Rules & Regulations
Sailing speed record attempts for all boat categories are overseen and verified by the World Sailing Speed Record Council (WSSRC).
The WSSRC was established by the International Sailing Federation (ISAF) in 1972 to formalise the sailing records and verify any future attempts at the records. Listed below is a summary of the rules relating to the records which we are attempting, full details of the rules can be found at the WSSRC website.
Outright Speed Record (500m & 1nm) Course
The record must be established over a course on water (not ice) with a minimum length of 500 meters/1 nautical mile.
The boat must use only human power apart from battery power for instrumentation. No means of power or stored energy may be used. The boat, with at least one person aboard at all times, must float at rest and be positively buoyant before, during and after any record attempt. Propulsion must only be via the natural action of the wind, and without any element of assistance from "wave riding".
In order to establish a new record the new elapsed time (corrected to 500 metres precisely) must improve on the existing record by 1/100th of a second if using WRRSC ratified GPS equipment with allowance made for the resolved component of any tidal stream and/or current on the course. A venue is not suitable for record breaking if the current is more than one knot.
Offshore Courses
Only fixed points of land, fixed navigational beacons or other charted objects fixed to the land or seabed can be used as reference points. Positions derived from radio or satellite navigation systems are unacceptable.
The start and finish lines shall be crossed within 4 nm of a WSSRC observer with the times logged and signed by the observer or his appointee. The moment of starting and finishing a passage must be recorded to the nearest second using Coordinated Universal Time (GMT). The accuracy must be checked within six hours of the start and finish of the attempt by reference to an official time signal by telephone or radio.
Records and performances will always be defined as an elapsed time in days, hours, minutes and seconds with average speed shown for information only.
Propulsion of the vessel must be solely by natural forces and the vessel must be capable of floating and supporting its crew when at rest. Prior to the attempt, the vessel must be at rest, afloat and must accelerate without assistance.
24 Hour Distance Record
Timed position reports from the vessel must be GPS positions which are then transmitted onwards to an approved base station or directly to an official observer appointed by WSSRC. The onward transmission shall be via Inmarsat, GPS Argos or another system capable of being polled by the base station. The essential feature is that the timed GPS position reports must be collected and forwarded without any action by the crew of the vessel.
The data shall include the time in Coordinated Universal Time (GMT) to the nearest minute and the latitude and longitude to the nearest tenth of a minute. The 24-hour period may begin at any time. For a distance to be ratified as a record, it must be at least one nautical mile greater than the previously ratified record.
