Do you experience more mistakes sailing with crew on board than when solo? And more mistakes with more crew?
I do, and apparently so did Ted Turner when skippering for the America's cup.

yes winch overrides are a drama with inexperienced crew . But i must say that worst drama ive had was when i was alone ..... fatigue and lack of vision is a huge cause of mistakes !!!!
for every crew has another set of eyes , invaluable in close quarters sailing !!
On the the subject of crew It takes a fair while for a group of people to work well together as a crew and learn the idiosyncrasies of the gear on the boat
On the boat I race on we took about a full season before the 5 of us started to work well together and not long after this happened sickness and other commitments ment we lost 2 of the blokes
When we get new crew on the boat the mistakes by all seem to increase perhaps because you are distracted from your job when you are watching them and helping them to learn their roles

Yes, good points. I think a well-coordinated crew that knows how to work to together is invaluable, and mistakes happen a lot less. I don't race regularly, and probably don't practice enough, so my crew tend to have to relearn every time we do. When cruising, I tend to have a lot of newbies each time, and although I don't expect much from most of them, as you say, it's more distracting than when sailing solo.
Does Ted have a different equation for bringing boats into marina berths. I find this is one of the places things go pear shaped real quick with inexperienced crew. Most times I would rather they sat still with their hands in their pockets. Then they can see how it's done. Verbal directions don't work as well no matter how loud you say them.

Just thought I would put my original comments in context
Although experienced crew is great , I think that as far as racing goes a reliable learner is probably more valuable than a unreliable experienced person
If someone is prepared to turn up for each race they will soon get the hang of it and you don't have to go chasing crew at the last moment
We all had to start somewhere (I still make lots of stuff ups) and willing and reliable crew are hard to find
