What is the average cost for boat insurance in Miami?

Depending on the amount covered and the size of the unit and its location, I think it would be between $500 and $1000 per year. What you can expect to be charged are property taxes, which are about a yearly 1. 75% of the market value of a property and is adjusted accordingly every year.

Firstly the cost depends of the length boat, and of the boat value, for example in this URL you can calculate the insurance (https://www.boatus-insurance.com/insappNew/?AID=006&AButton=01&ASource=&ID=49EA11BDA317DA3713B21D10B3A2D41C&AHits=4194) and in this other you can find information, http://www.miamidadeinsurance.net/Florida-fl-miami-insurance/Florida_Boat_I.html, there is a range of $15,000 and can be increased to $300,000
