Re: Lift Points (Deck Penetrations for Sling) & Unstepping the Mast

Several of the sj24 at Leschi including mine are rigged for a single  
hoist lifting bail going thru one 3" hole in the hole in the cabin 
top. I have a sling system that attaches to two permanent stainless 
brackets attached to the keel bolts.
If you happen to come by Leschi you can take a look at my set up. It 
has worked well for many years and it is plenty strong enough to lift 
the 3600lb +++?
