Statement on Hull Measurement

As a result of issues during the measurement checks of a number of boats from several designs at the OK Dinghy World Championships in Warnemünde Germany 2008 the OKDIA Technical Committee agreed to evaluate these issues.
The following statement aims to give clarity on how boats are measured and on how the current rules should be interpreted. The Technical Committee will continue to evaluate ways to better control future measurement within the class.

Trim guide

Nick Craig wrote a brief trimming guide, older guides are not much help anymore as the class went for carbon masts in 2003.
The guide is in pdf (Acrobat Reader) format, for easy print out.

Technical Manual

This Technical Manual is based on a print version from the british association.
It is very old, some information is based on wooden masts, while carbon masts are the standard, so take care with the information given, some might be out of date.
As some new OK sailors still find some information in this manual useful, we published it.
