On our L400 the guys run through standing blocks on each bow, then back along the deck
to standing blocks near the toe rail next to the winches. We have made these lines 25m long to allow them to be run out a long way in order to depower the spinnaker
when it comes time to douse it with the sock.
We initially rigged our symmetrical spinnaker with 2 guys and 2 sheets
but found it much easier for short handed cuising to go to one guy and one sheet. If the spinnaker needs to go over to the other side, we sock it, swap the lines from being a guy to a sheet, and vice-versa, then release the spinnaker.
Dousing the big kite in a fresh breeze with 4 lines attached with only 2 people was a bit of a handful. We had lines overboard
a couple of times a tangle around a rudder
. The spinnaker became known as "the Kraken". This beast is much tamer with only 2 tentacles.
