Stuck in the middle with you

Something strange is occuring. In the last five hours the tide hasn’t moved at all. After a bit of research we discovered the Thames Barrier has a maintenance closure today and we’ll have no change of tide between 6am and 4pm. Which is fine, the barrier is great and everything, but I do wish they’d left us just a little bit more water before the closure. We’re just barely afloat and the wake from passing clippers is slamming the hull down onto the shingle beneath us. The noises are worrying.
