The nautical term "fetch" apparently has at least three different meanings. I take it that in this context it means "a distance over the water that the wind has to build up a wave pattern". Can I eyeball the average speed over that stretch at about 12 knots ?
i have the impression that many boat watchers are bow watchers. Until dolphins appear. The contrast between your video and the one earlier showing the praocargo cannot be more different. As an expert water flow watcher yourself is there some advice to amateurs to correct the frame of their intuitive interpretations of water moving about the bows?
In the same vein estimating wave height seems to do little justice to the rather complex statistical parameters used in the physics of waves. What are the heuristics that you use as being the most practical?
The well of the ww hull is essentially horizontal. So the the interaction with waves is boolean: they reach that height or not and until they do the boat profits from the slim hull with straight sides. A more classic hull with outward sloping sides balances out the relative disadvantage at low wave heigth with the lack of disruption at wave heights up to the height of the beams. With this hull form the waves are parted sideways while with the classic HP form the waves are slammed down. Intuitively the former seems less disruptive than the latter with a more comfortable ride. I also notice evolution on the design of the sides of the stabilizing parts of your V13 and the difficult choice of the height of the sole of the deck. Of course, this is a very different boat but I guess that some of the reasonings that went into the decisions taken there are also at work with HP planform boats.
