Input: Question: What is the length of the body of water that the Dutch ships avoided at the narrowest point? Passage:To avoid conflict with the English (with whom, due to the Third Anglo-Dutch War, the Dutch were at war), rather than passing through the English Channel, the ship was directed northwards where the plan would be to sail around the north of the British Isles (known as "going north about", which was commonly practised by Dutch East India ships at that time), before heading southwards again. Due to the extreme weather conditions in its journey northwards, the ship lost its masts and rudder, and southerly winds prevented the ship from being able to pass through either the Pentland Firth or the Fair Isle Channel, so the ship was (probably with considerable difficulty) taken into Ronas Voe in the north-west of Northmavine, Mainland, Shetland to shelter until the weather improved, and to allow the ship to be repaired. The voe (Shetland dialect for an inlet or fjord forms a crescent shape around Ronas Hill, which would have allowed the ship to lie sheltered regardless of the direction of the wind. A combination of prevailing southerly winds, and, presumably, a scarcity of suitable wood available in Shetland at that time to replace its masts prevented the ship from continuing its journey, and as such it remained in Ronas Voe until March 1674.
