What type of technical drawing

I have a Columbia 8.3, that I am trailering from California to Texas.

I just bought a trailer and need to add in the supports. I have found general dimensions for the boat, but not precise dimensions.

Searching through the internet, I have found a site that has all the technical drawings for the boat. What type of techinical drawing would I need to order, so I can get all the correct dimensions of the hull?

I was about to order the General Arrangement drawing, but wasn’t sure that it would have all the necessary details.

Re: What type of technical drawing

You would need the lines drawing, and know how to read them to get the shape right, and the accommodations plan to see where framing and the prop shaft are located.

But in reality, even with the lines drawing, it would be difficult to accurately construct "bunks" that would fit the boat since the molds for a value oriented production boat rarely match the lines drawings. But also, you will want to be able shift the boat on the trailer to make sure that you get the tongue weight right.

If you really want to build a custom fit trailer, it would be a better idea to accurately measure the boat on the trailer and then careful build the supports.

A better plan B would be to weld up a support structure for the bottom of the keel and three sets of properly braced tubes that will accept the adjuster screw and pads from jackstands.
