[Public-list] Boarding ladders & engine lifting

[Mike Lehman]

David,

That's how we've been removing engines from the Alberg for a long time. You 
can use the boom to lift the engine and swing it over the side. You should 
attach a halyard to the boom at the same point as you attach the come-a-long 
so you do not bend the boom in halh. The attachement point is right over the 
main companionway and you can lower the come-a-long right down to the engine 
a pick it up that way. It will want to swing forward a bit to clear the 
bridge deck.

Changing the topic slightly, would it be possible to use the technique
described below (the boom and sheet can be transformed into a lifting
derrick) to lift the Atomic 4 engine out of the cabin and land it over the
side?
