I hope I can find some of the information that has been gained in the last 30 years, at a layman's level that I might understand. I've read some good points on this thread, like the fact that with wood, they could not build a strong fin keel like we can with modern materials. Also, today's better understanding of airplane type wings (keels) and their ability to generate lift.
Regarding standing up on a 27ft boat, probably not the best way to increase seaworthiness, but related with what I said in the last post I will post in the interesting sailboat thread a boat that taking into account what was learned in 35 years of Transats on minis (including a non stop circumnavigation), is proposed as the prototype of the (very) small offshore fast boat.
