Marcs question was how did he lose the fish on a run into the wide open. He didn't lose it in the rocks. How to land fish around boulders and other structure such as pilings is another topic. Maybe I can get some time to write a too technical post about that too!
In short , my philosphy around boulders is to use a longer rod (I like 10.5 to 12 feet) , an oversize leader (50 LB Ande) , and high test running line. Choose you perch carefully , and be prepared to "put the boots" to the fish if needed.
Sometime I'll have to tell the story about the Mexican Standoff I once had with a big fish at Fresh Pond Rocks. I was praying for the tide to go out that day!!
