Halyard routing

The routing of halyards is always important, but particu-larly so on yachts with jib furling and reefing systems. A properly installed halyard box provides optimum hal-yard routing. Seldén offers a complete range of halyard boxes. You can choose between our range of single- or
double halyard boxes shown in the table on the next page.
You can also use halyard leads (see below). Seldén halyard leads are made from chromed bronze, so that the relatively soft bronze will not damage a stainless
steel wire halyard. The halyard leads are easily retrofitted
to an existing mast.On yachts with furling systems, correct halyard routing ensures that the halyard does not wrap around the fore-stay extrusion when furling the foresail. Sheave boxes, slot fittings
