General Liability Buying Guide for Marine Construction Contractors

When shopping general liability for your marine construction contractors business, evaluate each quote against these criteria:

Coverage form: ISO CG 00 01 (occurrence) is the standard. Non-standard or manuscript forms may contain restrictions. Ask for the policy form number before binding.

Defense provision: Does defense erode the policy limit, or is it paid in addition to limits? “Defense outside limits” provides significantly more protection for marine construction contractors.

Exclusion review: Read every exclusion. For marine construction contractors, pay particular attention to pollution, professional services, and are/custody/control exclusions.

Carrier specialization: A carrier that writes hundreds of marine construction contractors accounts understands your risk better than one quoting your class for the first time. Ask how many similar accounts the carrier currently writes.
