I agree, the cascading tackle is a viable option but somehow I always think of them on sport boats with very bendy masts in moderate conditions. Probably silly but that is what comes to mind. Not sure I would trust a cam cleat but again, that’s my own phobia.
Personally I would just put a new hydraulic unit on and go sailing. Takes your pick on brand.
