For weeks now I have watched party and restaurant boats leaving the Docklands on Friday and Saturday nights. Last night while eating dinner I noticed one loading up with passengers and I noted the time so I could plan a recording session. Tonight I came out at 7pm in time to catch on of the boats loading up and preparing to go. This allowed me to capture a good amount of material over the 20 minutes it took to get ready. Using the hydrophone I got tons of material of its engine running underwater, as well as some material with the H4Ns built in mics to capture the surface sounds.
When the boat finally manoeuvred out of the docks I got a good sample of its engines as it reversed and moved out. Just as the main boat was pulling away a second boat headed in. This gave me a great opportunity to capture two boats and to be able to compare the differences in sounds. I could really understand how navel personnel could tell what type of boat they were near by the sound of the screws (propellers) the incoming boat was much older and I could hear that its motors were not running as smoothing as the first boat. I now want to sample some more boats so I can get a selection of different boat sounds.
