The present APPLIES TO rules for international waters. In waters under the jurisdiction of any nation this rules can suffer form any alteration.

The marine navigation lights are those installed aboard any vessel in order to alert other ships in the area of ​​their presence, reporting capabilities maneuver forward direction and special features to make in terms of a correct identification facilitate maneuvers designed to avoid collisions.

The characteristics of navigation lights, colors, bows visibility, scope and relative installation position, are established by the International Regulations for Preventing Collisions at Sea (RIPA)

Listed below is a brief description of the set of lights must display the boats according to the particulars of each characteristic.

  • Caso 27d

  • Caso 27d2

  • Caso 27e2

  • Caso 27f

Vessels constrained by draft

Definition: A vessel constrained by her draft means a power-driven vessel which, because of her draft in relation to the available depth and width of navigable water, is severely restricted to deviate from the course she is following capacity. (Case 28)

In addition to the lights corresponding to its length as power-driven vessel shall exhibit three red lights in a vertical form of all-round.

  • case 28

Vessels practical
