Actually I have a titanium shackle --and use it elsewhere. This Sabre is a sweet boat but every upgrade has it price beyond the initial cost. The original owner had Sabre put in a removable stay sail stay and that required the anchor locker to be moved forward to the extent that the custom made bow roller designed perfectly for a CQR now placed the shank of the CQR back over the locker hatch making the locker unable to be opened and the anchor sliding around. The genius solution was to go with a Lewmar Delta which was undersized. Now am wrestling with this Manson and trying not to have the shank hit the underside of the roller furling. hope to see you this season. We will be in Maine most of August. Doing long weekends until mid July. How are your blue cobalt sockets holding up?
