Hvad er definitionen på off shore egentlig?

Vi kan hurtigt blive enige om at Volvo Ocean Race og Vendee Globe er offshore sejladser, men hvornår er man offshore og hvornår er man ikke. Det er ikke så ligetil.
En hurtigt internetsøgning gav flere bud på offshore, men absolut ingen præcis definition:

  • Uden for rækkevidde af kapsejladskommiteen
  • Indeholde natsejlads
  • Kan ikke se land.
  • Kan ikke nå i sikker havn inden for perspektivet af en sandsynlig vejrudsigt.
  • Mindst 24 timer fra land i forhold til bådens hastighed.
  • 12-20 nm fra land
  • Udenfor rækkevide af rescue services
  • Uden mulighed for at søge beskyttelse fra vejrliget.
  • Vanddybden
  • Åbent hav hvor der definitivt ikke er land som påvirker vind og bølger

Man kunne måske søge information hos ISAF http://www.sailing.org/specialreg som international sejlsportsorganisation ISAFs Special Regulations inddeler offshore i 6 kategorier. Se nederst.
Det synes jeg egenligt ikke at blive klogere af. Før jeg læste dette vil jeg definitivt have ment, at man ikke er offshore i cat 2 og opefter sejler. Cat 5 og 6 er jo paradoksalt nok benævnt som inshore. Jeg ved ikke om jeg ikke hellere vil vælge en af lommereglerne ovenfor.
2.01.1 Category 0
Trans-oceanic races, including races which pass through areas in which air or sea temperatures are likely to be less than 5 degrees Celsius other than temporarily, where yachts must be completely self- sufficient for very extended periods of time, capable of withstanding heavy storms and prepared to meet serious emergencies without the expectation of outside assistance.
2.01.2 Category 1
Races of long distance and well offshore, where yachts must be completely self-sufficient for extended periods of time, capable of withstanding heavy storms and prepared to meet serious emergencies without the expectation of outside assistance.
2.01.3 Category 2
Races of extended duration along or not far removed from shorelines or in large unprotected bays or lakes, where a high degree of self-sufficiency is required of the yachts.
2.01.4 Category 3
Races across open water, most of which is relatively protected or close to shorelines.
2.01.5 Category 4
Short races, close to shore in relatively warm or protected waters normally held in daylight.

Please refer to Appendix L where Special Regulations for Category 6 are given in full. The symbol ” ** ” does not include Category 6

participating boats may not be self-sufficient the races are short in duration and close to a single manned shore base, in relatively warm and protected waters, in daylight and good visibility participating boats can be observed by race organisers at all times safety/rescue boats are available all along the course sufficient to enable any competitor to be returned to the shore base in a timely manner safety/rescue boats are of a suitable designed and properly equipped and are manned by adequately trained and competent personnel including, for each race, at least one skilled in first aid
