The Spiral is a type or class of sailing dinghy. It is similar to a Laser (dinghy), but is smaller and easier to manoeuvre on land and in water, and suited to a skipper of smaller body weight and more fun to sail in heavier conditions than is a Laser due to its greatly improved wider interior for the sailor.
