found another actual costs from cruisers who keep track of them
Thanks Don. Interesting. An overall monthly average of $2,767, with a low of $957 and a high of $8,893. Looks like they a healthy middle-aged couple who cruised the Caribbean for about seven years on an older, fairly traditional, 44 foot boat. Good to know.
Of course, this is just one data point. To make this truly useful (statistically significant) you need to know how many similar cruisers with similar boat size and type, similar crew compliment, similar cruising grounds, similar lifestyles, etc... were cruising at that time. You'd then need to collect similar datasets. Only then can you start to draw any general conclusions.
... but interesting none the less. Thanks.
Actually, since you're so driven for hard data, why don't you make this your mission? I, for one, would value a statistically valid analysis.
