the best of conditions. I would suggest a mechanical solid vang by Garhaur Marine in Upland, Ca. Give him your measurements and he'll build you a custom fit one out of high grade SS and ship it to you. Your sail handling problems, what ever they are, would be greatly reduced. A Garhaur vang and a Lazy Cradle and your problems just went away. He's a great guy and does excellent work. www.garhaurmarine.com.
