Assuming 2 bow cleats

cleat a line, pass through the pendant loop and cleat to the opposite side. Repeat with another line going in the opposite direction. The boat should be wearing a necklace now. Then, this may be stupid, I tie the ends together with reef knots. I think the front of the boat will have to shear to loose this setup.

That's what the charter company taught us to do so I figure they're fairly concerned about their 1/4 million dollar boat in the hands of an unknown. If one line goes down, the other is still there. The thrust should be down on the entire bow, not sideways on a single cleat.
