The Beneteau 34.7 Deep draft 2005 vs Beneteau First 310 1990 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 310 1990 at 31,1 ft. Weight tells a clearer story for trailering families: the Beneteau 34.7 Deep draft 2005 tips the scales at 9 965 lbs — 1 808 lbs more than the Beneteau First 310 1990 at 8 157 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 310 1990. 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 17 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 First 310 1990 caps at 9. 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.
Both boats sit in a similar displacement bracket — 9 965 lbs for the Beneteau 34.7 Deep draft 2005 and 8 157 lbs for the Beneteau First 310 1990. 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 6,0 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
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 First 310 1990.

Hull speed is rated at 7,2 knots for the Beneteau First 310 1990 and 7,2 knots for the Beneteau 34.7 Deep draft 2005. For extended cruising, water capacity matters: the Beneteau First 310 1990 carries 45 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 34.7 Deep draft 2005 at 34,0 ft offers more living space, greater range, and a more substantial offshore capability. The Beneteau First 310 1990 at 31,1 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.
