Reading a news item from the Congressional Cup 2008 I was reminded of an incident at the Match Race in Calpe. It also involved a broken spinnaker pole. This one was only damaged at one side and could not be fixed to the mast anymore, the other end was still working and could be fixed to the guy.
So with one end broken, the crew was holding the pole at that end, pushing the spinnaker outward. Rule 50.2 states that a spinnaker pole shall only be used when attached to the mast. Holding it is therefore only permitted if the broken end is connected (touching) the mast. A crew member can hold it there, but shall not push it outward. Quit logical, because that changes the area of the spinnaker.
What about not using the pole at all, holding the guy in your hands? Is that something which is permitted?
If you see a boat with a crew member holding the spinnaker pole, without one end touching the mast - other than briefly when setting or taking down - you must protest that boat according to C8.4. It is not an infringement that can be penalized by a colored flag.
