WHY MARINE TOOLS
Designed around practical maritime work.
Marine Tools brings frequently used calculations and technical helpers into one consistent interface. Students can focus on the inputs, assumptions and results instead of spending time switching between unrelated calculators.

Vessel Profile
Save reusable vessel, machinery, tank and energy-carrier data so exercises can use a consistent vessel setup.
FOR EDUCATORS
Use it as a supplement — not a black box.
Marine Tools works best when students are asked to understand and validate the calculation, not simply copy the output.
Set a practical exercise
Give students realistic vessel data and ask them to calculate fuel use, endurance, tank quantities or electrical values.
Compare methods
Let students solve the task manually first, then use Marine Tools as a control or discussion point.
Discuss assumptions
Change speed, density, consumption or weather inputs and discuss how assumptions affect the result.
Send feedback
Students and instructors can suggest improvements and missing tools directly to the project.
BUILT FOR PRACTICAL USE
