We got an early start on monday to get ready to head up the Miami river to a shipyard where we could have our antenna switched out. We loaded the new antenna onto the ship with one of our cranes. Once we had everything loaded we made our way to the river. We had to cross under 6 different draw bridges along our way. Once we made it to the ship yard I helped prep the new antenna and decommission the old one. We then had a crane come and swap the two antennas. I helped secure the new antenna to its platform. We then headed back down the river and to port. The rest of the week we worked more on general maintenance of the ship. We filled our water tanks. We also topped off our diesel tanks with 2,000 gallons of fuel.
