Removing the masthead was simple, just unbolt the two bolts that the shrouds are bolted to:

Here you can see the profile of the Marco Polo mast. I was pleased to see the styrofoam in there for buoyancy:

I removed a a couple of pulleys prior to this photo, but this is essentially the part. I now need to find some replacement pulleys for the ones that are stuck.

Otherwise, today I added some more hardware, as well as got the templates made for the new portals.
