Part of the Trident: we don't buy it tour blog 
After sailing around a substantial chunk of the UK's coastline - via Leith and then Greenock - we've finally reached London. I've entered the city by train, car, bus and bicycle before but I have to say, sailing into London beats them all. We slipped through the Thames Barrier and up past the Millennium Dome, Canary Wharf and the Docklands to our mooring spot by Tower Bridge, where we settled in and watched the lights come on over the London skyline. We're just 100-odd metres from the bridge so give us a wave if you go past (or better still, come and have a free tour of the ship this weekend - more info below)!
Just up the river is Westminster, where, on the 14th of March, the decision will be taken on whether to replace Trident. It's a once-in-a-generation decision - and there's £76 billion and a potential new nuclear arms race at stake. We’re here to drive the message home to Westminster that Trident's illegal, immoral, unwanted - and a monstrous distraction from the real threat: climate change.
This afternoon, London Mayor Ken Livingstone will be joining other well-known folk onboard the ship, adding his voice to the growing opposition to the rush to replace Trident. Annie Lennox, Bianca Jagger, Tony Robinson, Anita and Gordon Roddick and Major-General Sir Patrick Cordingly will all be having their say on board - please don't forget to have yours.
At the weekend, we're having two open boat days, which means you can get a tour around a working Greenpeace ship. Come along to Thames Quay, Marsh Wall on the Isle of Dogs (E14) between 11am and 4pm on Saturday 10th or Sunday 11th March. The nearest station is South Quays DLR and the D8 bus goes straight there. Oh, and it's free!
