'Uniform' is the correct and probably best understood signal.
Toronto harbour has a small fleet of booze cruisers-for-hire that ply the waters from noon until midnight between mid-May until October on the business plan that nothing says "thank you, employees!" like seasickness, shrimp and an open bar.
We of the sailboat ilk tend to call them "disco boats" due to the ear-splitting sound systems they employ and the sort of flashing lights that would induce epilepsy on land.
In the matter of signalling, I suspect only a flare aimed directly at the wheelhouse would have a chance of being noticed.
