leaving from raft situation
In most cases we are preaching to the converted, those who would benefit the most from previous usefull comments won't be reading this forum!
What I would add but is:
As an inner boat leaving a raft, leave one of your crew on the raft while you stand off with your own boat. This allows the raft to settle and lines to be adjusted etc. Then come back in and assess the way the raft now sits and advise your crew member accordingly if further adjustment needed. Then pick him up of course!
