Topping lift

Is their ever a time when it is correct form to use a topping lift to change the shape of the main sail.

IOW: Typically a topping lift is used to support the boom when lowering or raising the sail.

But if it is tight with the sail up it will slacken the leech.
Is this ever a good thing and if so when.

If it is sometimes used that features is lost when a ridged boom Vang is installed yes?

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: Topping lift

Shorten the topping lift to add "depth" to the sail in light air.

Re: Topping lift

What Jim said.
Raise the topping lift in light air to increase draft, depth, curvature of the main.
Not for good air.

Re: Topping lift

As above, only if the weight of a heavy boom affects sail shape in near-calm conditions. Very rarely used in my exp.

Rigid vang could do the same if it is adjustable enough.

I guess you answered my real question. I knew it could be done I was just wondering if it was a common technique.

I did it a few days ago didn't remember doing it on purpose before.
Many time I've hoisted a sail and wondered why it was setting so poorly until I noticed the TL was too tight.

Well spotted, David. Most people don't notice that the topping lift is too tight until after they haul on the mainsheet really hard.. and something (usually, but not always, the topping lift) breaks.
