First, the yacht doesn't capsize. It is balanced by a keel located beneath the yacht. This keel acts as a counterweight, typically measuring 2-3 meters in length and weighing 5-7 tons.
Second, we always sail along the coast. At night, we anchor in sheltered bays or marinas.
Third, if there's a forecast of bad weather at sea, we don't go out.
Fourth, the yacht is equipped with safety equipment including life rafts, life jackets, dinghies, distress flares, and radios. Even in the unlikely event of an emergency, help will arrive swiftly.
And fifth, if you don't experience motion sickness in a car, with adherence to safety procedures, you'll feel great on the yacht.
