 6 063 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 Evasion 34 Fin keel 1980 draws 5,1 ft, compared to 3,1 ft for the Beneteau Evasion 25 1977. That 2,0-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 Evasion 25 1977 uses Sloop rigging. Helm style differs too: the Beneteau Evasion 25 1977 uses a 1 wheel versus a 2 wheels on the Beneteau Evasion 34 Fin keel 1980. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Evasion 34 Fin keel 1980 carries a 50-hp engine against 25 hp on the Beneteau Evasion 25 1977. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.
Hull speed is rated at 7,2 knots for the Beneteau Evasion 34 Fin keel 1980 and 6,0 knots for the Beneteau Evasion 25 1977. For extended cruising, water capacity matters: the Beneteau Evasion 34 Fin keel 1980 carries 79 gallons versus 24 gallons on the Beneteau Evasion 25 1977 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau Evasion 34 Fin keel 1980 is the offshore and bluewater choice - at 12 125 lbs displacement and 35 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau Evasion 25 1977 at 6 063 lbs is the more nimble, accessible option - easier to single-hand and better suited to coastal and inland sailing.
