About the FIRST 21.7 (BENETEAU)
The extremely successful FIRST 21 series includes FIRST 210, FIRST 210 Spirit, FIRST 211, FIRST 21.7, FIRST 21.7S, all sharing the same basic hull design.
Designed by Groupe Finot and built by Beneteau starting in 2004, the First 21.7 is a compact, performance-oriented daysailer with a fractional sloop rig. With a displacement of 2745.0 lb and a comfort ratio of 12.94, it prioritizes speed and agility over heavy cruising comfort.
- Best for:
- This boat is ideal for coastal day sailing, racing, and trailerable cruising, appealing to single-handers or couples seeking a low-maintenance, high-performance package. Its light displacement and manageable size make it suitable for those with limited storage or launch facilities.
- Bluewater capability:
- With a capsize ratio of 2.33 and a low displacement of 2745.0 lb, this boat is not designed for offshore bluewater cruising and is best restricted to coastal and protected waters.
- Comparables:
- Comparable boats include the Beneteau First 21.5 and the J/24, as they share similar fractional sloop rigs, light displacement characteristics, and a focus on performance sailing. The Hunter 22 is also a relevant comparison for trailerable daysailing, though with different hull form priorities.
