In the 70s, while learning sailing, I was taught to use a double half hitch, where the two hitches are tied in opposite directions. However, in the 90s, I took a USCG course, where in the same situations I was taught to use two half hitches, where the hitches are tied in the same direction, similar to a clove hitch.
For example, see this image from this scoutpioneering.com post, where they call my "double half hitch" a Lark's Head, and "two half hitches" a Clove Hitch:
I should have asked the course leaders, but never did: is there a valid use for a double half hitch/Lark's Head? (It's the version I always tie, although it does seem to work free when intermittently loaded.)
