What Is a Catamaran?
Two hulls, a wide, stable boat - the new standard in comfort, but a maintenance world where everything comes in pairs.
A catamaran is a vessel made up of two parallel hulls joined by a bridgedeck. Compared with a monohull, she sails without heeling, offers far more living space for the same length, and can get into shallow coves thanks to her reduced draught.
The table below compares the two worlds.
Monohull - Catamaran
Feature | Monohull | Catamaran |
|---|---|---|
Passage | Heeled over | Living space |
Narrow | Very spacious | Systems |
Single set | Almost everything is duplicated | Haul-out |
Standard lift | Needs a wide sling spacing; not every lift can take her | The key reality for an owner is this: almost every system is duplicated — two engines, two fuel systems, two propellers, two rudders. Maintenance items and haul-out labour must be planned accordingly; you don't budget for a catamaran as if she were a single-engine boat. |
Simple rule for a catamaran maintenance plan: list every routine job twice and keep both sides in step; engine hours and anode changes should stay aligned. Book winter lay-up earlier than for monohulls; suitable space for a broad boat is always in short supply in the Aegean.
