I generally use coal boats where I can, but randomly hailing them isn't a great solution.
What I do is go to: http://www.lock13.co.uk/
Find the boat which is covering the area I want, then have a look at their facebook page where they'll generally post their movement over the next week or so. Then text them with my boat name, where I am, and what I'm wanting. I've often had coal dropped off for me while I'm away from the boat.
If they don't do social media, just text them to find out where they'll be.
