I never had boat insurance before, because the boat was allways paid off and trailered. This year I bought a 21ft and will be putting it in a slip.I don't have a boat loan on it, but I think that I should carry insurance on it because it won't be in my sight everyday. The blue book value is about 18,000 I only paid 10,000. My question is what amount should I insure it at?, and what insurance seems to be the best?. I did get a quote for boatUS, but haven't tried other carriers yet, though I would check out what you guys think. Thanks in advance.
