The Beneteau 34.7 Deep draft 2005 vs Beneteau Idylle 8.80 1982 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 5,9 additional feet of deck space compared to the Beneteau Idylle 8.80 1982 at 28,1 feet (1982). Weight tells a clearer story for trailering families: the Beneteau 34.7 Deep draft 2005 tips the scales at 9 965 lbs — 2 580 lbs more than the Beneteau Idylle 8.80 1982 at 7 385 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 30 hp for the Beneteau Idylle 8.80 1982. 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. Both carry nearly identical fuel loads — 20 gal and 21 gal — so range won't be a tiebreaker here.
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 Idylle 8.80 1982 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 2 580-lb difference over the Beneteau Idylle 8.80 1982 at 7 385 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 4,1 ft for the Beneteau Idylle 8.80 1982. That 2,6-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 Idylle 8.80 1982. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Idylle 8.80 1982 carries a 30-hp engine against 21 hp on the Beneteau 34.7 Deep draft 2005. 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 34.7 Deep draft 2005 and 6,6 knots for the Beneteau Idylle 8.80 1982.
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 Idylle 8.80 1982 at 7 385 lbs is the more nimble, accessible option — easier to single-hand and better suited to coastal and inland sailing.
