Many thanks Julian. I think you are absolutely correct. Fully unwound the drum and retied the line length. So far this strategy has provided full up/down transition without any trip out. Initally I kept the same line length with some tension – which did not work and tripped out. With the heavy transom I assume the problem still occured when not wrapped with heavy load. Thank you so much for the response – very grateful to a problem solved. Best regards, Chris.
