  2. Battened Mainsail : 4 Things to Check Before sailing (T017)

Hello, and thank you for joining us for this new Sailhero tutorial.
Are you heading off on a cruise with your boat soon? Before casting off, it’s important to check the condition of your battened mainsail.
Today, we’re going to show you four essential things to check before setting off on a cruise. Let’s get started!
1. Inspect the fabric of your mainsail
Hoist the sail completely and carefully inspect the entire surface.
Look for any tears, cuts or areas of wear, particularly where the fabric may have rubbed against the rigging, such as the batten pockets.
An ageing sail can also gradually lose its strength and shape. Check that the fabric does not have deep creases or areas that have been crushed or improperly rolled.
If you find a tear or a weakened area, it’s better to deal with it before departure rather than discover the problem while sailing.
2. Check the stitching
The stitching provides the sail with its strength, but it can become weakened by UV exposure, salt and repeated loads.
Inspect the stitching carefully and make sure it is neither frayed nor broken.
Pay particular attention to the most highly loaded areas, such as the head reinforcements, clew and tack.
If you notice a broken thread or stitching that is starting to come undone, have it repaired before departure. A small preventive repair can prevent a seam from failing under load during your cruise.
3. Check the battens
Make sure that all the battens are properly installed and correctly tensioned.
A poorly adjusted batten can create wrinkles in the sail, make hoisting more difficult or cause premature wear.
Also inspect the batten ends and batten pockets for any signs of weakness or tearing.
4. Check the cars, slides and hardware fitted to the sail
Make sure that the mainsail cars or slides run freely along the mast.
Check their general condition, including the pins, wheels or sliders, depending on your setup.
A clean system in good condition makes hoisting and lowering the sail easier, even when conditions become more demanding.
The reefing lines can also be checked once the sail is hoisted — both their condition and the consistency of the system.
Make sure that the ropes are not damaged or excessively worn.
In summary
A few minutes of checking before departure can make all the difference.
Properly adjusted battens, a functional luff guidance system and a sail in good condition will allow you to sail with greater peace of mind, with a reliable and efficient mainsail throughout your cruise.
Important: Make sure you are able to reduce the mainsail quickly if the wind increases, and don’t wait for conditions to deteriorate before doing so.
Before departure, test each reefing configuration that you might need to use during your cruise.
So, is your mainsail ready to go?
If you have any doubts about its condition, have it inspected by a professional before departure.
