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.

Diesel engine winterisation

An inactive boat engine needs to be protected from corrosion during the winter, caused by the rising humidity levels through the cold months and the salty coastal air. This applies whether the boat is left afloat or hauled out over the winter. Read here about the two important stages of winterisaton for a diesel boat engine.

Boat maintenance – what does it involve?

The maintenance of a boat involves things like cleaning, varnishing, painting, polishing, antifouling, servicing the engine, servicing the seacocks, and maintaining the gas and plumbing systems. It all amounts to a fairly considerable amount of work that can’t be ignored if you are to keep your boat in a safe and good condition.

Wooden Hulls – Part 2

It is important to ensure the essential hull maintenance of a wooden boat is done, even if you are paying others to look after your boat for you. The priority is to prevent rot from taking hold. The protective layers of paint and varnish over wood are far more critical than on GRP boats, where the topsides are painted more for cosmetic reasons.

Tidal heights and the rule of twelfths

For those skippers who need to make a quick calculation or don’t have access to specific tidal curves for their location, it is possible to make an approximation using a system called the Rule of Twelfths. This is a simple method used to estimate the height of tide at any given time during the tidal cycle. It is based on the idea that the rise and fall of the tide is not constant, but follows a predictable pattern than can be divided into twelve parts.

Sailing at the touch of a button

Easier and more controlled sail handling can also be achieved by powering up a furling mast. I came across some interesting solutions at the Southampton Boat Show this week on the Selden Mast stand, where they were running demos of their E40i electric winch and SMF furling system.

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.

Nautical paper charts – a reminder of the basics

The nautical chart is an indispensable tool for navigation. A chart is a graphic representation of an area of the sea which might also include coastlines, estuaries and islands. All cruising leisure boats should carry up-to-date paper charts.

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.

Narrowboating on the Kennet and Avon Canal

A recently cancelled sailing event I was due to take part in left us with a free weekend in the diary. Given that my wife and I were celebrating a bumper wedding anniversary and the weather forecast was for fine weather, we decided to hunt around for a last minute canal holiday.

Propeller care and maintenance

Propellers are complicated and repairs should be done by specialists but owners can carry out checks and some routine maintenance themselves when the boat is in the boatyard. A propeller is critical to a boat’s performance, fuel consumption and ride, so it makes sense to keep a propeller in good working order.

Boat Security: Protecting your vessel from theft & vandalism

Boats are susceptible to theft and vandalism. Protecting your vessel from these risks requires a proactive approach to boat security. In this comprehensive guide, we’ll explore the various threats to boat security and provide practical strategies and technologies to safeguard your investment and enjoy peace of mind on the water.

How diesel engines work

The basic principle of a diesel engine is less complex than that of a petrol engine. No spark plug or ignition system is needed, making the basic diesel engine a comparatively straightforward system that results in fewer faults and has lower maintenance costs than a petrol engine.

Seacock maintenance

If seacocks are always left open and neglected they can eventually seize which will prove a serious threat to boat safety should a connecting hose fail and the seacock refuses to close. There are three main types of seacock – ball valves, cone valves and gate valves.

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.

Keel maintenance and repair – Part 1

Keels are designed to act as underwater foils that generate lift as the boat moves through the water, counteracting the leeward force of the wind and enabling the boat to sail closer to the wind. Keel maintenance and repair is essential for the performance of your boat.
