A Catalina becomes entangled with a daymark just outside the Alameda Estuary. Below, the mark on the chart.
In the past couple of weeks Temerity destroyed two sails (a 0.6 oz spin and the kevlar main) and developed major issues with the brand-new lower rudder bearing, necessitating a haul-out. So I can really feel for this guy who snagged his furled headsail on a local daymark and took out his mast. No wonder sailors drink!
