deadrise measurements and hull dimensions

[The red boat]

I have 1955 Crestliner Buccaneer (with ’55 RD-17 Johnson) and I’m trying to get a new trailer for it. The original one was a handmade contraption that has seen better days.
I’m doing all the measurements but having a hard time determining the deadrise dimensions of the hull.
Has anyone ever taken such dimensions or have a resource that gives detailed drawings of the various Crestliner models?

thank you.
yes I had that but it doesn’t give any detailed dimensions or angles of things.
I do appreciate your response tho!

These angles and measurements are helpful to some degree I’m sure if you are ordering from a catalogue or ordering one from a dealer with the salesman driving you insane. I don’t understand the numbers on paper as some may. I am hands on in understanding the problem. Furthermore anything ordered based on these arbitrary measures will need to be adjusted to the specific hull. Listed below is how I successfully set up a trailer for my personal boat.

Most trailers offer a world of adjustment options. Find one long enough for your boat. Set up the keel on the rollers adjust so the front of keel sits about 3/4 of an inch to an inch lower than keel about 3 inches from rear of keel at transom where last roller on trailer should be. Adjust post so bow stop engages just above the bow eyelet and winch cable or strap is pulling strait forward just below bow stop. At that point the boat has 100% of the load supported by the keel adjust bunks to divide the load and stabilize the craft, the keel rollers should have 70% of the load and the bunks should support the remaining 30% of the load. With the hull being level from side to side and with trailer set level front to back the boat should be slightly bow downhill into bow stop that is why keel should be 3/4 to 1 inch higher in rear than the front. Also with bow stop just above bow eyelet in a panic stop that will mitigate the risk of the bow wanting to ride over the front of the trailer.

I have a commander crestliner 1955 the 12 foot little cousin of your boat set up a new trailer for it this season my bunks are set just inside the lift strakes and I have the keel and winch post set up as outlined above. It launches very well with bunks just submerged, recovery is a breeze I just back in so the rear third of my bunks are below water. Hook up the winch with the keel centered on the rollers and the boat walks right up the trailer strait and true in most cases as the lift strakes ride the bunk edges it really doesn’t have a chance to get too far out of line
