A storm jib is great when there's land to the lee but the ability to travel upwind is by no means confined to that. For example, running off could lead the vessel into a dangerous part of a big depression in circumstances where clawing up to windward is a route to safety.
What is a Storm Jib and How to Use One. A storm jib is familiar to most sailors and can be a very useful addition to the cruiser’s sail plan as it offers a robust, useful headsail that can usually be relied upon to combine well with a reefed mainsail, a tri-sail or even a mizzen sail to provide a stable and effective sail plan in anything over say ...
A storm jib is much smaller than the regular jib, so as to reduce the wind force to a more manageable level while still providing propulsion. The storm jib is also cut with a high foot, so that a sea washing over the prow doesn't push it back.
Because the storm jib is a short luffed sail as well as a small one if it is rigged too low to the deck it could loose power in the wave troughs, leading to the boat losing steerage way and all the difficulties of that when it comes to steering the boat effectively up and down the waves.
People worry too much about a storm jib being to far forward and causing lee helm. In the sort of weather when you are under storm jib only you are usually heeling enough to create heel-induced weather helm that balances it out. And area for area a small headsail is much more efficient than a similar sized sail behind a mast.
As a first step, adjust the jib’s tack pennant, a length of sturdy line or wire bent on to the tack of the storm jib that allows you to raise the sail up off the foredeck so that waves can wash under and not into it. How high you should raise the tack depends upon the size of your boat.
Although the wind dropped during the course of the day, it remained brisk enough to present us with a challenge and allowed us to return with some firm convictions about which types of storm jib make the most sense. Wrap-around storm jibs. A popular solution for those who use a furling genoa, a wrap-around consists of two identical storm jibs sewn together at the luffs. The tack is made fast to the furling drum, the head to a halyard, and both clews are attached to both sheets.
I guess I took the word jib in “storm jib” to describe a small headsail. I was wondering how that would do anything in storm conditions but to force the bow off the wind. I get now that the “jib” is a sail mounted in the “middle” of the boat providing some power and steerage capability. Not sure what you mean by warp ??
Being designed and made for tough conditions, storm sails will set better, perform better and be stronger and thus safer than deeply reefed sails. Especially if the storm jib is set on a dedicated inner forestay, the sail configuration of storm jib and trysail will concentrate the centre of effort in the middle of the boat.
The storm sail or jib attaches to an inner forestay, which is removable if necessary. Some sailors use a flat-cut headsail as a storm sail and others a reefed roller genoa. The latter is generally not recommended.
