I was thinking of a really damn bright light (i.e. so even the crazy
weekend powerboaters from Miami will see it)...a battery sized to
match (12hoursX draw/H) & stored in a cockpit lazarette & coupled with
a small solar panel. That way I can have a bright anchor-light while
not drawing power from my house batteries.


Problem solved.....

Draws no power...runs 30 hours on a "charge"

Haul it up on a halyard....
