The following article first appeared on the Jeanneau Owners Forum
The following is a valuable photo-guide from Martti an SO29.2 owner from Finland on how to make this useful knot when attaching a shackle to a halyard. Whilst not as good as a splice, it is used by many Jeanneau dealers when commissioning.
The knot seems to have a variety of names but "Halyard Hitch" seems to be the most common. Below the images is useful video.
