Quick Answer
In extreme conditions, use a storm trisail under the forestay to prevent knockdown or capsize, and to stabilize the boat's angle of attack. This is often more effective than hoisting a jib, as it helps to maintain a safe and consistent course.
Choosing the Right Sails for Extreme Conditions
When facing heavy weather, the choice between a storm trisail and a jib can be crucial. The forestay trisail is a dedicated storm sail that is specifically designed to withstand high winds and rough seas. It is typically a small, lightweight sail with a high aspect ratio and a deep clew, which allows it to generate maximum power while minimizing the risk of over-torqueing the mast.
Setting Up a Storm Trisail
To set up a storm trisail, start by securing it to the forestay using a dedicated trisail sheet and a storm trisail clip. The sail should be sheeted in tightly to minimize flapping and to maximize power. When the wind is above 30 knots, it’s essential to keep the sail tight and to maintain a consistent angle of attack to prevent the boat from heeling too far. A rule of thumb is to keep the sail sheeted in at a 45-degree angle to the wind, which will help to stabilize the boat and maintain a safe course.
When to Use a Jib
While a forestay trisail is often the preferred choice in extreme conditions, a jib can be used as a secondary option. However, it’s essential to use a storm jib with a high clew and a deep luff to maximize power while minimizing the risk of over-torqueing the mast. When using a jib, make sure to keep the sail sheeted in tightly and to maintain a consistent angle of attack to prevent the boat from heeling too far. It’s also essential to keep an eye on the weather and to be prepared to switch back to the storm trisail if conditions worsen.
