One boat is clear astern of another when her hull and equipment in normal position are behind a line abeam from the aftermost point of the other boat’s hull and equipment in normal position. The other boat is clear ahead. They overlap when neither is clear astern. However, they also overlap when a boat between them overlaps both. These terms always apply to boats on the same tack. They apply to boats on opposite tacks only when rule 18 applies between them or when both boats are sailing more than ninety degrees from the true wind., Üks paat on teisest paadist vabalt taga, kui ta normaalasendis kere ja varustus on tagapool teise paadi normaalasendis kere ja varustuse ahtripoolseima punkti traaversit. Teine paat on vabalt ees. Nad on seotud kui kumbki neist ei ole vabalt taga. Kuid nad on seotud ka siis kui nende vahel olev paat seob neid mõlemaid. Need terminid kehtivad alati paatidele, mis on samal halsil. Need kehtivad paatidele, mis on erinevatel halssidel ainult siis kui reegel 18 kehtib nende vahel või kui mõlemad paadid purjetavad rohkem kui üheksakümmend kraadi tõelisest tuulest.
