Start with the vessel and the work it performs

Commercial marine risks are shaped by more than a boat’s value. Passenger capacity, cargo, operating waters, season, crew, contracts, docking arrangements and the work performed all affect the insurance review. A tour operator, marina contractor and workboat owner may use similar vessels but face very different losses.

Westoak helps Ontario operators organize those facts before approaching an insurer. Pleasure-craft insurance is generally not designed for a vessel used to earn revenue or fulfill commercial contracts.

Coverage to consider

Depending on the operation, a marine program may include:

  • Hull and machinery coverage for insured physical damage to a vessel and installed equipment
  • Protection and indemnity or marine liability for covered injury and property-damage claims
  • Cargo, tools, portable equipment, tenders and trailers where applicable
  • Pollution, wreck removal, salvage and towing provisions, subject to policy terms
  • Property and business interruption insurance for shore-side operations

Coverage territory, navigation limits, deductibles, valuation method and lay-up periods deserve particular attention. A policy written on an agreed-value basis can respond differently from one using actual cash value or another settlement method.

Documents and operating controls matter

Transport Canada states that eligible small commercial vessels can enrol in its Small Vessel Compliance Program to help owners meet legal obligations. Enrolment is not a substitute for compliance, and insurance does not replace required licensing, inspection, maintenance or crew qualifications.

Underwriters may ask for surveys, maintenance logs, operator experience, incident history and evidence of safety procedures. Passenger operations, diving, towing, chartering and carriage of hazardous goods should be identified explicitly.

Review contracts before accepting the work

Marina leases and customer contracts can allocate responsibility for vessels, docks, cargo and environmental damage. Indemnity clauses, waivers of subrogation and insurance-certificate requirements may not align automatically with a standard policy. Share agreements before signing so your broker can identify gaps or requirements that need insurer approval.

Prepare for a useful insurance review

Bring a current vessel schedule, registration details, values, operating territory, seasonal dates, crew information, revenue, contracts and five-year loss history. Also describe planned changes to routes, activities or passenger counts. Contact Westoak to review commercial marine insurance without confusing it with coverage for personal boating.
