[Rhodes22-list] Solar Mooring Light & Mast Crane

[Arthur H. Czerwonky]

Mike,
The mast sway can be the fearsome factor.  The 10" extension chains are meant to minimize, although most effect when the mast in nearest to the mount at the stern.  I have located my newly designed stern mast roller to be 27" above the transom top.  At that point the chains are mostly extended.  The only way to keep the sway near zero is like Roger Macgregor instells - the center point of the mast 'restraints' must be aligned with the point of pivot of the mast.  I'll expand if you really get that curious.
Wow, I really would discourage raising or lowering the mast by hand.  Some kind of mechanical assist should take the worry out - exactly why Stan designed the crane.  What if you hit a snag.  Ed brought up the gin pole many weeks ago - all I have ever used, myself, for many years.  Luis used the manual system and was lucky he didn't lose a substantial investment in his mast - some just can't be fixed.  
I don''t think the crane applies any unmanagable stress to the tabernackle.  Drop the mast and you will for certain.
I dropped and raised the mast by myself this afternoon.  It's a swish.
Chow,
Art
