Topic: Wanted / Bosun's Chair or some way up my mast

I need a way up my 40’ mast to rig a spinnaker halyard:

a) I’ll buy your bosun’s chair b) I’ll rent your bosun’s chair c) I’ll borrow your bosun’s chair d) I’ll accept any other advice or methods to get up my mast.

My boat is in Alameda. Thanks!
