Costs are in US Dollars

Note: These numbers reflect great variations in fuel costs and consumption, and may not be true for a vessel you have in mind. Also, you should not assume that a trip run in the opposite direction will cost the same. Panama to Tahiti, could be done in 4-5 weeks instead of the nearly 8 that it took the other way. In addition fuel is about $4.30 cents a gallon now, versus up to $1.50 just 2 or 3 years ago when some of these trips took place. For a big powerboat run fast, fuel is the largest part of the cost. Assume about 50%-80% more than the numbers above for trips to be done presently.

Estimates base upon the table above for a trip today.

One final note: these numbers include everything expended for making the trip.

In summary
The cost of a delivery can vary quite a bit. To make an efficient plan(low cost), requires knowing details about the route and vessel. With this knowledge in hand it then becomes possible to make a plan which holds the costs to the minimum, with due consideration for safety.
