Look at opencv , it has most of the functions you need , its free and os available on linux , mac and windows. Use it with c , c++ or python.
Could even do object tracking fairly easily.
Make sure you boat has a nice bright colour that stands out wll. Once you have the detection working , then you can change the colour to one with a lot less contrast to see how well your solution works.
