![]() Again, to see the planform would be better, as now I'm just trying to imagine the waterlines in my mind according to the other 2 views, so I may say something wrong.Ġ.39? those guys with the weird paddle push really a lot then, I thought the dragon boats were much slower. However your hull looks more streamlined. ![]() But maybe they're overloaded (I count more than 30 people, while you said 22) or with a bow trim. The yellow boat in the photo has an horrible blunt bow/stern which makes a lot of form drag. When I asked about the waterline I meant the planform (top view). Well, I don't envy you in figuring out this task. ![]() So what's the influence of all the paddles? ![]() That is the theoretical 'ideal' condition, but in this case it looks quite far from the real case according to the picture of the yellow boat. If you run Leo's code, I guess (I didn't try it myself, but it should be) one of the output is the wave pattern, and at that speed you should notice a clearly defined wave along the hull. At this Fn then the wave resistance isn't neglectable imo, it should be around 20%-30% of the total (just my rough guess).Īnyway, looking at the picture that you posted i notice also that the crew is paddling all along the hull, doing a lot of mess on the wave profile.
