The Beneteau 34.7 Deep draft 2005 vs Beneteau First 345 1983 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 34.7 Deep draft 2005 at 34,0 ft versus Beneteau First 345 1983 at 36,1 ft. Weight tells a clearer story for trailering families: the Beneteau First 345 1983 tips the scales at 11 244 lbs — 1 279 lbs less than the Beneteau 34.7 Deep draft 2005 at 9 965 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 18 hp for the Beneteau First 345 1983. 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 23 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Beneteau First 345 1983 is rated for 11 passengers, while the Beneteau 34.7 Deep draft 2005 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Beneteau First 345 1983 could be the deciding factor.
Both boats sit in a similar displacement bracket — 9 965 lbs for the Beneteau 34.7 Deep draft 2005 and 11 244 lbs for the Beneteau First 345 1983. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.
Both boats draw a similar depth — 6,7 ft and 6,2 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau 34.7 Deep draft 2005 is rigged as a Sloop while the Beneteau First 345 1983 carries fractional_rig_sloop rigging — a meaningful difference in sail handling complexity, upwind performance, and the size of crew you'll need to work the boat comfortably. Helm style differs too: the Beneteau 34.7 Deep draft 2005 uses a 1 wheel versus a 1 tiller on the Beneteau First 345 1983. 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 First 345 1983 and 7,2 knots for the Beneteau 34.7 Deep draft 2005. For extended cruising, water capacity matters: the Beneteau First 345 1983 carries 106 gallons versus 26 gallons on the Beneteau 34.7 Deep draft 2005 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 345 1983 at 36,1 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau 34.7 Deep draft 2005 at 34,0 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
