Changes to J/80 Class Rules

The J/80 Class is a "World Sailing Recognized" class, meaning that all changes to Class Rules and the Constitution must be approved not only by the J/80 Class but by World Sailing as well. This is a positive, in that the World Sailing subcommittees that deal with class rule changes have a great deal of experience across a number of classes. The side effect is that the process can be lengthy.

Under the ICA (International J/80 Class Association) Constitution, the ICA Executive Committee is responsible for managing the class affairs, which includes modification of the Class Rules and Constitution. To date, rules change proposals have generally come from an NCA (National J/80 Class Association), a measurer or a licensed builder. The proposals are reviewed/screened by the ICA Technical Committee, then a resolution is returned to the Executive Committee for vote after a review period.

How does one go about submitting a rules change proposal?

There are three conduits to the ICA Executive Committee. 1st is the National Class Association (NCA) representative to the ICA Executive Committee; 2nd is the NCA representative to the ICA Technical Committee, and 3rd is the Copyright Holder (J-Boats).

In general, there are three types of rules changes:

1. Typos and minor grammatical corrections needed to more clearly define the existing rules.
2. Measurement related wording changes, usually a result of measurers' experience in the field.
3. Equipment or racing related changes (like crew weight, sails, etc.) that impact the way the boat is sailed.

Proposals involving type 1 & 2 changes are always encouraged and can be submitted to the J/80 NCA Executive Committee by any Member. If not self-evident, the proposal should include reasons for the change. Proposals of type 3 variety should first have the backing of an exisiting J/80 fleet or at least 20 J/80 Members before being considered. This is a minimum "acid test" so that the class is not inundated with individual requests for rules changes that haven't demonstrated wider grass-roots support.


The normal World Sailing procedure calls for all Class Approved rules proposals to be received by their office no later than August 31 of the year preceding the desired implementation date. The standard World Sailing implementation date for new Class Rules is the March 1st following approval at their November meeting. While International Classes are able to obtain approval for rules changes on a year-round basis, the following is the J/80 Class adopted guideline for J/80 rules proposals:

April 15 - Deadline for submission of rules proposals to ICA ExCom.
Jun 15 - Deadline for ICA Technical Committee to formulate resolutions and return to ExCom.
Aug 15 - ICA ExCom Meeting (teleconference) to vote on resolutions.
Aug 31 - Submission of approved resolutions to World Sailing.
Nov 30 - World Sailing approves/rejects submissions.
Mar 1 - Implementation date of new rules.

This timetable allows 90 days for each NCA to review with their class Members prior to an ICA vote.
