Hints and Tips

Boating tips for your information

Docking

All of us boaties like to look professional when we dock our boats; it’s a boatie thing. Well, here’s a tip . The force from a propeller that drives a ship forward is known as ‘axial thrust’.  Transverse thrust is a sideways force that is also generated by the action of the propeller and is commonly known as ‘paddle wheel effect’.

Most propellers are ‘right-handed’ (that is, they rotate clockwise in forwards when viewed from astern).  Such propellers tend to paddle the stern to starboard when going ahead and to port when going astern.  The bow will appear to tending in the opposite direction.

Transverse thrust can be particularly useful in close quarter manoeuvring of ‘single screw ‘ ships but its direction and effect must be correctly anticipated.  For example; in single screw ships it is always easier to come along side a jetty on the port side.  When you approach the jetty at an angle in a forward motion and when the bow is reasonably close to the jetty, engage reverse gear and the transverse thrust will neatly bring the stern into the jetty.  However, when you approach on the starboard side the opposite will happen.  Of course there are always other considerations when docking your boat such as wind and tide etc, so you may not always be able to use this little trick.

Marine Radios – Silence Periods

To increase the safety of life at sea, two three-minute periods of radio silence must be observed in each hour.

They start on the hour and continue to three minutes past the hour, and on the half hour until 33 minutes past the hour.

With the exception of distress calls and messages, all transmissions from all stations must cease during these periods.
