Little Venice in West London is among the city's most popular boating locations. A sharp increase in the number of Londoners living on the water has put pressure on the local boating community.
"Over the last five years it has gone absolutely crazy," says David Akinsanya, who has spent 17 years on the canals, but rarely stays in London due to overcrowding.
Most of the new arrivals receive "continuous cruiser" licenses that require them to change location every 14 days. The most popular areas in east and central London see heavy congestion.
Wealthier boaters can secure permanent moorings in desirable locations for over £1,000 ($1,320) a month, although space is at a premium.
Many boaters blame the Canal and River Trust, which manages the canals in England and Wales, for failing to prevent overcrowding. Short-stay facilities around the Olympic Park have been reduced.
Tensions have arisen between boaters and the population on land in some places. In Islington, London, locals have complained about noise and pollution from boaters, and succeeded in placing restrictions on their numbers.
