I mentioned in yesterday's post being surprised how much water drained out of each stabilizer fin. A couple of people emailed asking me what was up, so I emailed the west coast service rep for ABT Trac. He replied a few minutes later:
"Yes you are correct a lot of water will come out of the fins as they are hollow and designed to fill with water. They are this way so they will become neutrally buoyant when under the vessel. There is a small foam piece in the very front of the fin (forward of the socket ) than will keep the fin from going to the bottom but otherwise the rest of the fin is like an airplane wing that is hollow in design. And if it were sealed it would want to float." So now we know!
