[alberg30] Sling positions

[Bob Lincoln]

From: Bob Lincoln <lincoln at cc.UManitoba.CA>

Further on sling positions when lifting; do both straps need to be on the 
keel bottom, or can the forward one sit in the keel cutaway?  I suppose 
this would tilt the boat forward when raised.  Is it safe to lift the boat 
slightly with the rear strap aft of the keel?  If the boat had been lifted 
from this aft spot, would it stress or crack the rudder shaft or rudder? 
 It seems that the full keel can't rest along its entire length because 
then there would be no spaces to slip a strap under it.  I suppose blocking 
the keel would get around this.  Unlike a fin keel it seems like the cradle 
pads would also get in the way of the rear strap when lifting.  Are there 
any simple solutions to this.  You can see I'm struggling with the centre 
of balance and the lifting strategy.  Thanks again.
