Marine Tools is an independent maritime project developed and maintained by one person. It brings practical calculation, planning and technical helper tools together in one place for seafarers.
The aim is to make common maritime calculations and lookups quicker and easier to access — without replacing approved navigation equipment, vessel procedures, professional judgement or onboard management systems.
This survey takes about 2–3 minutes. Your feedback helps guide future improvements and identify which tools are genuinely useful in everyday work at sea.
