Sailing is a Pleasure of Life-An Overview

Sailing Performance

Sails today are vastly different from those that existed prior to the polyester revolution. The most important aspect in sail performance has always been shape, and time was when you picked the best canvas for the conditions, pulled it up, and sheeted it in. This is how some cruising sails are still built.Do you want to learn more? Visit

They function adequately, but the fabric from which they are made also ensures that their performance potential is much inferior to that of a modern sail whose geometry can be adjusted to accommodate the wind and sea. Following the lead set by sailing yachts, such technology has found its way into cruisers, whose hi-tech vanguard has now advanced to cloths of such complexity and stability that the form cut into their sails is hardly threatened before they simply break.

A sail’s highest camber should be just ahead of the centre of its cross-section. In fact, this depends depending on the type of sail and how strong the wind is blowing. Since the strength of an aerofoil is proportional to its curvature, a baggy sail can propel you along in light winds much more efficiently than a flat sail. The fullcut sail’s strength will become too big for the boat as the wind gets heavier. If flattening or reefing is feasible, it must be done; if not, it must be replaced with a new sail.

The idea that a sail inherently gets fuller as the wind rises and the point of optimum camber is blown aft onto the leech reinforces this criterion. All of these consequences are unacceptable, and more has to be done to minimise them.

There’s also the issue of twist to consider in addition to camber power.

In their upper parts, most sails curl away from the wind. This propensity is intentionally programmed into them, and it can be harnessed to your benefit.

For many sailors, twist is a closed book, but missing it can dramatically reduce your boat’s pace. The explanation for this is that the wind sails more aloft than it does near the deck because surface contact with the sea slows it down. When a boat sails across the water, the breeze she feels is a composite known as visible wind. She may be propelled by a real breeze from behind her, but she’s still creating a phantom breeze from straight ahead, blowing in the opposite direction to her own movement through the air.
