In the light of day

It was a dark and stormy night. The wind came from an unusual direction, sou'west. In the pitch black all I could see was white caps breaking and spray hitting the windshield. The waves got bigger closer to the protected gap between the islands. The wind now blew directly between. White caps where calm waters prevail.
It was hard to dock with waves breaking along the dock. With a head lamp on I managed to find extra lines to tie our boat more securely to the dock and then to Tom's boat and checked the lines on Cathy and Roger's. Then wobbled my way along the heaving dock and up the ramp and was happy to get home.
Half an hour later Roger phoned 'the dock is gone!'.
The coast guard was called and came to find the dock broken in two. The end with the boats was fine and near where it usually floated being anchored with new chain but the shore end had split, jacknifed and was blown down to the next dock. The ramp now rested one end on shore and the other below the water.
I suppose I should have used those extra lines on the dock rather than the boats.
