We have a Yamaha 25-II, we are fairly new to sailing. Looking for either a member who is experienced at/possibly willing to climb our 30’ mast, or if anyone has a good reference for someone we could hire. We are trying to install a Tides Marine mast track and there is a stopper (two screws holding) 6” below the top of the mast groove they want us to remove. Thanks. Chris (& Linda) Loughran.
