Sail Area Calculations
A spreadsheet has been put together that will take the hard work out of the calculations. There are two versions, one for Microsoft Office and the other for MAC Open Office. There is also a PDF file giving an example of how to use the spread sheet. This spread sheet is offered for free use by the UK RG65 Class Association and the results of the calculations will be accepted at any meeting with Open or National status, providing the drawing as described in the class rules, as per the example is included.

Measurement and Certification
At the moment there is no formal measurement requirement for the RG65 Class. Boats and rigs should be be self measured using the forms in the the class rules document.
