......family boat (that he loved) the Pen Duick, an old and beautiful old full keeler.
Paulo, thank you for the further details on the wave motion etc. I especially like the photo of the Pen Duick, wow! Those old style low lean boats thrill my blood. I have to say new boats look like they sit on top of the water in the wind, while the old style seem to knife through the water.
Nevertheless, I like the way I can stand up in a modern 27 ft. boat, instead of having to increase size to a 40ft plus boat. So I'm casually looking at more modern boats with headroom in the smallest size that will sail well. They all have fin keels.
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.
