[Rhodes22-list] So about the centerboard

I agree with Mary Lou.  I do not recall seeing any safety lines used on 
slings.  That doesn't mean that it is correct or prudent to lift boats 
without such devices.  How many carpenters use safety goggles when hammering 
in a nail?  That may be why insurance rates are so high.  Of course, if they 
drop my R22, it will probably be "totaled" and the settlement would not 
cover a replacement.  In this case, insured or not, one might be wise to 
request safety lines to prevent the possibility of loss.
