Gybing is the sailing manoeuvre used to change a boat’s direction through a following wind. As with the tacking manoeuvre, gybing a sailing boat calls for the crew to work together as a team and is one of the first sailing skills to learn.

When a boat is sailing downwind, with the wind blowing from behind the yacht, it may need to alter course so that the stern goes through the wind. This requires a sailing manoeuvre called a gybe, where the sails move from one side of the boat to the other.

The aim is to turn the stern smoothly through the wind onto the new course in as controlled a manner as possible. This means the boom of the mainsail has to be controlled carefully through the turn and the boat must not be allowed to swing round and turn sideways to the wind, causing it to heel over.

As when tacking, the gybe manoeuvre calls for a well co-ordinated crew and clear instructions from the skipper and helm.

Gybe manoeuvre

The gybe manoeuvre can involve two or three crew members and goes as follows:

  • The skipper or helm decides it is time to gybe and alerts the crew.
  • Helm calls “Ready to gybe!”
  • The mainsheet is pulled in to bring the boom to the centre line.
  • If there is a mainsheet traveller, this is cleated to hold the boom in place.
  • One or two crew members are put in control of each jib sheet winch, depending on the size of the boat and number of crew available.
  • A crew member then puts two turns of the slack or “lazy” jib sheet around the winch (A) on its side of the cockpit and pulls in the slack. Another crew member un-cleats the “working” jib sheet, keeping it tight on the winch (B).
  • The helm turns the boat slowly to allow the wind direction to pass from one side of the stern to the other. Once the turn is complete the helm calls “Gybe-oh!”
  • As the boat turns, the headsail blows from one side of the bow to the other. The crew on the working sheet eases and releases the sheet from winch (B).
  • The crew on winch (A) then pulls in the new working sheet. The winch handle is inserted into the top of the winch, the crew winches in the sheet and the sail is trimmed for the new course.
  • The helm steers the boat onto its new course and the mainsail is let out on the new side.
  • Both sails are then trimmed for the new course.

Tips:

  • It is very important to sheet in the mainsail to the centreline before gybing, to prevent the boom swinging across in a dangerous, uncontrolled manner.
  • All crew should keep their heads well down away from the boom during a gybe in case it swings across unexpectedly.

Boat batteries

Under-sized battery banks are one of the key factors behind power failure at sea, as well as the premature failure of batteries, so make sure that your boat battery measures up to the use you want to put it to.

Sailing to windward – how to take advantage of wind shifts

For most sailors, sailing upwind is the most exhilarating point of sail as you tack your way to your destination. Sailing to windward is a bit like zig-zagging your way up a mountain road through a series of hairpin bends – great fun but also calling for concentration and hard work.

Stern gear maintenance

The stern gear of a boat needs to be checked carefully when the boat is ashore as this is something that can only be done when it is out of the water. The same applies for any maintenance and repairs that may need doing, so it is best to check it all over as soon after an end of season lift out as possible.

Fractures, sprains and dislocations at sea

Moving about a boat at sea often results in a few knocks and bruises, but if a crew member has a fall or major bump and is in serious pain, they should be examined and treated accordingly.

Boat decks and superstructure

The deck of a boat is constantly exposed to the elements and should be inspected on an annual basis. Particular attention needs to be given to the overall condition of deck fittings such as the stanchions, cleats and chainplates.

Fixing position at sea using traditional methods

This post looks at some traditional methods used for fixing a vessel’s position at sea, within sight of land. Electronic fixes using chart plotters are very straightforward to record, but if for some reason a vessel’s electronics are faulty it is essential that a skipper knows how to use traditional methods.

Sterndrive maintenance

Sterndrives are a popular form of propulsion in the powerboat market, but require a fair amount of care and maintenance. The main factors to be aware of are salt water corrosion, lubrication and regular inspection of the bellows, the condition of which is vital to prevent water from entering into the hull.

Boat maintenance below decks

While most interior maintenance work can be done when a boat is afloat, some jobs such as servicing the seacocks have to be done ashore. It makes sense to do any major interior repairs and improvements with the boat hauled out in the boatyard.

Boat engine cooling systems

Some boat engine breakdowns are unavoidable but those caused by lack of maintenance or regular checks can be avoided. Failure to maintain an engine’s cooling system is a well known example of this, so it is well worth spending time checking over the cooling system both when the boat is ashore and afloat.

Sailing Safely at Night – Best Practice

Engine failure at sea – common causes and how to avoid them

Many engine failures are caused by lack of maintenance, resulting in fuel filter blockages, water pump failures, overheating and other breakdowns. Indeed, one of the most common reasons for marine rescue service call outs is for one of the most basic reasons possible – boats that have run out of fuel.
