Speaking of lanterns aloft...There are any number of mock-Coleman-lanterns in the stores these days, some even branded by Coleman, that use LED arrays and run for up to 48 hours on the self-contained batteries. Some with little remote control keyfobs, too.
Should be easy enough to just hoist one of those aloft, they should be economical and utilitarian things to have on a boat. Often under $20 at the bigbox stores. Some using C or D cells, others lantern (6v) batteries, etc.
