Find your emergency tiller
Yep, I can attest to the benefits of knowing where the emergency tiller is stowed, and how it works, as I had to use it recently when I lost my binnacle in an accidental gybe (see the ''boom preventer or not'' thread).
As we have new crew fairly regularly on our ocean races, I typically walk everybody through the emergency procedures and gear for about 10 min as we motor out towards the start. That includes flares, emergency tiller, MOB stuff, and location of knives to cut lines/halyards, etc.. I think it really does pay off, since in an emergency, most everyone knows what''s where, and things not just go faster, but there''s less stress, which I think is nearly more critical than the speed issue.
