09 – The Simbo Rig without whisker poles or need of foredeck work. Note the true wind angle from the ensign, compared with the apparent wind angle accelerating off the mainsail from the courtesy flag

10 – The leeward whisker pole secured by a boom lift plus fore and aft guys, the jib sheeted by a red running sheet. Its lazy blue partner crosses via the weather pole in preparation for sailing on the wind
