Recore deck around chainplates.

[monocerosin]

Since the mast is keel-stepped can I remove all the shrouds or do it one side at a time?

use halyards as a temp support, and only disconnect and service one shroud at a time. Cap shroud will be fine gone with temp support, forward and lower in the mix.

edit: i misread, this is core, not bedding replacement: best to pull the mast if you can so you can attack the whole area. Otherwise temp support is still recommended.
