The National 12 is a twelve-foot-long dinghy sailed by two people. The class dates back to 1936 when the RYA wanted an alternative to the expensive international 14 class.

This class is a “development” class, so each boat can be built within a set of rules. This means there is quite a range of different shapes and set up’s found across the fleet.

This fitting list is based on a Dead Cat Bounce design and is just a guide to help choose the correct fittings.
