I removed various lines for washing the other day and now have to refit them. Things like the kicker and mainsheet were attached to the block by a knot that I didn’t recognise, but it seems to be the standard method employed by Opal’s rigger for such things. The nearest thing I could find in a reference knot book was a buntline hitch but it has an extra turn. I’ve done my best to replicate the knot and it seems to work. Has anyone ever heard of a double buntline hitch, or am I missing something completely?
