Most insurance companies that cover watercrafts offer discounts to people who have taken boat safety courses.
However, each insurance company will only offer the discount for specific courses. Find out which course your insurance company will honor, and make sure you take and pass the course! This will save you quite a bit on your premiums and you need the safety course anyway! Find out what other discounts you may be eligible for as well. Most insurance companies won’t tell you about the discounts unless you specifically ask about them.
