The excursion took place during a voyage on a P&O cruise ship, as part of their itinerary which includes various destinations throughout the Caribbean. While in the water at Shitten Bay, Jeffrey was noticed by staff floating face down and unresponsive. Efforts were immediately made to rescue him, and a rescue boat was dispatched to bring him onboard, where CPR was administered. Despite attempts to revive him, he did not regain consciousness and was pronounced dead around 1 p.m. that day.

A spokesperson for P&O Cruises expressed condolences, saying, “We were deeply saddened by the death of one of our guests. Our thoughts are with his family and loved ones.” Family members described Jeffrey, who had been quite active even into his retirement, as “strong and sporty.” His wife, Jean, illustrated his character, noting that he was indeed “fit for his age,” and there were no known health concerns prior to this incident.
However, a post-mortem examination revealed that Jeffrey had underlying health issues that may have contributed to the tragic outcome. Chronic obstructive pulmonary disease (COPD) and severe coronary artery disease were identified as potential factors affecting his health and physical capacity. The official cause of death was determined to be asphyxia due to drowning, with submersion in seawater cited as a secondary factor.
Henry Charles, the assistant coroner for Hampshire, hinted at the possibility of cardiac arrhythmia induced by physical exertion leading to Jeffrey’s loss of consciousness before he drowned. “It’s highly likely that the physical stress caused by swimming precipitated a cardiac event,” he remarked, acknowledging the complexity of the situation and the uncertainty of other contributing factors.
Jean Jeffrey expressed her bewilderment at the circumstances surrounding her husband’s death. She emphasised his experience with the sea, cultivated through both recreational sailing and military training in sea survival. “I find it very hard to believe that he was shocked by entering sea water. He had a read of the sea. It was unforeseen and unforeseeable,” she stated, highlighting her husband’s comfort and familiarity with the aquatic environment.
The Iona cruise ship, operated by P&O, accommodates nearly 7,000 passengers and crew, showcasing a variety of Caribbean itineraries originating from Bridgetown, Barbados. Travellers aboard the cruise often visit popular locations such as the British Virgin Islands, Saint Maarten, Martinique, Antigua and Barbuda, Grenada, and St. Lucia, in addition to Saint Kitts and Nevis.
John Jeffrey’s passing has resonated with many who knew him, generating an outpouring of grief from friends and family. His two sons and beloved wife will remember him not just as a capable aviator and retired military officer, but as a devoted family man who embraced life with a youthful spirit.
This tragic incident, serving as a stark reminder of the potential risks associated with water activities, underscores the importance of awareness, especially for older adults engaged in physically demanding leisure pursuits. As investigations continue and further details surface, Jeffrey’s legacy will likely inspire discussions about health, safety, and the adventures that await individuals in their retirement.
