Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод "палубный луч" будет ошибкой. Здесь "beam" означает балку, брус, перекладину, а не луч света.
- Не путать с "deck board" (палубная доска настила) – "beam" это несущая конструкция под досками.
Common Mistakes
- Using 'deck beam' to refer to a railing or handrail (which is a 'guardrail').
- Confusing it with 'keel' (the central backbone along the bottom of the hull).
- Using it as a verb.
