What does capsizing mean?
Capsizing describes the moment a boat or ship turns over in the water, leaving its keel or hull facing upward instead of upright. It appears most often as the present participle of the verb 'capsize' — as in 'the dinghy started capsizing in the squall' — but also serves as a noun when writers refer to 'the capsizing of the ferry.' The word carries strong connotations of danger and emergency: capsizing is one of the leading causes of small-vessel fatalities, since an overturned craft can trap occupants beneath the hull even if it remains afloat. For that reason, the term is common in maritime safety guidance, accident reports, insurance documents, and news coverage of sea disasters. Although primarily nautical, it can occasionally describe anything overturning abruptly, such as a car flipping on land. Related forms include the base verb 'capsize' and its past participle 'capsized.'
To turn over in the water so that a boat's keel faces upward; used in continuous constructions such as 'the boat was capsizing.'
"The crew scrambled for life jackets as the yacht was slowly capsizing."
Almost always used with boats or ships; extended figurative uses are rare and informal.
The act or instance of a vessel overturning in the water.
"An uneven load contributed to the capsizing of the passenger ferry."
Often preceded by 'the,' as in 'the capsizing of the ship'; typical of formal reports and journalism.
A vessel doesn't have to sink to be lost — most small boats that capsize actually float upside down, which is why sailors are taught to stay with the hull rather than swim away.

Etymology of capsizing
The verb 'capsize', from which 'capsizing' derives, entered English in the late 18th century as a nautical term. Its ultimate origin is uncertain, though it has been linked to Spanish nautical vocabulary relating to plunging or upsetting a vessel. It spread quickly through British and American maritime usage, and 'capsizing' emerged naturally as its participle and verbal-noun form, now firmly established in both British and American English.
