I’ve been using Dolphin Insurance in Vancouver for the past few years. Never had any claims (knock on wood) but they are great people to deal with. The underwriter for my policy is Lyod. Reputable international underwriter in the marine business. Your insurance cost will depend on your coverage and limit but you are looking at $600-800/year for an average coverage. Add more coverage/ limits and it could really go up. If you are a Power Squadron member there’s always discounts to be had. Call 2-3 brokers and get some quotes. Research the reputation of the broker and underwriter before going with the lowest quote.
