Thanks for the responses.

Kite shaped sail is literally like an inverted childs kite, diamond
type of shape. This sail could possibly be 35 years old if that
provides any clues.

Very interesting points on the use of staysail, I'll give them a go.

The area we sail in often gets 1-2 week periods of 20-25,30 knt winds
during winter with 8-15knts more typical the rest of the year.

One idea I was entertaining was going with the furler and putting the
inner forestay on a hyfield lever to get it out of the way when
tacking. (thinking I wouldn't have the staysail up.) If the wind really
got too much I could completely furl the furler and use the staysail
only. ie forget about the yankee cut jib altogether.

I guess experience on my boat will tell me this in time but in your
experience would the benefits of a staysail with genoa make the above
idea a bad trade off?

And lastly (this one puzzles me) if caught in a gale I understand you'd
remove the furled sail. ie leave the forestay bare. Is this correct? I
had a bad experience where a poorly furled jib developed a pocket 3/4
up and flogged to shreds.

If so how do you go about removing this sail when you furled it because
the winds were overpowering it in the first place.

So much to learn.
Thanks again
