Right of visit
In international maritime law, right of visit (also right of visitation, right of search) allows a belligerent warship during wartime to stop and board a neutral merchant ship in order to verify that the ship nationality matches the declared one and its operation does not break a naval blockade, does not involve contraband, and does not provide non-neutral services to the enemy. The use of word "visit" probably refers to a misunderstanding of the French word visite, which in this context means search.
