Running backstay attachments

Adding a cutter stay to a masthead rig Running backstays may be necessary if a cutter stay for a storm jib or staysail is fitted. Option 1: The cutter stay is located 3-6% of the height of the foretriangle below the existing
forestay. In this case, running backstays are not required to tension the cutter stay. Option 2: The cutter stay is located more than 6% of the height of the foretriangle below the
existing forestay. In this case, running backstays are necessary. The forestay fitting
should be fitted within 1000 mm of the spreaders, with the running backstays preferably
300-500 mm above. Whichever option is chosen, the amount of material cut out from
the mast may be over-concentrated in a small area. Please contact Seldén Mast for advice
on the correct fastenings and the correct location of the fastenings, as well as the hal-
yard control system. Conventional fittings for running backstays Backing plate including securing strap
