Hi Matthew, hi Tony,
wrote a detailed response this morning but lost it all again frustratingly when trying to attach photos of the classic British Rowing Lifeboat, which had been inspiring me to the centre cockpit mod of the BRe. The design principle of the raised buoyancy at bow and stern in connection with low buoyancy midships is the key to unaided self-righting of all shallow draught boats, rowing or sailing.
Here at least are the photos in question.
