Mooring lines are used when arriving or leaving a berth. One of the most important competent crew skills is to know how to handle and tie mooring lines securely and safely.

Mooring lines may be tied to a variety of purpose made objects ashore, including cleats, rings and posts. It is best to tie the end of a line to the shore and feed back the rest of it to the boat where any excess can be stowed neatly. The knots used will depend on the type of object the line is tied to. They include:

  • Cleat hitch – used for tying to a cleat.
  • Round turn and two half hitches – used for a ring or a post.
  • Bowline – a secure loop that can be used for a cleat or ring. 

Fairleads

Mooring lines are susceptible to chafe where they rub against cleats and various parts of the boat, a pontoon or a harbour wall. In order to protect against chafe, ropes are fed through devices called fairleads fixed to the boat. Some lines may be fed through thick plastic tubing to protect them. 

Berthed alongside

A number of lines are used to secure a boat alongside a pontoon or jetty.  The side of the boat is protected by fenders tied to the rail.

The bow line runs forward from the bows to the pontoon, the stern line runs back from the stern. Other lines, called “springs” run backwards from the bow and forwards from the stern. These lines stop the boat from moving backwards and forwards along the pontoon, holding it steady alongside.

Berthed stern-to

If a boat is berthed stern-to, where the stern is backed up to the pontoon or quay, it will have two stern lines holding it in place. The bow will be held by an anchor or mooring buoy ahead of the boat.

Allowing for tide

Allowance needs to be made for the rise and fall of the tide when a boat is berthed alongside a quay in tidal waters.  This means either the mooring lines will need to be adjusted by the crew as the tide rises or falls, or sufficient slack needs to be left in the lines to allow for the rise and fall of the tide.

No adjustments to the lines need to be made when tied up alongside a pontoon. This is because pontoons are floating and are designed to rise and fall with the tide. 

Tips:

  • Spring lines stop a boat from moving forwards and backwards when alongside.
  • Learn the best knots to use to secure lines to cleats, rings or posts.
  • Don’t leave excess line on the pontoon, stow it neatly on the boat.

Going aground – what to do if it happens to you

When a yacht runs aground, it can be a stressful situation, especially on a falling tide in an exposed position with a swell running. There are several steps you can take to address the situation in order to ensure the safety of your vessel and its occupants. Here are some tips should this happen to you.

Repairing chips and dings in gelcoat

The gelcoat topsides of a GRP boat can be pampered and restored to their former glory relatively easily when it is ashore. Gelcoat is only a very thin outer layer of the hull, often less than 1mm thick, so you should avoid cleaning it with highly abrasive cleaners, or an-ything that could potentially damage its surface.

Wooden Hulls – Part 1

Traditional wooden boats have a plank on frame construction, a centuries old boat building method that is still in use today. Variations of the traditional method include carvel, clinker and strip planking, which all relate to the way the planking is attached to the frame.

Understanding boat engines

Irrespective of what kind of engine a boat is equipped with and who does the work, the regular care and maintenance of a marine engine is essential. The most common cause of marine engine failure is widely known to be lack of maintenance.
