We were on a 2017 50ft Saba, "Liberty" from BVIYC. Overall, this is a fantastic cat. Beautiful, sails fast, very efficient 75HP diesels, a great generator that sipped a little over 1/2 gal per hour loaded up pretty heavy. There were 11 adults on the boat and honestly, everyone was very happy. Lots of room to spread out.

All of systems on the boat worked very well except for the very quirky system of attaching the hook at the head of the sail to a headboard car on the mast. This turned into a major PITA. The system never did work correctly. I was up in the stack pack several times trying to connect or disconnect. Hopefully the system on Katrina is working properly.

This is taken off of page 15 of a Saba 50 owners manual that I found online at:

Hoisting the mainsail

2) Using the green handle, bring the stainless steel hookinto contact with the headboard car
Pull sharply the handle in order to hook the mainsail head onto the headboard car
3) Store properly the 2 handles ( red and green) into the pocket , that avoids the hook lines getting trapped into the standing rigging or the lazy jacks.

4) Hoist the main sail
Lowering the mainsail
1) Bring the mainsail down to until you can reach the hook handle pocket and bring out the red handle
2) Pull sharply onto the red handle to unhook the mainsail
3) Lower the rest of the mainsail, the head batten will stack properly along
