Spiral (dinghy)

Spiral is a rarely used, informal name for a specific type of small sailing dinghy, characterized by its hull design. While no standardized design exists under this name, the term generally refers to a dinghy with a pronounced curved or spiral-like shape to its hull sides, often intended to improve stability and/or performance in certain conditions. These characteristics are not unique to any particular manufacturer or design, and the name "Spiral" is more likely a nickname or locally-used term rather than an official class designation. Further research is needed to identify specific instances of dinghies known by this name and to determine if any common design features beyond the aforementioned hull curvature can be identified. Information regarding construction materials, sail plans, or typical dimensions remains scarce.
