Steel yacht construction and underwriting
The distinct question is measurable condition. Unlike fibreglass, steel gives a surveyor a number: plate thickness. That measurement, rather than the boat's age, is what an underwriter actually assesses.
Hull thickness and corrosion evidence
- Ultrasonic plate thickness readings from a recent survey
- Corrosion history, particularly in bilges, under tanks and around fittings
- Coating system, its age and condition inside and out
- Anode and cathodic protection regime, and shore-power galvanic isolation
- Whether the boat has been kept in salt or fresh water
- Interior insulation and whether it traps moisture against the hull
Steel yacht policy conditions
- Whether corrosion and gradual deterioration are excluded — they generally are
- Survey frequency requirements and how recent readings must be
- Conditions requiring remedial work within a set period
- Settlement basis, since steel yacht values vary widely with condition
- Whether interior stripping for inspection is required and who pays
Documents for a Steel yacht insurance quote
Give every insurer the same vessel facts: year, model, length, hull material, rig, engine hours, standing-rigging age, survey date, storage arrangement and intended cruising area. Differences between quotes are only meaningful when the inputs are identical.
Frequently asked questions
Are steel yachts harder to insure?
Not if the survey is good. A steel hull with documented thickness readings and a sound coating system is a well-understood risk. A steel hull with no recent survey is a very difficult one.
Does insurance cover rust?
No. Corrosion is gradual deterioration, which marine policies generally exclude. Insurance covers sudden accidental damage; maintenance covers rust.
Prepare your quote properly
Insurers price what they can verify. Work through the vessel-details checklist before you request quotes, so every quote you get is built on the same facts.
