Tie the halyard to the end of the boom and sheet the mainsheet in firmly
Don't do this.
It will result in one or more of the following
1, Minimum the halyard will just streach and not really bend the mast
2, The halyard will streach a little and then break, possibly causing your mainsheet blocks to impact each other and (poss) crack, and or boom shattering after the shock of the release.
Do this.
Shackle one trap wire to the mainsheet via the boom and sheet in having set the mast rotation at the required level.
