... when you go about the headsail moves across from one side of the boat to the other on its own.
There are no winches to grind. And there's no rushing around deck on whilst tacking
Tacking Cool Change is as easy as turning the the wheel!
The obvious advantage of a self tacker is that it makes it incredibly easy to sail.
It's no problem to sail single-handed or with an inexperienced crew.
The smaller headsail does not get caught and damaged on the guard rails so it lasts longer.
And there's no more heading up front to skirt the sail.
Now what about performance?
Does the Smaller Headsail Result in Compromised Performance?
... not when the self-tacker is part of the design from day one.
On Yachts designed with the self-tacker in mind, it is part of a high-aspect rig with a large mainsail. In addition a smaller headsail offers a better shape... the jib is flatter so the yacht points higher.
When tacking you don't need to let go or even loosen the jib sheet. This means the jib sheet stays taught and there's minimal flapping of the sail.
...speedy tacking with no fuss at all!
On Cool Change, my Moody 45DSe the self-tacking headsail is intrinsic to the overall yacht design as opposed to an after-thought option.
Moody boats are designed with the mast stepped further back and a high aspect rig plan.
This means a beautifully balanced yacht that's easy to sail.
With a self-tacker you have just one jib sheet.
The sheet goes from the clew of the sail to a stand-up block mounted on the self-tacker track (see picture).
The sheet then feeds up to the mast, back down inside the mast and back to the cockpit winch.
When tacking the block simply slides from one side to the other as the bow goes through the wind.
Look at the You Tube video to see how simple it works.
