One prolonged blast
One prolonged blast
A power-driven vessel under way sounds one prolonged blast not less than every two minutes. However if it is less than 12meters in length it is not required to give any signal.
A power driven vessel making way shall sound at intervals of not more than 2 min one prolonged blast. A power driven vessel under way, but stopped & no making way, shall sound at intervals of not more than 2 min two prolonged blas in sucession, at intervals of about 2 sec between them.7 blasts
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
the power driven vessel needs to give-way for sailing ships.
There are several sound signals for a vessel underway in restricted visbility.A power drivel vessel underway, making way- 1 PROLONGED Blast (4-6 seconds duration) Not to exceed every two minutes.A power driven vessel underway NOT making way-2 PROLONGED every 2 minutes, not exceed two minutes.A vessel not under command, a vessel restricted in maneuverability, a vessel towing, a vessel engaged in fishing, a sailing vessel & a vessel constrained by her draft (International only) 1 PROLONGED blast followed by two short blast (duration about 1 second per short blast) every two minutes, not to exceed two minutes.A MANNED vessel being towed shall sound 1 PROLONGED followed by 3 SHORT blasts every two minute, not to exceed two minutes.See the link provided for the International and Inland Navigational Rules of the Road. Rule 35.for power driven vessels over 12meters it's one long blast every 2 minutes
A power driven vessel is often understood to be a mechanically driven boat. Human power as in rowing or wind driven power is not usually considered power driven.

Rules of the RoadInternational/InlandLights & shapesRule 23-Power-driven vessels underway(a) A power-driven vessel underway shall exhibit:(i) a Masthead light forward;(ii) a second masthead light abaft of and higher than the forward one; except that a vessel of less than 50 meters in length shall not be obliged to exhibit such a light but may do so;(iii) sidelights; and(iv) a stern light*note on side lights. Red is port side (left) and green is starboard side (right)
**Not sure why this was flagged, I hand typed this.Rules of the RoadRule 9-Steering & Sailing RulesInternational/Inland(b) A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel that can safely navigate only within a narrow channel or fairway.***This applies to sailing vessels that are tacking in a channel or fairway.Rule 18Steering and Sailing Rules.Responsibilities Between Vessels.Except where Rules 9,10 and 13 otherwise require:(a) A power driven vessel underway shall keep out of the way of:(iv) a sailing vessel.(b) A sailing vessel underway shall keep out of the way :(i) a vessel not under command(ii) a vessel restricted in her ability to maneuver .
A vessel that is underway but not making way would exhibit sidelights if it is a power-driven vessel or a sailing vessel with a motor. Sidelights consist of a green light on the starboard side and a red light on the port side, indicating the vessel's orientation. Even when not making way, the sidelights serve to signal the vessel's presence and direction to other vessels in the vicinity. Additionally, a vessel at anchor would display an all-round white light instead of sidelights.
