You're better off taking $30 a month and putting it into a savings account - then when/if your shit gets stolen or wrecked you'll have some money to replace it. With insurance, all you're doing is insuring you will loose money in the long run.
I've paid WAAYYY more $ into insurance (homeowners, veh, renters, etc) than I've ever gotten back. The only exception would be liability - but then again if you flip a boat and someone get's hurt or worse it's not going to cover it. I don't even know what it would cover? Maybe if it falls off your trailer and a car hits it??..? I'd be curious to know what liability would cover.
