Subject: [IC27A] Re: Way Too Much Tension on the Halyards Under Load - Please Advise
Thanks for the responses:
The halyards aren't showing any excess wear (that I can see). Is there any way to check if they are binding to electrical cables or themselves without unstepping the mast? Is there a way to tell if the hole in the sheave is elongated without taking it apart; ie would it wobble a little when I spin it? I have no idea when or if the sheaves have ever been changed. There are two spare sheaves (one on either side of the ones currently in use) to which I could switch.
Thanks again for the help.
Michael
