Added some Japan drier... made a noticeable difference.
Did all the rigging at once and wow, does that brew stink.
(All my rigging is detached and draped over sawhorses in my backyard greenhouse. Great place to work when it's raining, but a little lacking in ventilation compared to outside.)
I'll try some varnish with the next batch, for the bobstay and whisker stays (or bowsprit shrouds, or whatever the heck they are), and lifelines.
