After pulling out the rotting bulkhead to repair it, and pulling out the compression post which I replaced 3 years ago, I am thinking that I don't know exact;y where to place the compression post! If you look at the picture (it is taken looking forward at the bulkhead with the compression post removed), you see a raised area (about 1/16") on the gelcoat of the beam that the comp post rests on. Now, looking at the boat logically, this to me looks to be dead center of the boat, and the the compression post should have this line right in the middle of it's base. This means that of course a good fit would be to etch off a bit on the port half of the post. Since nobody pulls this post when it is healthy, you would probably NEVER notice. But the question is, does anyone know if the post butts against the raised line or if the line disects the base of the post? If not, does anyone have a picture of this area with everything fully installed? You see, if you pull only the post, then the bulkhead screw holes help your re-alignment. If you pull both (like I did), then replacing it and the bulkhead is an issue! Thanks, Marty

Many don't replace it with the original materials

Many of the posts were not replaced with the original material. Ours was replaced with a stainless steel post, other with aluminum beams. Once the support is in place you can just build a box around the entire support to match what was there. This method eliminates ever having to replace the compress post again.

Stability, not looks

The question is more about where to place it in order to make sure it is in the place for most support. In other words, where is the center of the post supposed to rest? Marty

Hunter 31 Compression post

You may want to check the integrity of stringers above and below the post before final fitting. On our 1984 31 there was a block of wood in the top stringer that had gotten wet and rotted. We had to pull the post back out, glass in a new block and put it all back together again.

Patrick's pics may illustrate it...

From Patricks pics, it looks as if the port side of the post butts up against the raised area.
