Real Scenarios. Real Solutions.

Here are just some of the ways NautiSuite works for you — on the water, at the mooring, and ashore.

anchorAngel
⚓ anchorAngel Peace of Mind at Anchor or on a Mooring
  • Mooring or marina peace of mind. You leave your boat on a mooring buoy or in a marina berth and want to be instantly notified if it moves for any reason — dragging, a failed mooring line, or if (heaven forbid) it was taken.
  • Overnight anchorage. You anchor in a sheltered bay for the night. Anchor Angel monitors your position while you sleep and wakes you the moment the boat drags beyond your set radius.
  • Anchoring in tidal streams. You anchor in a tidal area where the boat swings significantly. Set a custom watch radius that accounts for the swing, so you only get alerted if the boat actually drags. and get instant feedback about speed-over-ground (SOG) and course-over-ground (COG).
  • Leaving the boat unattended ashore. You go ashore for a meal or a walk and want confidence that if the anchor drags or a mooring fails, you'll know before the boat ends up on the rocks — even with your phone in your pocket. *requires a multi-device subscription
  • Storm or squall warning. A weather system passes through while you're at anchor. Anchor Angel runs silently in the background, screen off, and alerts you the instant the boat moves outside your safe zone.
myTides
🌊 myTides Planning Around the Water
  • Passage planning. You're planning a coastal passage and need to know the tidal window for crossing a shallow bar or transiting a tidal gate at the right state of tide.
  • Drying harbour entry. Your destination dries at low water. Use myTides to find the precise window when there's enough water to enter and leave safely.
  • Fishing or leisure timing. You want to be on the water at the optimal tidal state for fishing a particular mark, or simply want to time your trip to avoid a foul tide.
  • Checking conditions before departure. You glance at myTides each morning to see the day's tidal range, times, and heights at your home port before deciding whether to go out.
  • Kayaking, rowing and paddleboarding. Planning an evening on the water in a kayak, rowing boat or on a paddleboard? Know the tides before you go. Whether you're crossing a harbour mouth or paddling a tidal estuary, myTides tells you exactly what the water will be doing — so you stay in control and don't end up losing a fight with a foul tide.
launchWindow
🚤 launchWindow Slipway and Tidal Quayside Launching
  • Trailered boat on a tidal slipway. You tow your boat to a tidal slipway and need to know the exact window when there's enough water depth to launch and recover safely, based on your vessel's draught.
  • Tidal quayside access. You need to bring your tender or dinghy alongside a tidal quayside and want to know when the water level will be sufficient to do so without grounding.
  • Planning a day trip around the tide. You want to launch at a specific time and need to confirm the tide will be high enough — and that you'll be able to recover the boat before it drops again.
guardianAngel
🛡 guardianAngel Safety and Grounding Alerts
  • Navigating shallow or unfamiliar waters. You're exploring a new anchorage or creek and want an alert if tide range might pose a risk of grounding. Drop anchor or pick up a mooring, enter the depth and get instant feedback.
nautiAcademy
📚 nautiAcademy Maritime Knowledge and Enrichment
  • Brushing up on the COLREGS. You're preparing for a day sail and want a quick refresher on the collision regulations — who gives way in which situation — before heading out.
  • Learning at your own pace. You're new to boating and use the bite-sized modules and quizzes to build your maritime knowledge gradually, tracking your progress and trying to beat your previous scores.
  • Keeping skills sharp over winter. Your boat is laid up for the season and you use nautiAcademy to stay engaged with seamanship topics so you're ready when the season starts again.
  • Sharing knowledge with crew. You challenge your crew to complete a quiz before a passage, making maritime awareness engaging and competitive.
  • Preparing for a recognised qualification. You're planning to take an RYA or similar course and want to arrive with the theory already second nature. nautiAcademy builds instinctive responses, maximising your chances of success and value for money.

Know Before You Ground

Intelligent grounding alert system that monitors water depth against your vessel's draught in real time. guardianAngel gives you clear visual depth analysis and instant alerts — so you always know when you have safe clearance, and when you don't.

Never Miss Your Launch Window

Calculates the optimal windows for launching or recovering your tender or dinghy from a slipway or tidal quayside, based on tidal height and your minimum launch depth. Morning and afternoon windows clearly displayed — so you plan your day around the tide, not the other way round.
