After yesterday's eclipse by the supermoon, we now have a supertide. A super-low tide, coming in at 0.0 feet above chart datum. My usual passtime during a springtide, looking for shellfish on the bottom of the harbour, yields nothing. The critters stay hidden in the mud, and just spit water 3 feet in the air!
Meanwhile on the slipway, the fishingboat that got its nets snagged by an U-boat of unknown origin. The encounter caused £10k worth of damage.
