I'm thinking a solar panel,too

Thank you for answering my questions about solar panels.

Right now I have the old original stereo in my boat, and just the one battery. I know I should get a 2nd battery, and its on the top of the list of things to do. But I was wondering if anyone might now how long I could safely run this old radio till i would need to start up and cruise to charge the battery? I have no idea how much power it draws, prob not much being so old. Also when I do get another battery I'm surely going to upgrade the stereo also. I wanted to see if anyone could tell me how long they can run an upgraded stereo on the 2nd battery? Just to put a number on it, maybe a 200W stereo with 2 speakers only? Last question, is would it be worth while (and would it it get the job done) to get one of those small/cheap (harbor freight) solar panels to keep up charge on the 2nd battery? I expect with the kids a day would be to go out and blast around with the tube for a bit, then anchor somewhere for the rest of the day and swim. Thanks!
