[UK-CONTEST] Gin Poles

[Mike Farmer]

Not true Roger.   But very wise to point the potential for disaster out.   I
hit  a slope that was 3 feet higher on one side in Singapore.  Bit of trial
and error with just the derryk moving it from ground to vertical and back
allowed side guys adjustment and once that was done lifting the main mast
and adjusing the main side guys every 3/5 feet of lift got it airboure -
took a lot longer but was still single handed.
