Thanks for posting the video and sharing all of the solid analysis on preventers. We are just “redesigning” the preventer system on our OVNI 495 based on improved load calculations, but the question not well answered (or i have missed it) is what is the best attachment mechanism between the boom line and the rest of the preventer ? Based on strength requirements: (1) a knot seems like a bad idea:(2) , a snap shackle would need to be huge; soft shackles (which we are presently using) are cumbersome to attach/remove with cold wet hands.
Any thoughts and observations ?

Hi Steve,
I will be covering that, and much else in Part 3 next week.
