What's the Best way not to put a hook in your hull when rebuilding it

[73Chrysler105]

I have had a lot of differing opinions on this and wanted to see if we could get a consensus on the subject.

I have my hull on a stand but not sure if I am going to put a hook in it on the stand and if I already have whats the best way to determine if I will have a hook in the hull.

I have attempted to square the hull out on the stand its on by picking a point from each corner and drilling a hole in the rub rail area. I ran a line crisscrossed and made sure that from each hole to hole was the same distance which should mean its square but since I am dealing with a hull with the cap removed it also could mean one side is still push in more than the other. Should I do it from the point on the bow to the rear corners of the boat as well?

Should I have a bunk board styled stand like a trailer will that keep it from getting a hook or would it be better to more support the sides and keel?

Just looking for a consensus of opinions here that might help me and others.

Building a cradle that fits your hull snugly before removing any structural members like decking, stringers, and transom is the best way.

Well that's a little too late besides mine were pretty much gone already. Guess I will just measure it out and hope for the best. I figure if I can keep it square and level from side to side and front to back it should be pretty straight down the keel.

Run a string from bow to stern right down the middle. measure from the string to the sides every foot. you can also hang a small weight every foot to simulate a plum bob to check the keel is straight along the string. I'm guessing here...

Not a half bad idea

Use a carpenters level

on the edge of the hull at the stern of the boat and across the transom and level the boat. Run a line from a hole at the stern of the boat at the rub rail level and to the bow of the boat at the rub rail level and hang a line level on it.

A full length bunk cradle is the best way to ensure the boat is properly supported.

Thanks WOG that's kinda what I am already doing.

Here is my whole process of what I did.
1) Build a stand for the bow and the stern supports
2) leveled the transom and bow independentantly
3) Squared the hull from 6" from the stern to 12" from the bow at the rub rail using a criss cross measurement
4) Install 2x6 bunk boards to support as much of the hull as possible ran 2 on each side of the keel.
5) recheck the level and squareness of the hull.
6) installed strings crisscrossed at the squaring points to be able to watch for fluctuations in the hull

I used a long level and string levels like you suggested. I want to make sure I am on the right track. Talking about this though I never made sure the front and rear stands were squared up to each other before everything else was done at this point would it make any difference?

Not really As long as you have measurements of the cap dimensions and you keep everything level and within the given dimensions you'll be fine.
