I wanted to caveat my previous post. Progressive is good for a lot of people and is not a bad insurance company. They just don't compete in MY scenario, not even close. The good thing is that almost anyone can get insurance which is important for different things so I commend them, Geico, "The General", etc. at providing creative insurance programs for different people through all stages of life. I won't discount those things, they are important.
But what I have found is that by covering multiple things, where I live in Michigan, with my credit, income, area I live in, home, boat, auto's, life, towing and the specific coverages and riders I have on personal property, computers, Jewlery, tools and deductible, etc..... They cannot even come close to what I am paying. Also my Agent is about 3 miles away so if there is a big problem, which there hasn't been, I can drive over there and we can get it squared away.
I wanted to provide some clarity to my initial post and hopefully not discourage anyone from looking at all possible avenues for their own personal scenario. I will say be very diligent on understanding on exactly what you are paying for and the context and parameters of the policy and what it will and what it won't cover. I have seen it before where someone has a good price on insurance and is basically hung out to dry if something happens. On 40k -90k boats, it is a lesson you don't want to learn the hard way. Read everything on the policy especially the exclusions.
The neighbor with the Monterey had his boat stored in a yard and a heavy tree branch fell on it. His insurance company covered him for theft, damage while in his possession or operating or while stored at his house, slip, or in a marina dry storage/rack. Didn't cover it basically be parked in a parking lot. The damages wasn't much, about $1,500 he said but he changed insurance companies and made sure the exclusions were very clear.
Also another good thing. If you store your boat during an off season, verify with your insurance company your covered for Theft, Damage both intentional and non-intentional, Rodent/Animal Damage, Environmental Damage, etc., etc. Also some may make a distinction between a Professional Service/Company (that does this as a business), and some dudes barn who rents you some space. You may be surprised if you don't read through it all. I am just went through this with my insurance company and was asking more questions than the Riddler and having him send over the documentation that clarifies each point, since I am considering storage soon. That makes me sleep better. I have enough surprises with family, kids and work. Don't need them with my insurance company when shit hits the fan.
