Just to have it right: with bridle you mean forestaybridle?
So this dock line goes from behind to the front and is hanging overboard when needed? Is there one line in the middle or two each on the side?
Yes, to the forestay bridle. The line runs under the trampoline and is always in place.
I use just one line, along the port hull, because my spinnaker gear takes up too much room on the other side.
If you use just a bowline and loop and the boat has any headway, you end up being dragged under the boat.
It is easy to become fatigued so practice your plan and learn it well so you can reboard quickly.
