Re: series drogue or para anchor?
I guess what I'm trying to get at is that if a hull is viewed from the bottom, it seems like most of the boats that have proven records of long distance voyaging have a pointed entry both bow and stern even though not identified as double-enders. Even the narrow CCA era overhung boats like my old A35 "split" the water dissipating the wave energy on both ends. It's definitely true that there are fewer and fewer true double-enders around but it's usually apparent that they actually voyage somewhere rather than sitting tied to docks with a canvas tent over the cockpit.
