- Unit values and concentration
- Boats carry high unit values, and contract values follow. Higher values can mean fewer but larger contracts, so a small number of claims can move results more than in a book of many smaller contracts. Ask whether your units and values fall within eligibility guidelines, and how concentration is reported.
- Seasonality and storage
- Boats are used seasonally and are often stored for months. If deliveries cluster in certain months, written premium will be uneven through the year. Because premium earns over time and claims develop later, judge results across several underwriting years rather than one season.
- Claims
- Marine engines fail differently than car engines, from sustained high RPM to saltwater intrusion and heat cycling, and repairs often need specialized technicians. Ask how claims are adjudicated, how labor rates are set, and whether saltwater and freshwater use are treated differently under the contracts you sell.
- Contract terms and reserves
- Marine service contracts are often the longest running product a boat dealer sells, and owners often keep boats for long ownership cycles. Reserves are held for as long as the contracts they support remain in force, so long terms keep part of each reserve committed for years. Ask how premium earns over the term and when funds may become available.
- Storm exposure
- In coastal markets, some products may include named storm variants where eligible. Weather can bring many claims at once in one region, so ask whether any storm coverage is part of the ceded product mix and how that exposure is priced and reserved.
- Mixed lines and groups
- Personal watercraft are sold by marine and powersports stores alike, and a boat sale can also include a trailer and electronics, each with its own product. If your store sits in a group with RV, powersports, or automotive stores, ask whether each line can be reported separately so a blended book does not hide how each part is performing.
