I met a young couple at the Mosquito Creek dry dock in North Vancouver; they had recently purchased an old Catalina 27 like mine so of course, swapping stories was more fun than working on the boat on "the hard." For lighting they told me they used the lights you can purchase for patio that have solar panels incorporated into them. They leave them out during the day and take them inside in the evening.Has anyone else done this? How long does the light last; I forgot to ask them?
