22 hull specs?

I'm trying to compare another boat's hull to the C-Dory 22 (not classic) but am stymied when I search online for some of the specs.

I have found

Length 22'0"
Beam 7'8"
Transom height 20" (not an official spec; is this correct?)

I am unable to find

Inside depth
Deadrise forward, amidships & aft (in inches)
Side height

Can you help? Thanks!

Hi Warren:

My transom measures 20" (close enough)

Depth of cockpit to the floor (removable) is 32 " aft Chine to Gunnel is 38" Forward the freeboard will be more.

I am not sure what you mean by inside depth?

The dead rise is 2 to 3 degrees aft. There is some moderate increase, but not much until you get close to the windshield--where I would say it is 20 degrees, all of the way forward, it is a little more than 45 degrees--theses are eye ball estimates. If you want specific stations measurements I do have an inclinometer, and can give you precise (actually the I phone will also work well this way, with an app). Give me inches from the stern, I will be glad to give you a dead rise measurement in degrees. (which is the usual way to measure).
 
Thanks, Bob.

I think inside depth is what you measured as depth of cockpit.

Like you, I am used to specifying deadrise in degrees but this particular hull is specified in inches.

I can eyeball it for the other dimensions.

Since Warren sent me the PDF link to the boat he is considering, I have to disagree about the deadrise in inches. It is always measured in degrees; It is in this boat also. By definition:

Deadrise: is the amount of V-shape on the bottom of a boat’s hull, measured in angles at the transom of planing powerboats from the horizontal plane.

Well, if you know your distances from the center to the chine, and the inches of deadrise, converting to degrees is a simple matter of trigonometry. If you aren't mathy, post your numbers and I (or I'm sure someone else who might beat me to it) can help calculate so you can make an apples to apples comparison.
 
My post may not have been clear--the PDF gave the deadrise properly in degrees. Now as to what "amidship;s" really means--and forward really means in that specific boat. That is why deadrise is typically given at the stern--Deadrise elsewhere in the boat will be variable--wth the exception of a cross planked Garvey or other flat bottom boat.
