Wat back when the kids were still young we went fishing down at Port Aransas. We were in the boat near the end of the jetties ,anchored off with a bow line and maybe 75 feet of line.We were fishing for sheephead near the rocks so I dropped a stern anchor to keep us in one spot, just straight down. A coast gaurd cutter came through, kinda close pushing a helluva wake. The first wave hit and I realized the anchor was hung up and water came over the stern, the second wave was much larger , I had my knife laying out I was using for cutting bait. It was sharp. I used it to cut the anchor line before the wave hit saving us from being swamped and sunk. Since then I always keep an open ready knife anytime I am boating.
Not a knife story but a friend was at the fuel dock
on the lower mississippi when a tanker came up river
The bow wave sucked all the water away from the dock
his 24 foot boat went under the dock and then the water
came back up , crushed the top and console. he was lucky
to be in the cockpit. A real nightmare.
