Masthead, multi-spreader rig, in-line spreaders, deck-stepped mast, forward and aft lower shrouds. Alternatively, baby stay and aft lower shrouds.

At the crane • Read the “At the crane” section on pages 20-21. • Lift the mast and place it on the T-base. • Attach the cap shrouds, backstay, forestay and all four lower shrouds. • Tighten the cap shrouds, forestay and backstay hand-tight so that the mast is stayed both laterally and longitudinally. Attach the lower shrouds.• Lower and remove the lifting strop. Move the yacht away from the crane. This type of rig is often fitted with an inner sail-carrying forestay, a cutter stay. The location of the cutter stay deter- mines whether “running backstays” (also called “runners”) are needed to provide sufficient longitudinal stability as well as to provide the necessary cutter stay tension. We recommend runners if the cutter stay is attached more than 6% of the fore-triangle height below the ordinary forestay fitting.
Cap shroud15% Backstay 15% Tuning • Check the mast rake. Adjust if necessary using toggles on the forestay.• Tension the cap shrouds to 15% of the breaking load of the wire. See the “folding rule method”, page 29. • Straighten the mast using the forward lower shrouds and the intermediate shrouds. If necessary, adjust the rigging screws for the cap shrouds without changing the cap shrouds tension (slacken one rigging screw by exactly the same amount as you tighten the other one). Check that the mast is straight by sighting up the luff groove, all the way up from deck level.
