who can explain to me what this means and what should it be for an inshore or near shore boat?

If I am not mistaken, deadrise technically refers to the upward slope of the deck of a boat. Or how much "rise" there is from the drain point to the highest point per foot. I have no idea what it should be though. I have also heard it used to describe the angle of the Deep V at the Bow. The steeper it is the better it cuts through the waves and the less stable it is at rest. Hope that helps.

Deadrise is the angle the hull slopes upward from the keel to the base of the gunnels, measured in degrees. the lower the number, the less angle, and vice-versa. as far as what it "should be" all depends on what kind of fishing you will be doing.
a boat with a deeper v will cut through the swells better, but will roll more. a boat with a shallower v will not ride as good, but will be more stable in a beam sea.

Take mine for example. I have a 24 degree deadrise. This makes for an excellent ride. Manufacturer has added 22 degree outer skegs and added 6 in. more to beam to make it a 9ft. wide beam. This is for stability. I don't have as much roll as contenders or Regulators but I have more roll than a Kencraft. I can run alot harder with better ride than Tritions and Hydrosports. If you have an average of 17 degrees then your ideal speed in 2-3 ft seas wil be 17-20 mph. My average speed in same seas is 30-34 mph. with a comparable ride.

Deadrise is the angle in degrees from the keel to the chine. (usually) measured at the transom. :)

if you want to see a perfect example of deadrise, go find a maycraft (10degrees deadrise) at the rear, 29 degrees at front. notice the v is less at the rear compared to hulls with higher degrees of deadrise. as mentioned in previous post, they don;t ride quiet as smooth in rougher water as deeper v hulls but are very stable at drift.you can;t have it both ways however they don;t ride as bad as one would think.

Simply...0 degees, flat bottom. 28 degrees, damn near a knife edge. The steeper angle will slice through the waves as a cigarette type boat, giving it a much smoother ride at speed, but this boat will roll like a teenager at a rave when she is dead in the water. Piss poor fishing platform, eh? but, a go fast is not designed to sit. A carolina skiff on the other hand is the perfect stable platform. Underway, however slams down on each and every wave and therefore not practical for offshore use. unless of course you have a grudge against your kidneys and enjoy pissing blood.
Measured at the stern an offshore boat will have much less of a deadrise than toward the bow at the deepest part of the vee or POINT OF ENTRY. Manufacturers are constantly playing with this design or that trying to come up with the perfect hull design. but, its all a trade off. Deep vee at the bow while under way, lesser at the stern while she is at rest.
