There are major USA insurance companies that handle multiple lines of coverage including home owners; liabillity; motor
vehicle; and recreational vehicles (which includes boats). If you have your home owners coverage with such a company you can normally get a very good rate on boat insurance. Normally the boat insurance coverage is only for USA coastal waters and the Bahamas
. Also the coverage is usually only up to $100K on hull coverage. These insurance companies sometimes act as brokers for boat insurance from other sources for more expensive boats.
- - If you want/need coverage outside these limits then you deal with international maritime insurance companies that sell their insurance through brokers/agents such as I.M.I.S. or Blue Water
or dozens of other brokers/agents.
