Welcome to the forum Gentleannie, it would really depend on the experience of the Captain
and crew, the more experience the less talk is needed. Most experienced folk have a talk about the docking
and what to expect from each crew member
before arriving. If you all have been working (sailing) together for years then you pretty much know what to do when. If you all are new to each other and the boat, then it would be helpful to have headsets, I have read in this forum how some folks find the head
sets useful when setting the anchor
, picking up a mooring
and or docking, so they have their uses. Depending on the situation you might be able to just use hand sets, they come fairly inexpensive these days.
