Boat balance - If a yacht is allowed to heel away from the wind, it will tend to turn into the wind or luff up. If the boat is allowed to heel towards the wind, it will tend to turn downwind or bear away. In either ease some rudder movement will be needed to keep it on course, which will slow the boat down. Turn the boat using the wheel to the desired course to steer. This may be a definite bearing or towards a landmark, or at a desired angle to the apparent wind direction.
Trim fore and aft - The distribution of crew weight fore and aft is just as important as balancing the boat. The best way to learn the techniques is to practice them, but the idea of shifting your weight towards the wind will help. In other words, that means moving forward in the boat when sailing to windward and moving aft when sailing downwind. The aim is to adjust the position of the crew forwards or backwards to achieve an 'even keel'. In a small boat and on an upwind course, the crew will normally sit forward, when 'running' it is more best for the crew to sit to the rear of the boat. The position of the crew matters less as the size (and weight) of the boat increases
Sail setting - A sail should be pulled in until it fills with wind, but no further than the point where the front edge of the sail (the luff) is exactly in line with the wind. As a guide, you will find that any sail, whether jib, mainsail or spinnaker, will set best by letting out until it starts to flap gently along the leading edge, then pulled in just enough to stop that flapping.
Centreboard - As well as driving a yacht forward, the action of the wind on the sails will push it sideways across the water - this is known as making leeway. To prevent this, the yacht needs more grip on the water, which is provided by a centreboard daggerboard or keel. The difference is simple. A centreboard will pivot around the bolt in its case; a daggerboard is moved vertically up and down In some older yachts you might find a metal board, referred to as a centreplate, all three do the same job. If a moveable centreboard is fitted, then it should be lowered when sailing "close to the wind" but can be raised up on downwind courses to reduce drag. The centreboard prevents lateral motion and allows the boat to sail upwind. A boat with no centreboard will instead have a permanent keel, some other form of underwater foil, or even the hull itself which serves the same purpose.
Course made good - This is the shortest distance between two points. The course made good will be a straight line from start to finish. In all other conditions you need to decide on the best way of getting from A to B.
Together, these points are known as 'The Five Essentials'.

It is a fact, daily stressed by doctors, dieticians and medical authorities that walking is the best form of exercise, for both men and women, and across all age groups. Walking exercises virtually all parts of the body, from the feet and calves to the back, arms, lungs and the heart. It is the most natural form of exercise, and does not carry the associated risks of jogging or strenuous exercise in a gym, and is a lot less expensive.
But what if you are one of those many people who can't enjoy walking because it causes sore feet, leg pain, back pain and uncomfortable posture. Maybe your children do not enjoy sports at school, again because of foot problems and lower back problems. In these situations you need to look at orthotics.
Orthotics are orthopaedic devices designed to treat or adjust various biomechanical foot disorders. They may be simple, commercially made devices, such as cushioned heel cups or insoles for shoes, but the best ones are insoles designed by doctors that give the user some form of personal adaptation of the insole.
Because perfect feet are very rare, almost anyone can benefit from orthotics. There are several common symptoms that may indicate misalignment of the feet. You may be a candidate for orthotic devices if:
- one side of the sole of your shoe wears out faster than the other;
- you frequently sprain your ankle;
- you have chronic heel, knee or lower back pain;
- your shins hurt;
- your toes are not straight;
- your feet point inward or excessively outward when you walk;
- your feet hurt in general.
While ?perfect feet? may be very rare, there is no such thing as an ?average foot?. That is why Walkfit Insoles are much better than an over the counter insole. These insoles are designed by physicians and they come with three different inserts, Low, Medium and High, to insure that they are suitable for your foot. You are advised to experiment with the inserts, for about 1 hour per day, until you find the one that is best suited to your needs. They also come in a large number of different sizes to suit men, women and children.
When using these insoles, remember that your shoes may have extra layers already in them. It is advised to remove these layers and just use the supplied insoles. Insoles are not like an instant painkiller, so be patient. It could take up to three weeks to adjust to these insoles but once you do, then you will realize the huge difference they make to your walking and exercising. You will then be able to partake in the healthiest form of exercise available to you.
