Daysailor size catboats often uae two eyestraps with a 7x19 stainless steel wire bridle with trimbles and clamp on each end.
Most people make their own from oak or ash.
You can cut the blanks out very quickly by cutting out the side profile and then the top profile on a bandsaw, then drill two holes for the fasteners. What takes time is whittling and sanding the rounded over edges and varnishing them. I'm making some cleats for the Joel White MarshCat I'm building for myself right now. I'm glad to help any lady taking on her own boat project. Good luck and hang with it.
