International DN Ice Yacht Racing Association

Historic First Website of the IDNIYRA
Created by Paul Goodwin

Even though much of the information on this website is out of date, the first website of the DN class contains useful articles assembled by Paul Goodwin that have remained important to the class.
For the most up to date information on membership, specifications, bylaws, regatta dates, etc. please go to the current website.

Loretta Rehe was asked to describe how she scores a regatta using the IDNIYRA scoring system, in particular what is affectionately known as the "Bart" rule.

Paul Goodwin has expanded on her explanation to provide a general description of scoring a major DN regatta from the scorer's "on the ice" perspective.

DN Class Plans

The Official Plans are now available for download! You can get the scale plans and view them on you computer, or print them out.

The printed plans are still for sale, but this provides a low-cost option to encourage more building.


IDNIYRA Bulletin Board

For the most up-to-date information, particularly concerning local ice conditions, and regatta dates/locations, please refer to the North American IDNIYRA Bulletin Board

While I try to maintain this website and keep the information fresh, users are able to post information on the bulletin board themselves, providing immediate updates.
