Current through Register Vol. 48, No. 1, January 10, 2025
Section 2 CCR 405-2-221 - MANEUVERING AND WARNING SIGNALS1. Terms used: a. "Short blast" means a blast of about one second's duration sounded when motorboats are at a close quarters distance so as to involve the risk of collision.b. "Prolonged blast" means a blast of four to six seconds' duration sounded when motorboats are at a close quarters distance so as to involve the risk of collision.c. "Danger signal" means five or more short blasts.2. When motorboats are in sight of one another and meeting or crossing at a close quarters distance so as to involve the risk of collision, each motorboat underway, when maneuvering as authorized or required by the rules of the road shall indicate that maneuver by the following signals from the sound-producing device:a. One short blast to mean "I intend to leave you on my port side."b. Two short blasts to mean "I intend to leave you on my starboard side."c. Three short blasts to mean "I am operating astern propulsion."d. Upon hearing the one or two blast signal, the other shall, if in agreement, sound the same signal and take the steps necessary to effect a safe passing. If, however, from any cause, the motorboat doubts the safety of the proposed maneuver, then the danger signal shall be sounded and each vessel shall take appropriate precautionary action until a safe passing agreement is made.3. When motorboats are in sight of one another and one motorboat is intending to overtake another at a close quarters distance so as to involve the risk of collision, the overtaking vessel shall indicate intentions by the following signals from the sound-producing device: a. One short blast to mean "I intend to overtake you on your starboard side."b. Two short blasts to mean "I intend to overtake you on your port side."c. Upon hearing the one or two blast signal of the other, the motorboat this is being overtaken shall, if in agreement, sound the same signal. If in doubt, the vessel being overtaken shall sound the danger signal.4. When vessels, other than hand-propelled vessels when on whitewater, are in sight of one another and are approaching each other and from any cause either vessel fails to understand the intentions or actions of the other, or is in doubt whether sufficient action is being taken by the other to avoid collision, the vessel in doubt shall immediately indicate such doubt by giving at least five short and rapid blasts from the sound-producing device. The danger signal may be supplemented by a light signal of at least five short and rapid flashes.5. When a motorboat is leaving a dock or berth and vessel traffic is heavy, one prolonged blast may be sounded.6. If necessary to attract the attention of another vessel, any vessel may light or sound signals that cannot be mistaken for any signal authorized elsewhere in these regulations, or may direct the beam of a light in the direction of danger.7. When a vessel is in distress, the following signals used or exhibited either together or separately, indicate distress and need of assistance:a. A continuous sounding with any signaling device;b. A signal made by any signaling method consisting of S.O.S. in the Morse Code;c. Slowly and repeatedly raising and lowering arms outstretched to each side;d. An orange distress flag with either a black square and circle or other appropriate symbol;e. A high intensity white flashing light flashing at regular intervals from 50 to 70 times per minute.f. The use or exhibition of any of the foregoing signals except for the purpose of indicating distress and need of assistance is prohibited.37 CR 19, October 10, 2014, effective 11/1/201438 CR 07, April 10, 2015, effective 5/1/201539 CR 03, February 10, 2016, effective 3/1/201639 CR 07, April 10, 2016, effective 5/1/2016
