how is the halyard run for your (all y'all's) spinnaker?
does it run through a block on a crane at the masthead and external to the mast?
or does it run through a block on a crane and into the sheave on the mast and then inside the mast to the step?
or is it just through the sheave at the masthead, without crane and extra block?

currently i only have one halyard up there, which stays up all the time due to the roller furling. when i called a rigging shop about helping me out with rigging the spin, they told me that it was going to be quite complicated, crane, external block, and external halyard.

any thoughts?
thanks
