Structure
Accessible hulls, internal structure, bulkheads, bonding, bridge-deck areas, deck mouldings, appendages and evidence of grounding, collision, stress, moisture or previous repair.
Multihull context
More than two ordinary hull inspections.
Cruising catamarans combine two hulls, a cross-structure, bridge-deck, large deck mouldings, complex steering and often duplicated propulsion and electrical systems. Their survey requires attention to how these elements interact.
Model-specific concerns are treated as inspection priorities, not automatic defects. The individual vessel is assessed from observed evidence, accessible structure, documentation and the condition found on the day.
Survey approach
Structure, systems and cruising reality.
Propulsion and steering
Twin machinery installations, engine spaces, saildrives or shafts, fuel systems, cooling, exhaust, steering linkages, rudders and the consistency of duplicated installations.
Cruising systems
Battery banks, charging, solar, inverters, navigation electronics, plumbing, sanitation, watermaker, refrigeration, heating and other equipment relevant to the agreed scope.
Lagoon experience
Practical familiarity with Lagoon cruising catamarans.
Experience with Lagoon 380, 410 and 440 models provides useful context for construction arrangements, equipment access, common refit patterns and the practical demands placed on liveaboard cruising systems.
Familiarity helps focus the inspection, but it never substitutes for evidence. Every boat is assessed individually, and a known model concern is reported only when relevant observations support it.
Buyer-side reporting
Priorities you can use.
The report distinguishes material structural or safety findings from maintenance, monitoring, documentary uncertainty and normal age-related condition. Photographs support the observations, and the findings can be discussed before you decide how to proceed.
“A known model concern is a reason to inspect carefully. It is not, by itself, a defect in the individual vessel.”
Planning the inspection
Access matters.
A meaningful catamaran survey benefits from access to both engine spaces, bilges, lockers, structural interfaces and electrical installations. A haul-out is normally recommended so both underwater hulls, keels, rudders, through-hulls and propulsion components can be inspected.
Provide the listing, model, year, current location and any known repair history when enquiring. The proposed scope, access, haul-out, possible sea trial, travel and fee are agreed before instruction.
