450: Need length of spinnaker halyard

[Builder G.]

Hello, I was inspecting my running rigging before I depart with the homeward bound flotilla back to main land USA. I found chafe on the spinniker halyard as it comes over the block at the top of mast. My vessel is a 2011 lagoon 450 fly. Can anyone help with the length. Second question has any others seen chafe at the same location? Thanks in advance.

Have found the length. Thanks! Still interested if any owners have had the chafe in the same place.

Are you sure the chafe was at the top block and not the swiveled block that directs it down away from the mast? Ours chafed there as the swivel had seized and when the code zero was out to one side the halyard was rubbing against the metal surround for the block.
