SeaWise practical guides

Practical, source-conscious workflows for reviewing inputs, comparing alternatives and checking results.

• A voyage fuel estimate you can check

  Build a traceable voyage fuel estimate from distance, speed, burn rate and price, with a worked example and a review checklist.

• Compare passage speeds using your vessel’s fuel curve

  Use measured consumption at each speed to compare voyage time and fuel cost without assuming that faster or slower is always cheaper.

• Review planned versus actual voyage fuel

  A practical post-voyage review that separates route, time, consumption and price differences before changing the next estimate.
