Replacing compression post w/SS post?
 
I'm in the process of completely restoring/upgrading an 82 C-27. My compression post looks pretty good but does show signs of having been wet (duh). This got me to thinking....should I replace the wooden compression post and upgrade with a stainless steel type? I'm a big fan of overbuilding and feel like a stainless steel upgrade would give me one less thing to think about down the road.

What are the advantages/disadvantages?

What would I step it on? Should I upgrade from what is currently under there. I already plan on doing the factory recommended keel upgrade so doing a bit more work while I'm in there is no big deal.

Thoughts?

I have one in my boat. I don't see how there would be a disadvantage except for cost.

I would make sure that the bottom support is well constructed. Rot and crush proof. I would think any local shop could weld up a pipe with top and bottow plates.

I have one from steel, will replace with stainless in 5 years. Works great besides having to scrape and paint every season on the foot. (bilge contact).

My previous boat (Cal 9.2) was built with a SS compression post. Liked that it needed no maintenance.

S.S. is a good idea. Make it beefy so it gives the look of strength. I'd go 3" OD max. It will look "right". Try to step it on a plate that bridges two hefty athwartships floors so the load is well spread out. Put a nice wide beefy flange on the top of it. Make the flange dimensions greater than the footprint of the mast.

Get it sandblasted and have it powder coated, it will outlast you...

Are you trying to sneak a stripper pole aboard on the sly? Dave G

Lol climbhike thats what I call my stainless steel compression pole. The stripper pole on my boat is 35 yrs old and looks great and sturdy.

Hmmmmm?

Imafoolforstainless in most places/uses; but a honkin' big, shiney post in the midst of almond FG and teak woodwork just goes against my grain. Mebbe ifnit. was bronze? ;)'

Powdercoat is great stuff, but I wouldn't use it on a compression post that extends into the bilge. The rust will get in between the powdercoat and metal and push the coating off. Repowdercoating is more expensive than repainting.

There is a stainless compression post in the middle of my boat (it runs through the main cabin table), which otherwise has a fairly woody interior. I think that it looks fine and it matches the polished stainless chainplates. You can image search for "pearson 28-2" to see lots of examples. The post is made at Bob Perry suggests, with a large plate at the top and bottom to spread the load.

I never confirmed this, but when I owned a Catalina 25 it looked like the compression post was hollow and made of 4 boards joined together. If the C-27 is the same way you might be able to run a metal post down the center of it to keep the wooden load with the structural integrity of metal.
