Indispensable Strait

Map of Indispensable Strait and Guadalcanal island.

Indispensable Strait is a waterway in the Solomon Islands, running about 200 km northwest-southeast from Santa Isabel to Makira (San Cristóbal), between the Florida Islands and Guadalcanal to the southwest, and Malaita to the northeast.

Indispensable Strait is part of the navigation route for merchant shipping from Torres Strait to the Panama Canal. It is one of three major routes for merchant shipping through the Solomon Islands; the routes are the Bougainville Strait and Indispensable Strait, which link the Pacific Ocean, Solomon Sea and Coral Sea; and the Manning Strait that links the Pacific to New Georgia Sound, which is also known as ‘The Slot’, through which Japanese naval ships resupplied the garrison on Guadalcanal during the Pacific War.^[1]

Captain William Wilkinson, in the merchantman Indispensable, discovered the strait in 1794.^{[Note 1]}
