We're launching this weekend and we'll be storing our boat in a slip all season. While I've kept it in unattended for a week before, this is our first time keeping it in the water all year. I'm fairly anxious about it since I'll be 4+ hours away and may wind up being away for up to 3 weeks.

I have a couple basic, stupid questions. While we're away what can we leave on safely? I'm thinking battery charger of course, and I'm assuming people leave their refrigerator on. What about heat? It's still very cold (near freezing) at night. Anything I should make certain is off?

Also what should my expectations be from the marina in terms of keeping an eye on things? Lots of storms in the spring, maybe even a bit of snow - how far amiss should things have to get before I should expect a call from them? They say they pump out dinghys for you after a storm (but I don't have one yet) so they're clearly walking around. I'll definitely have the conversation with them too of course.

Lastly, any other general advice I should hear? I'd like to avoid making rookie mistakes if I can.

Thanks for the patience assistance!

Put your phone number in a window where it can be seen from the dock. That way your neighbors can call if they see something wrong.

Make friends with all the live aboards near your slip. Meet all your dock neighbors and let one or two know where you keep the key.
