Side 2 - ... (c) Assumptions shall not be made on the basis of scanty information, especially scanty radar information. (d) In determining if risk of collision exists the following considerations shall be among those taken into account: (I) Such risk shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change...
Side 4 - When two steam vessels are crossing, so as to involve risk of collision, the vessel which has the other on her own starboard side shall keep out of the way of the other.
Side 111-108 - A vessel shall not cross a narrow channel or fairway if such crossing impedes the passage of a vessel which can safely navigate only within such channel or fairway.
Side 111-109 - A vessel nearing a bend or an area of a narrow channel or fairway where other vessels may be obscured by an intervening obstruction shall navigate with particular alertness and caution and shall sound the appropriate signal prescribed in Rule 34(e).
Side 4 - ... shall be deemed to be an overtaking vessel; and no subsequent alteration of the bearing between the two vessels shall make the overtaking vessel a crossing vessel within the meaning of these rules, or relieve her of the duty of keeping clear of the overtaken vessel until she is finally past and clear.
Side 3 - In a narrow channel or fairway when overtaking can take place only if the vessel to be overtaken has to take action to permit safe passing, the vessel intending to overtake shall indicate her intention by sounding the appropriate signal prescribed in Rule 34(c)(i).
Side 4 - A vessel which is close-hauled on the port tack shall keep out of the way of a vessel which is close-hauled on the starboard tack. (c) "When both are running free, with the wind on different sides, the vessel which has the wind on the port side shall keep out of the way of the other.
Side 2 - Alteration of course alone may be the most effective action to avoid close quarters provided that: (a) There is sufficient sea room.
Side 4 - When two steam- vessels are meeting end on, or nearly end on, so as to involve risk of collision, each shall alter her course to starboard, so that each may pass on the port side of the other.
Side 95 - A steam vessel hearing, apparently forward of her beam, the fog signal of a vessel, the position of which is not ascertained shall, so far as the circumstances of the case admit, stop her engines, and then navigate with caution until danger of collision is over.
