If you speed up, the bow wave goes faster. If you slow down, the bow wave slows down. How do you climb a wave that you are making? If climbing a wave was the cause of the resistance, the force increase would be proportional to the slope. However, the slope doesn't increase at the rate which the force increases. Hence, it's highly unlikely that the resistance can reasonably be said to come from climbing your bow wave. You can't (first paragraph) and you aren't (second paragraph) in spite of the claims of so many. The reason the the force increases is that you're pushing a lot of water around.

With all this discussion on hull length, I am wondering why skeg design tends to opt for depth as opposed to increasing waterline length- kinda poking out the stern more on the surface? -- ¤ Gabriel L Romeu ¤ http://studiofurniture.com + /diary or + /paint *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).

Waves! If you have depth forward of the stern, the skeg is more likely to stay in the water when you are going over waves. At the stern, it would be lifted clear as your bow dives into a trough. This is one of the drawbacks with rudders used to control weathercocking.
