Use a Harken Carbo Air Block and it will pretty much never need lubrication
and it won't rust... Or conduct electricity... Or conduct EMF.

A 40mm may be big enough but the 57mm is a guarantee.  Use the cheek
mounted style.  I've provided a link below.  ~$45.

Stus-List Hanging a dipole

[Andrew Frame via CnC-List]

This isn't for my boat, but it is about marine hardware, sort of...

First, background:

I have to hang a dipole antenna for our emergency management amateur 
radio station. We're going to take advantage of some well placed 
concrete light poles in the parking lot. The dipole must be able to be 
lowered to the ground during severe weather, so a pulley will be mounted 
to the top of each of three poles.


Normally, for an easily accessible location, I'd get hardware-store 
galvanized pulleys, lag bolt them to the top of the pole, and grease 
them once or twice a year.


But, accessibility *is* going to be an issue. I have to get the fire 
department's bucket to get to the top of the pole.


So, I pondered using marine stainless hardware and pulleys for the 
installation. I'm not sure, so posting this for those who wish to offer 
a thought. Feel free to respond direct if you don't want to post to the 
group.


Thanks in advance,

A!
