BIMCO Evidence of Performance Clause 2006
The actual route taken by the Vessel shall be used as the basis of any calculation of the Vessel's performance under this Charter Party.
Owners and Charterers agree that evidence of the weather, sea state and other factors affecting the vessel’s performance shall be taken from the vessel’s log book unless such data is substantially contradicted by the ‘final report’ of an independent weather routeing service supported by data obtained from a weather authority that is a member of the World Meteorological Organization.
