The Beneteau 34.7 Deep draft 2005 vs Beneteau R/C 27 1978 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 34.7 Deep draft 2005 measures 34,0 feet overall (2005), giving it roughly 6,3 additional feet of deck space compared to the Beneteau R/C 27 1978 at 27,7 feet (1978). Weight tells a clearer story for trailering families: the Beneteau 34.7 Deep draft 2005 tips the scales at 9 965 lbs — 4 674 lbs more than the Beneteau R/C 27 1978 at 5 291 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 — 21 hp for the Beneteau 34.7 Deep draft 2005 and 16 hp for the Beneteau R/C 27 1978. 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 34.7 Deep draft 2005 carries 20 gallons versus 7 gallons in the Beneteau R/C 27 1978. 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 34.7 Deep draft 2005 is rated for 10 passengers, while the Beneteau R/C 27 1978 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau 34.7 Deep draft 2005 could be the deciding factor.
Displacement is where these two sailboats genuinely part ways. The Beneteau 34.7 Deep draft 2005 displaces 9 965 lbs — a 4 674-lb difference over the Beneteau R/C 27 1978 at 5 291 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 34.7 Deep draft 2005 draws 6,7 ft, compared to 5,1 ft for the Beneteau R/C 27 1978. That 1,6-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 34.7 Deep draft 2005 uses Sloop rigging. Helm style differs too: the Beneteau 34.7 Deep draft 2005 uses a 1 wheel versus a 1 tiller on the Beneteau R/C 27 1978. 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 34.7 Deep draft 2005 and 6,2 knots for the Beneteau R/C 27 1978.
Bottom line: The Beneteau 34.7 Deep draft 2005 is the offshore and bluewater choice — at 9 965 lbs displacement and 34 ft it has the load capacity, range, and seakeeping for extended passages. The Beneteau R/C 27 1978 at 5 291 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
