with solar powered, battery trickle chargers. I've seen one for £20 and wonder if it's all smoke and mirrors (a waste of time) or are they worth having ?

If your boat has extended periods without use, then I would say it is a good idea. Your battery will lose its charge over time, and having a trickle charge will help to keep it in good condition.
I dont know about one for £20 though. I paid £60 for a 5 watt 12v solar cell which gives about 0.4A. Check the specs, you may have a bargain.

Obviously it depends on the amount of light falling on it, but no I have not measured it. What I can tell you though, is that when working on my van (where the unit is fitted) and had the battery disconnected, the dangling battery terminal when brushing against the bodywork caused visible sparks. Not big ones, but visible.
I presume in the spec somewhere I am sure there is a line that states how much lux or lumens is needed to produce 5 watts.
