Rigging the Gennaker Sail

This section describes the rigging that is done in readiness for each sailing session assuming the Gennaker is stowed away from the dinghy when not sailing - it assumes that the Standing rigging for the Gennaker is in place.
 
1.    Before the mast was raised the the free block on the Gennaker halyard should have been fastened to the ring at the front top of the mast using the ‘D’ shackle. If the Gennaker halyard is terminated in a bobble the halyard will already be threaded through this block. If not thread the Gennaker halyard through the block and temporarily tie off at the ring on the base of the mast. Raise the mast (see ‘Raising the Mast’).
 
2.    Find the Tack of the Gennaker (helpfully marked ‘T’) and attach the Tack line emerging from the front of the Bowsprit pole using either the bobble or a half hitch with the overhand knot acting as a stopper. Make sure that the knot is not holding the Tack of the Gennaker in a twisted position.
 
3.    Run your hand up the Luff of the Gennaker to its Head (helpfully marked ‘H’). Keeping the Gennaker luff untwisted release the Gennaker halyard from its tie off and fasten the bobble to the Head of the Gennaker, or alternatively use a bowline knot.
 
4.    Find the Clew of the Gennaker (marked ‘C’). Find the centre of the Gennaker sheet by folding it in two to form a loop. Pass the loop through the clew cringle (eyelet) and pass the tails through the loop.  Ensure the ‘Larks foot’ knot so formed seats as smoothly as possible around the clew. Thread the respective sheets through the port and starboard ratchets in the correct direction but as you do so make doubly sure that the Gennaker sheets are outside the Jib wire and the Gennaker hoisting/downhaul line. The gennaker ratchets are so-called automatic ratchets. The ratchet action only comes into play when significant tension is applied to the gennaker sheets. Pass one end of the gennaker sheets into the gennaker ratchet block, makiing sure that you follow the direction indicated by the ratchet arrow. Test for the correct direction by threading the sheet around the ratchet and giving a good pull on the sheet in either direction and you will hear the ratchet action operate. A natty refinement most useful in strong winds.  Finally either tie the sheet ends together using a Fishermans knot or tie a stopper knot in the end of each, whichever you prefer.
 
5.    Attach the Gennaker downhaul. This is the line that emerges from the front mouth of the chute, ie is normally tied off around the furler unit for storage. It needs to be connected to the Gennaker patch fastenings.
Two important points to note when threading the downhaul line.
   i    Make sure that the downhaul line is inside the Tack line and not looped around it in any way (if the Gennaker downhaul is tangled with the Tack line the Gennaker may be twisted when it is launched).
   ii.    Ensure that the Gennaker downhaul line is within (to the front of) the Gennaker sheets. If the downhaul line is inadvertently threaded to the rear of the Gennaker sheets pulling on the sheets to start a gybe will also partially pull in the downhaul line.
 
6.   After checking for the above problems thread the downhaul end upwards through the Gennaker lower patch cringle. At this stage slide on (not tie) a bobble with its smooth side downwards (this is to prevent the bowline knot used to attach the line to the upper webbing patch from jamming in the lower patch cringle). Finally use a bowline knot to tie the downhaul line to the webbing strap of the upper patch in the Gennaker.
 
7.    With the Gennaker sail fully rigged it should now be possible to pull the Gennaker into its chute using the downhaul line. When correctly packed in the chute the Tack, Head and Clew cringles will be visible in the mouth of the chute.
8.  Finally do remember to tape up the shackle linking the Jib wire to the Furler unit. It is all too easy for the Gennaker to snag on this link and, in the worst case scenario, the gennaker may drop under the boat, fills with water and the force of a speeding boat will easily rip the delicate gennaker fabric.
