5.0 Stars
Maritime Master Knots teaches real ropework with real-time 3D. Every knot is rendered as animated rope you can rotate, zoom, and scrub from the first loose turn to the final dressed knot, so you see exactly how it forms instead of guessing from static pictures.
It is knot tuition the way it should be: watch it form, follow the steps, understand where it is used and where it fails, then practise until your hands know it without thinking.
Watch Knots Tie Themselves in 3D
A custom rendering engine draws every knot as smooth, physical rope in real time. Drag through the tying animation at your own pace, orbit around it to check the lay from every side, then follow the numbered step by step instructions until it is muscle memory.
Forty Two Essential Knots
The library spans fourteen hitches, thirteen loops, five bends, four stoppers, and a set of utility and decorative knots. Learn the bowline, clove hitch, sheet bend, figure of eight, round turn and two half hitches, rolling hitch, prusik, alpine butterfly, and monkey's fist, along with the rest of the working sailor's repertoire.
More Than Instructions
Every knot comes with its uses at sea, safety warnings, strength and difficulty ratings, history, memory aids, and its reference number from the Ashley Book of Knots. Where a knot relates to the COLREGs or day-to-day seamanship, the notes tell you how and why.
Find It Fast
Search by name, category, or Ashley number, pin favourites for the knots you are drilling this week, and study fully offline with no account and no tracking. The app is localised into Spanish, French, German, Japanese, Chinese, and Portuguese.
Practise Safely
Knots are safety equipment. Practise with real rope in a controlled setting, inspect your line before use, and never rely on any app alone where a knot bears load or protects life. For climbing, rescue, and working at height, always get qualified in-person instruction.
Who It Is For
For sailors, motorboaters, anglers, scouts, riggers, and anyone who loves good ropework, from first bowline to advanced splicing curiosity. A perfect companion for sail training and skipper courses.
Part of the Maritime Master Family
Round out your seamanship with Maritime Master Skipper for navigation theory, Maritime Master for all-round learning, and Maritime Master IALA Buoyage for the marks you will pass on the way out.
Frequently Asked Questions
Do the 3D animations need an internet connection? No. Everything renders on your device and the whole app works offline.
Can I learn climbing or rescue knots from the app? The app documents such knots for educational purposes, but load-bearing and life-safety use always requires qualified in-person instruction and proper equipment checks.
How are the knots organised? By category: hitches, loops, bends, stoppers, utility, and decorative, each searchable by name or Ashley Book of Knots number.
