Traveling from Avalon Harbor to Isthmus Harbor on Catalina Island, a distance of about 12 miles, there is a good breeze from the stern (about 10 degrees starboard) with a following sea with about 6 foot docile swells. The main is up and out however am also motoring to maintain hull speed so I can reach Isthmus before dark (late start).Jib is furled due to being cantankerous with a stern wind.A large trawler overtakes me on the port. There is a big wake that eventually catches me. So as not to have the boom swing around and everything rocking back and forth (no side resistance with main swung way out) I sheeted the main to prevent wild jibe and cut about 60 degrees to port. The wind turned out to be sizzling at about 25 knots (guessing) however I didn't realize this as the apparent wind was less due to motoring.(the folowing happens in a span of about 10 seconds) She heels over so dramatically that I have to brace with my legs in the cockpit while working the tiller to try and steer back to the original course. However the rudder is useless and only pushing the bow into the water.We hit the wake and the keel comes out of the water momentarily between the waves. The mast hits the water, I fly into the lifelines and everything not nailed down hits the cabin side.The boat stops and then rights itself. I steer back on course. No damage except a huge mess inside even though everything had been (so I thought) stowed or secured.Where were the mistakes?
