International Division II Class Association ( ID2CA)

Logo_D2_300_fWe are proud to announce the creation of the International Division II Class Association (ID2CA) which will also be an associate member of the International Windsurfing Association (IWA). Our goals are to regroup windsurfers sailing Division II sailboards as well as to promote and develop again the Div II Class throughout the world.

A Division II sailboard is defined as a round bottom sailboard built to International Displacement Division Measurement Rules initially set by the International Board Sailing Association (IBSA) and approved by the International Yacht Racing Union (IYRU) from 1979 to 1992. An objective of ID2CA is the conception and production of new Division II boards and sails using new technologies, according to existing Class Rules (1979-1992).

Under Class Rules (1979-1992) two racing divisions are defined – Category A and Category B.

ID2CA have developed Class Championship Rules to define how their championship racing shall be organised, and these rules also include an Addendum to Class Measurement Rules (1979-1992) that introduce the concept of a Category C division within the Class.

Category A

– Boards built between 1979 and 1992, which are compliant with Class Rules (1979 – 1992).
– Type A sails: triangular ‘one-design’, short-battened sails with maximum sail area of 6.5 sq.m.

Category B

– Boards built between 1979 and 1992, which are compliant with Class Rules (1979 – 1992).
– Type B sails: fully battened with a maximum sail area of 7.5 sq.m.

Category C

– Boards that are not 100% compliant with Class Rules (1979-1992) but must comply with Class Rule dimensions and meet the Category C Addendum requirements.
– Open in design and use of materials; with maximum sail: size 9.5 sq.m for heavyweight men, 8.5 sq.m for women and lightweight men.
