freeboard

n.

干舷；净空；超高；

1. Machinery casings may, however, be exposed if there are no openings giving direct access from the freeboard deck to the machinery space.
   然而，如果没有提供从干舷甲板到机舱的直接通道，那么机舱围壁应该是露天的。
2. The low freeboard and the shallow draught made the vessel vulnerable to swamping, and it would roll heavily on anything more than moderate waves.
   低干舷和浅吃水度让船只在湿沼地带很脆弱，它会在任何比一般海浪猛烈的海水条件下剧烈翻滚。
