NATARAJAby Techvein
For cadets, officers and Master candidates

Thirty days, everything open, no card

Create an account, verify your email, and every one of the 60 laboratories is unlocked. Not a sample. Not three labs and a paywall.

This is a course from cadet to Master, and the product knows which one you are: pick your rank when you sign up — deck rating, cadet, Third or Second Officer, Chief Mate, Master Mariner — and it is what the interface calls you from then on. You can change it, and add a photograph, from your profile at any time.

Three things nobody else will tell you

It keeps working afterwards

Nothing switches off when the month ends. Your access continues; the upgrade prompts simply become more visible. This is unusual and we would rather say it plainly than let you discover it.

It works with no signal

The platform is a progressive web app. Once it has loaded it runs offline — written for reading on ship satellite links and in colleges where the connection comes and goes.

Every solution, line by line

The exam room holds “the Fifty”: forty navigation numericals plus ten in stability and cargo. Every answer key is engine-proved and every solution is worked out in front of you, not handed over as a final figure.

Try it before you sign anything

Here is a real panel, right now.

Tropical revolving storm — MT-05

Highest-stakes topic on the paper. Move your ship and read what changes.

Two things we will not pretend about. Meteorology numericals are not in the exam paper yet — they are being written. And every laboratory carries a practice — not an approved assessment marker, because that is what it is.

Two doors, and you should take the right one.

A cadet or a serving officer starts free and is inside a laboratory in a minute. A college talks to us first, because enrolment and faculty tools need setting up properly.
