Are you on board or are you onboard?
Are you on board or are you onboard? Onboard is one word (sometimes hyphenated—on-board) when it comes before the noun it modifies (e.g., onboard radio, onboard computer). Elsewhere, writers usually make on board two words. For instance, one might write, “We brought a radio on board so we could have an onboard radio.”
Can I stay on board on a cruise?
Can I stay onboard the ship while in port? Absolutely! Whatever the reason, you're in no way obligated to disembark a cruise ship while visiting a port of call. Mosts guests choose to get off in most cases, but they may do so at different times, for different amounts of time, and some won't get off at all.
