Re: Boat insurance going up 17-18% a year normal?
As Home Cookin' said, you really should look at the $100k liability. If you cause an accident or someone gets hurt on your boat, lawyers will sue for well over that amount and you'll be paying that out of pocket. Part of what you need to consider is your boating style. If you are pulling tubes and skiers, going fast in crowded lakes, taking guests out often, boating in rough conditions, you should strongly consider high amounts. If you're Walter Matthau in Grumpy Old Men, putting along with a 5hp in remote bays looking for walleye....your risk is much, much lower.
So you need to consider your boating habits, conditions, and even the types of people and boats that you encounter. Hitting someone on a small lake in the midwest want be as big of a lawsuit concern as hitting someone's cabin cruiser near Manhattan.
Things to think about.
