Navigating troubled waters can sometimes lead to unexpected encounters, as the owner of a French sailboat anchored in South Africa can testify. While we often talk about large cetaceans, sailing among hippos may require a few precautions to minimize risks and promote respectful coexistence.

Sailing boats and hippos: an unusual cohabitation, but one that exists

When you think of sailing in African waters, your imagination is filled with breathtaking panoramas and wildlife. Behind the apparent tranquility of the fresh waters of the rivers, but also the dirty waters of the marinas, lurks an unforeseen and sometimes deadly risk, linked to encounters with hippopotamuses. The experience of Basile and Martin, French yachtsmen based in South Africa, anchored in the port of Richard Bay, in the province of KwaZulu-Natal, reminds all sailors of the vital measures to be taken to prevent dangerous confrontations with these semi-aquatic behemoths.

Every day, on several occasions, the two freemen have to reach their sailboat with the help of their dinghy, while maintaining a high level of vigilance. Regularly, the hippos are there. They observe new visitors who come to disturb their tranquillity, generally keeping a safe distance from boats. Nevertheless, boaters have to adapt to their presence. Often, a simple turnaround is enough. Sometimes it's more of a scare," says Martin, one of the brothers: once, I was alone in the dinghy, and fear overcame me as the mighty lone male approached me... The most frightening situation occurs at night, when their presence is hidden from our eyes. Hippos can launch swift, fatal attacks in a matter of seconds; it's a remarkable fact that I'd never imagined .

Rules to avoid confrontation with hippos

As you'll have gathered, these massive, seemingly tranquil creatures are endowed with surprising strength and velocity, making them formidable adversaries in the event of a confrontation. Here are a few essential tips for boaters who frequent these brackish waters, to minimize the risks and sail in harmony with the local fauna:

1. Maintain a respectful distance: Although hippos may appear peaceful on the surface, it's crucial not to get too close to them. Don't block their path, and keep a respectable safety distance to avoid disturbing or frightening them.

2. Avoid sudden movements: Sudden movements can be interpreted as a threat by hippos. Refrain from any precipitous maneuvers or loud noises that might provoke them to react aggressively. Do not intentionally disturb them or attempt to feed them.

3. Stay away from young people: Hippos can be particularly protective of their young. Avoid approaching young hippos, as this may provoke an aggressive reaction from the adults.

4. Watch out for areas known to be home to hippos: Check with local authorities or residents to find out where hippos are accustomed to roaming. Avoid these areas if possible, to reduce the risk of encounters.

5. Daytime navigation : Hippos are most active at night or at dawn. Use caution when cruising after sunset, and prefer daytime travel to minimize the chance of encountering them.

6. Stay tuned for local wildlife: Nearby animals can often give clues to the presence of hippos. If you notice any signs of disturbance among birds or other animals, be on the lookout.

7. Prepare for emergencies: Even if you take every precaution, an unexpected encounter could still occur. Make sure you have means of communication and signalling devices. If you feel in danger, or if the hippos show signs of aggression, leave the area in question without haste.

By navigating with care and respect, you can immerse yourself in their environment without endangering the hippos' safety. These basic rules are the same as for large marine mammals.
