I tried an owl too and it worked for about an hour. I found this low-cost, low-tech solution somewhere on the internet a couple of years ago and it works. Just string some kind of line (I used orange yarn) along the dock posts on one side of the dock about a foot high and criss-cross it over the boat. Apparently the birds don't like anything interfering with their path when landing and taking off. Be careful that the line doesn't become a tripping hazard and ensure that the line doesn't dangle in the water. I do get an occasional duck but they are friendly enough and don't make a big mess.
