I recently bought a used Core Sound 17 and have no experience with Cat Ketch rigging. The boat has aluminum masts with tracks, sprit booms and sails with two reefing points. It was built in 2015 (probably started around 2012).
Think I have most of the lines figured out but am puzzled about where the main sheet blocks of both mizzen and main should attach. The main sheet blocks have snap shackles attached so they may have been snapped to the sail or sprit. Sprits do not have any hardware other than spotters. Any ideas as how to secure mainsheets to sprits or sails is very appreciated. Looking forward to my first sail.
