The Beneteau First 29 Deep draft 1983 vs Beneteau Oceanis 31 2007 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 First 29 Deep draft 1983 at 29,6 ft versus Beneteau Oceanis 31 2007 at 31,8 ft. Weight tells a clearer story for trailering families: the Beneteau Oceanis 31 2007 tips the scales at 10 692 lbs — 4 078 lbs less than the Beneteau First 29 Deep draft 1983 at 6 614 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 — 9 hp for the Beneteau First 29 Deep draft 1983 and 21 hp for the Beneteau Oceanis 31 2007. 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 Oceanis 31 2007 carries 34 gallons versus 7 gallons in the Beneteau First 29 Deep draft 1983. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 9 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Displacement is where these two sailboats genuinely part ways. The Beneteau Oceanis 31 2007 displaces 10 692 lbs — a 4 078-lb difference over the Beneteau First 29 Deep draft 1983 at 6 614 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.

Both boats draw a similar depth — 5,6 ft and 5,1 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

The Beneteau First 29 Deep draft 1983 is rigged as a Sloop while the Beneteau Oceanis 31 2007 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 First 29 Deep draft 1983 uses a 1 tiller versus a 1 wheel on the Beneteau Oceanis 31 2007. Wheel helms give better leverage and visibility on larger boats; tillers offer direct feedback and simplicity on smaller ones. For auxiliary power the Beneteau Oceanis 31 2007 carries a 21-hp engine against 9 hp on the Beneteau First 29 Deep draft 1983. 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 Oceanis 31 2007 and 6,7 knots for the Beneteau First 29 Deep draft 1983. For extended cruising, water capacity matters: the Beneteau Oceanis 31 2007 carries 34 gallons versus 24 gallons on the Beneteau First 29 Deep draft 1983 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
