Spiral (dinghy)

Single‑handed sailing dinghy (one‑design class)Early 1970s (first built 1973); production details limited / regionally variable

The Spiral is a small single‑handed fibreglass dinghy designed by Alan Warwick in the early 1970s. It is a compact, relatively light boat intended for one person and often raced or sailed recreationally where a Laser‑sized single‑hander is needed but a slightly smaller hull suits lighter sailors.
