Power-driven vessel, underway and making way. |
 |
At not more than
two minute intervals.
Power-driven vessel, underway but not making way. (blast 2 long, I'm waiting too long) |
 |
At not more than
two minute intervals.
Any of the following: A sailing vessel. A vessel fishing. A vessel not under command. A vessel restricted in ability to manoeuvre. A vessel constrained by draught. A vessel towing. |
 |
At not more than
two minute intervals.
A vessel under tow, or the last vessel on a line of vessels under tow. (long and 3 short, tow line is taut) |
 |
At not more than
two minute intervals.
A pilot vessel on duty. |
 |
At not more than
one minute intervals.
A vessel less than 100 metres in length, at anchor. |
 |
At not more than
one minute intervals, a
bell at the bow and the gong at the stern. A vessel greater than 100 metres in length, at anchor. |
 |
At not more than
one minute intervals.
A vessel less than 100 metres in length aground. |
 |
Sounded after
the anchor signal for a
vessel of her size. An extra signal to give warning of the risk of collision to an approaching vessel, given by a vessel at anchor. |
A vessel of less than 12 metres in length is not obliged to make these signals, she only needs to make some efficient sound signal at not more than two minute intervals.
Anyone who does not make a sound signal in reduced visibility would be taking a considerable risk, and considering how easy it is to have a gas powered horn or a trumpet type horn aboard they would be very foolhardy.
