Make a whipping on the end of double braided ropes to keep core and cover together.
A tapered Genoa Halyard on the SJ24 will reduce the effort to hoist the sail. Make sure to select a double braid line that includes UV protection of the inner dyneema core.
A Brummel Lock-Splice is great for providing a dyneema eye loop that won't slip. Perfect for the Genoa Halyard.
This technique is required if your line is run through the mast or the far end otherwise inaccessible.
This technique is not commonly used anymore on small boats.
