The age old "rule of thumb" for cruising costs was US$12K/yr for small boat/backpacker young healthy people and old folks who like deprivation living.
- - US$25K for moderate size
monohull boats with a healthy middle aged couple with grown
children out on their own.
- - US$50K for upscale living in a comfortable fully equipped mono or
catamaran.
- - Beyond that there are significant variations based on age, destinations, and what you want to get out of the experience as mentioned by Roaring Girl. Subsistence living on land or sea can be
cheap but maintaining your equivalent lifestyle to land living on the
water is going to cost
money.
- - A huge factor in the costs is the
boat. New has upfront costs but minimal upkeep costs. Old has low initial costs and large (sometimes enormous) upkeep costs. If you must
purchase all your
repairs and
parts retail you are looking at some expensive cruising. If you can do
maintenance yourself and removals and installations of replacement
equipment you can save enormous amounts of
money. Your taking 5 hours to fix something is a lot cheaper than paying a
boat mechanic $500 or more for doing the same job.
- - So that is why the cost of cruising has such a wide variation in figures. Nobody is really "average" and no two
boats are the same.
