My 320 has the stainless steel arch along with a large bimini that precludes easy access to the the traveller. Often when I tack the mainsheet somehow becomes wrapped around the traveller block. I then have to climb rather precariously along the arch and untangle the mess. This often involves quite a stretch and the risk of a swim. Having the sheet under load at the time certainly doesn't help matters. I've thought that sheeting in the main as I tack and then letting it out again may solve the problem but that certainly complicates the act of tacking singlehandedly. Any other thoughts?
