It doesn't have to be that compact in the boat context. I could even build or obtain a single largish one and distribute stable 4.5 or whatever volts around the boat. If you look at - say - http://www.amazon.co.uk/Stick-Click-Led-Push-Lights/dp/B0013LJUBU/ref=pd_bxgy_kh_text_b you could put them in lots of places, to give a well spread light without too many bright spots, and at just over a quid each could afford some investment on the power supply. The current isn't such that you'd need a hefty investment in wiring either. They do work out at about 30p each!
