The deadrise is the angle between the horizontal and the "vee" of the boat measured at the transom. The higher the number of degrees, the deeper the vee and the smoother the ride in choppy water. A 16 degree deadrise hull would be described as a Medium Vee. For example. if you are after peak performance and handling then a deeper vee (say around 22 degrees) will be superb. This would however, affect the shape of the boat and you may have to give up some interior space to achieve a more arrow-like style
It wakes you up in the middle of the night, doesn't it?
And it doesn't do anything cos you've probably got the cold shoulder, and you don't know why but it usually has something to do with boats, cost of boats, not doing the garden,being a drunk, and knowing more about navigating the coastline than her bodyline.
As Pauline says a deeper V meens a comfier ride.
Measured at the chest, the higher the degrees to perpendicular gives a more satisfactry performance.
Flatter versions give a more bumpy ride and are not as effective at raising the dead. Hence the name Deadrise
Usually measured by the prefix A flat B,C and Deadrise!!
