Ya, that picture was great, wasnt it?

Mule sail: here comes everything I know, which aint much.

Three cornered sail for ketches similar in design and function to the four cornered fisherman sail used on schooners, and at least in terms of romance (to me), to the gaffs topsail.

The head of the sail is raised to the aft of the main masthead, the foot tacks to a bracket at the lower, leading edge of the mizzen (above the intersection of the backstay), and the clew is sheeted toward the top of the mizzen. Emphasis here is that the corner of the sail that points at the head of the mizzen is the under-sail adjustment pointthus the reference to clew / sheet.

Typically the luff HANKS onto the backstay, a thing not possible with our split backstay, but Ive hoisted my storm jib a few times as mule and as experiment, and I dont think hanks are at all necessary.

Yes, a light or lighter wind sail that will only draw well with wind on the beam and forward. Its not very big, so it wont provide whopping power, but its up high where theres more wind, so is likely to deliver far more push than a staysail of similar size.

Im attracted to it because it will be dead easy to raise and lower, as opposed to the much more powerful but finicky mizzen staysail. I love the idea of the mizzen staysail, but deploying it is like wrestling a ball of yarn away from a cat, and just when its balanced perfectly, its time to tack.

I intent to install the hardware for one this winter, which will be a tang and block at the after end of the masthead rig above the backstay but below the triadic (probably under the triadic swage and pin point), a similar tang and block at the leading edge of the mizzen masthead, and a bracket further down. All pretty straightforward, I think.

The mule has the reputation of being only for looks, but my small experiments suggest it has plenty of kick where its neededand it does look great, an added bonus!

Do you need to weld on another attachment point on the main masthead? Or can you simply put another tang on the same pin with the triatic? Will you use the mizzen staysail halyard as the sheet for this one?

I've not done this yet, so this first answer is tentative, but

***re attaching tang to the triadic pin, I dont think so. I had a look at some photos I have of the masthead rig, and my original thoughts were wrong. The triadic stay connection is a fork end, so I dont think attaching a tang there would as smart as attaching to the TOP of the backstay bracket in essentially the same way the topnlift is attached. See photos.


***re mizzen, yes, the mizzen staysail halyard is the sheet for the mule or rather, the mule sheet is the mizzen staysail halyard--take your pick. :)

I dont think a weld on the bracket is necessary.
