Initially I was determined to have a cutter rig on Aventura IV, but was eventually persuaded that a fractional rig with swept-back spreaders would be more efficient than a standard cutter rig. Indeed, the Solent jib performed very well when close-hauled and the mast was also much better stayed than on the previous Aventura. But I still insisted on a split rig, with a staysail set on an inner forestay to be used in stronger winds. It was a good solution and reinforced my conviction that the flexibility provided by a two-foresail configuration is a major advantage on any boat over 40ft.
While setting up the running rigging it is a good idea to have a close look at the existing deck layout and the run of the various sheets and lines, which should have a clear unobstructed run back to the cockpit helped by turning blocks at critical points. As to halyards, the mast should have enough dedicated channels for spinnaker and foresail halyards, and their backups. On Aventura IV, the mainsail halyard was of Dyneema non-stretch material and I decided to have the boom topping lift from the same material so as to have a permanent backup for the mainsail halyard. I always prefer to have two spinnaker
