About the FIRST 456 (BENETEAU)
The FIRST 456 was available with many different rig and keel options/combinations. Shoal draft keel and keel/cb. At least 3 different masthead rigs. KEEL/CB BD: 8.00'/2.44m; BU: 5.08'/1.55m Tot. SA (100%): 970.97 ft2 / 90.20 m2 TALL RIG 2: I: 60.80'/18.53m J: 17.60'/5.36m P: 54.30'/16.55m E: 16.30'/4.97m Tot. SA (100%): 977.59 ft2/90.82 m2
Designed by German Frers and built by Beneteau in France, the First 456 is a 45.5 ft masthead sloop with a production run starting in 1982. With a displacement of 26500.0 lb and a beam of 14.08 ft, this vessel represents a substantial cruising platform from the early 1980s, though the exact total hulls built is unknown.
- Best for:
- This boat suits coastal and offshore cruisers seeking a spacious, heavy-displacement vessel with a comfortable motion, as indicated by its 29.38 comfort ratio. It is well-suited for couples or families who prioritize interior volume and stability over high-performance racing metrics.
- Bluewater capability:
- With a displacement of 26500.0 lb, a capsize ratio of 1.89, and a fin keel with 8.0 ft max draft, the First 456 is structurally robust for offshore passages, though potential keel sump cracking requires careful verification.
- Comparables:
- Comparable boats include the Beneteau First 405 and First 365, which share the same German Frers design lineage and similar heavy-displacement cruising characteristics. Other contemporaries like the Hallberg-Rassy 42 or Tartan 42 offer similar bluewater credentials but with different construction methods.
