While it is extremely rare for a Venetian gondola to tip over, it can happen if passengers do not follow safety instructions. Gondolas are designed with a specific asymmetrical shape to counter-balance the weight of the gondolier standing on the back, making them surprisingly stable for such narrow vessels. However, they rely on a delicate balance of weight onboard. In December 2023, a famous incident occurred where a gondola capsized near St. Mark’s Square because a group of tourists refused to sit down and stop moving around for selfies while the gondolier was performing a tricky maneuver under a bridge. Because of such incidents, the gondoliers' association has strictly enforced capacity limits (reduced from 6 to 5 people for standard tours). As long as you remain seated and follow your gondolier’s guidance—especially during boarding and when passing through narrow canals—the chance of a gondola tipping over is virtually zero.
