## Definition

a boat with two side-by-side hulls joined by a deck, which makes it fast and steady. You see them used for sailing trips and island tours.

For teachers: a sailing or powered vessel with two parallel hulls connected by a deck or frame, valued for speed and stability.

## Examples

- We sail on a small catamaran every summer.
- The tour group boards a catamaran in the morning for a day trip to the nearby islands.
- The catamaran glided across the lagoon on twin hulls, barely rocking in the swell while single-hulled boats pitched beside it.
