Thank you! Hopefully you found the weight out of curiosity and not for a problem.

I pulled it out to change the pin and clean inside the trunk.

What caused you to change the pin? Also, do you have any photographs of the pin location, the entire board, etc. that you can send?

I'm in the process of doing a keel up refit. Gutted the boat to a bare hull and rebuilt everything. I knew the pin was original, 1973, so there was no question of the fact that it was due. It was a relatively simple process. I used a framing square slid  up between the board and trunk to define on the  outside  of the  hull where  the pin was fore  and aft. Then measured up to define how high. Then ground off the glass to expose the end  plates which were held on with slotted head machine screws. Removed the end plates and pushed the pin out with the board supported. To remove the board we just picked the boat up with a hydraulic trailer and set it back down. She is blocked low. 
Stripped off all the old paint on  the board, and barrier coated it. Also removed all of the old aluminum sheaves, one was in the board itself. There were large fiberglas washers between the board and the trunk which looked sloppy to me. In place  of  that I made  some G-10  bossing  on either side of the board in way of the pin hole, faired into a smooth transition to make up for the washers.
A related project was removing the old cable set up that  ran aft under the engine and came up into the port cockpit locker. That all went in the dumpster. Installed a fiberglass pipe running from the top of the trunk up through the overhead in the cabin. Two turning blocks on the cabin roof, to a rope  clutch  and Anderson 10 winch on the coachroof to starboard of the companionway. Used polyester covered dyneema for a replacement cable.
