The essence of the evaluation procedure lies in the analysis of a number of interrelated and fully documented trial measurements which shall meet the following requirements:
1. At least three double runs at different engine loads, with and against the wind shall be conducted.
2. Reliable measurements of ground speed, shaft speed, shaft torque and apparent wind are to be carried out.
3. Contract conditions regarding draft, trim, hull and propeller conditions shall be met.
4. Speed trials shall be carried out in favorable environmental conditions.
