Safety on board

- RAMBSS is a modular, stackable safety system for charging and storing lithium batteries for water toys on superyachts, with a capacity of up to 5.25 kWh per module.  
- The system mitigates the consequences of thermal runaway through temperature monitoring, charge cut-off, a fire suppression and cooling system, and a gas filter linked to an alarm.  
- RAMBSS has received type approval and will be able to meet the requirements of the UK’s MGN 681 for yachts 24 metres in length and over from 1 January 2027.

- Clear crew instructions before the manoeuvre improve safety and prevent a rush when mooring and casting off in port.
- The Voxtob Manoeuvre Box provides a hands-on visualisation of harbour manoeuvres, facilitates briefings and helps to engage newcomers in particular without the pressure of time.
- The Manoeuvre Box is no substitute for practical experience on the water, but it can help to structure procedures; the S version costs 49 euros, whilst the larger version costs 64 euros.

- Firemill is a compact CO₂ quick-response extinguisher for small, incipient fires, ideal as an additional galley extinguisher on motorboats.  
- Advantages: residue-free extinguishing agent, easy to use; disadvantages: extinguishing time of only around eight seconds, does not meet EN 3 fire-rating standards.  
- It is not a substitute for a standard fire extinguisher, is not suitable for engine rooms or confined spaces, and CO₂ poses a risk of suffocation below deck.

- Galvanic Voice aggregates NMEA-2000 data and issues alarms via voice output and a 360-degree LED ring with directional indication.  
- Four-stage alarm logic in accordance with IMO/IEC, acknowledgement via gesture; Integration of AIS, depth, engine, battery and anchor data.  
- Galvanic Pulse wristbands enable man-overboard alarms and watch organisation; the system costs approx. €1,130 and will be available from Q4 2026.

- The MediSee app provides digital access to the ‘Medizinisches Handbuch See’, with a focus on life-saving first aid and content that is easy for the layperson to understand.  
- Extensive content ranging from wound care, resuscitation, airway management and dental treatment to tropical diseases, including videos, audio and keyword search.  
- The free, German/English app works offline, allows users to add personal notes and is suitable for both commercial and recreational sailing.

- Hauptgefahren für den Antrieb sind Korrosion, Fremdkörper wie Leinen, Netze, Müll, Grundberührung, Bewuchs, Wartungsmängel und Bedienfehler.
- Regelmäßige Kontrolle von Propeller, Welle, Dichtungen, Lagern und Opferanoden sowie Reinigung und Schmierung beugt teuren Schäden vor.
- Im Notfall auskuppeln, Motor nicht neu starten, Ursache prüfen, Schlepphilfe organisieren; gute Seemannschaft bleibt wichtiger als Technik.

Checklist for boat owners: Everything you need to know about the propeller

- A 65-year-old woman fell overboard on Lake Constance during a storm and was found dead the following day near Langenargen
- Around 200 emergency personnel from Germany, Austria and Switzerland searched for the missing woman; the search was called off in the evening
- Lake Constance has a two-tier storm warning system with orange flashing lights; water sports enthusiasts are urged to pay close attention to these signals

- Following a line entanglement, there is a risk of hidden damage to the propulsion system, leading to vibrations, leaks and a loss of power.
- Specialist workshops recommend removing the propeller and shaft, checking for deformation and inspecting the coupling, gearbox, bearings and seals.
- Even minor damage can lead to imbalance and consequential damage, potentially resulting in a breakdown; repairs to complex propulsion systems can quickly run into five figures.

After the line gets caught in the screw: This needs to be checked

- If the engine stops suddenly because a line has become entangled in the propeller, ensuring the safety of the boat and crew takes priority over troubleshooting.
- Do not restart the engine without first checking it, as this risks bent shafts, faulty seals and creeping gearbox damage.
- Move the boat out of danger, disengage the clutch, pull gently on the line; otherwise, submerge the boat or seek towing assistance and head for the harbour.

- Grease fires on yachts often occur whilst cooking in the galley and are particularly life-threatening due to the confined space, heat, smoke and flammable materials.
- The biggest mistake in an emergency is to pour water onto burning fat; instead, switch off the heat source, smother the fire with a lid and cut off the oxygen supply.
- Prevention requires discipline: never leave cooking unattended, keep flammable materials away, brief the crew, keep fire-extinguishing equipment to hand and adopt a holistic approach to fire safety.

Risk of explosion: Never add water to oil!

- Morphéis is a GPS anchor buoy from Mooring Solution that measures the position directly at the anchor, thereby reducing false alarms caused by the boat’s swaying.  
- The buoy is secured by a Dyneema line with a spring mechanism, transmits a signal up to 100 metres to the receiver, runs on solar power for up to 72 hours and triggers an alarm if it drifts more than 4 metres.  
- The system costs €1,499 and is aimed at frequent anchorage users, whilst traditional anchoring apps such as Ankeralarm or Anchor Pro are significantly cheaper alternatives.

- The CO₂-powered Leak Stop Gun S seals hull openings in seconds using an EPDM balloon, replacing conventional leak plugs.  
- The standard LSG 150 balloon seals leaks measuring 50–130 mm; with the Flextube and LSG 400, openings of 120–350 mm can be sealed.  
- Housing (0.7 kg) made of stainless steel, aluminium or brass; suitable for use at depths of up to 20 m, temperatures from -15 to 95/100 °C; the device is reusable, whilst the balloons must be replaced after use.
