In total he spends almost all 52 weeks of the year at sea, at a cost of about $70,000 per year.
''I live life in reverse,'' he said with a chuckle. ''I have one week that I call my week off, or my vacation week if you want to call it that,'' he said.
Though Mr. Salcedo's lifestyle is unusual, it is not unique. Beatrice Muller, a native of New Jersey, lived aboard cruise ships from 2000 to 2009, including the Cunard Lines' Queen Elizabeth 2, before she died in 2013 at age 94.
Lee Wachtstetter, a Floridian honoring her husband's dying wish that she continue cruising after he died in 1997, has lived ever since aboard Crystal Cruises' Crystal Serenity luxury cruise ship. The 88-year-old, known to passengers and crew as Mama Lee, lives in a private stateroom for which she pays an annual fee of $164,000. This includes all meals, gratuities, cleaning, nightly ballroom dancing and Broadway-style shows.
What these and other like-minded, somewhat adventurous older people have discovered is that for little more than the cost of retiring to an assisted-living facility, they can enjoy many of the same amenities -- comfortable quarters; meals, social events and educational programs; and round-the-clock access to medical care -- while exploring the exotic waters of the Caribbean, Asia, Central America and beyond.

Statistical analysis has backed up their strategies.
A 2004 study in the Journal of the American Geriatrics Society concluded that 20 years in a retirement home for someone entering at age 65 would cost an average of $228,075, as opposed to $230,497 for the same amount of time aboard a cruise ship.
Naturally, the costs of assisted-living facilities and cruising have risen since 2004, yet cruising may still be affordable for some. Depending on the location, annual fees for assisted living can range from $36,000 to $72,000, according to 2013 data compiled at LongTermCare.gov. For about a hundred dollars a day more than the top end of that range, seniors can spend their retirement years in pampered comfort while visiting ports of call across the globe.
''You can go on a world cruise for under $300 a day, per person, double-occupancy,'' said Mara Hargarther, a travel agent and cruise vacation specialist at Dream Vacations in Ponte Vedra, Fla. That fare, she said, isn't a huge premium over the costs of some high-end assisted living facilities.
And, much like frequent-flier programs, most cruise ship companies feature loyalty programs.
''The upper tiers of these loyalty programs would afford passengers special rates, special upgrades and the opportunity to access concierge-type services on board,'' said Jeff Smith, a senior vice president at World Travel Holdings, a cruise agency based in Virginia Beach, Va.
This creative approach to retirement comes at a time when the popularity of cruising among older people is on the rise. Cruise Lines International Association, an industry group, reports that 25.3 million passengers are projected in 2017, up from nearly 18 million in 2009. Historically, nearly half of those passengers have been between the ages of 50 and 74.
