[Rhodes22-list] Topping lift

[Hank]

Slim,

The rescue harness you're thinking of is the Life Sling.  A very good
product and easily used and deployed.  I have practiced with it on my
Islander 36 and we did use the boom with the vang attached to a padeye
near the end of the boom.  It worked very well.
