The Beneteau First 30E 1981 vs Beneteau Oceanis 300 Shoal draft 1991 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 30E 1981 at 31,1 ft versus Beneteau Oceanis 300 Shoal draft 1991 at 31,1 ft. Weight tells a clearer story for trailering families: the Beneteau First 30E 1981 tips the scales at 8 929 lbs - 1 874 lbs more than the Beneteau Oceanis 300 Shoal draft 1991 at 7 055 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 - 15 hp for the Beneteau First 30E 1981 and 24 hp for the Beneteau Oceanis 300 Shoal draft 1991. 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 300 Shoal draft 1991 carries 17 gallons versus 8 gallons in the Beneteau First 30E 1981. 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.
Both boats sit in a similar displacement bracket - 8 929 lbs for the Beneteau First 30E 1981 and 7 055 lbs for the Beneteau Oceanis 300 Shoal draft 1991. 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 - 5,1 ft and 4,5 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.
The Beneteau First 30E 1981 uses Sloop rigging. For auxiliary power the Beneteau Oceanis 300 Shoal draft 1991 carries a 24-hp engine against 15 hp on the Beneteau First 30E 1981. 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 300 Shoal draft 1991 and 6,7 knots for the Beneteau First 30E 1981. For extended cruising, water capacity matters: the Beneteau Oceanis 300 Shoal draft 1991 carries 45 gallons versus 26 gallons on the Beneteau First 30E 1981 - a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
Bottom line: The Beneteau First 30E 1981 and Beneteau Oceanis 300 Shoal draft 1991 are closely matched on paper. A sea trial on both in representative conditions is the only reliable way to find which one suits your sailing style, home port, and intended cruising ground.
