In the bay I use 4:1 when anchoring on chain when in 'protected' waters.
10:1 in Rock Creek or Swan Creek because of the very thick soft mud, the back to 4:1 after the anchor has 'settled in'.
Attachment of the bridle is quite fast/easy. The bridle 'legs' are premarked .... I set the anchor, attach the bridle from the bow(sprit) to the rode and then simply let out more rode, and make a final adjustment of the bridle if the 'connection' is off or not AT the waterline.
Whats also good about a bridle is that you can hold an 'offset' from dead into the wind/waves, especially good when the waves are deflected around a corner, etc. and the wind 'isnt'.
With all chain and a chain hooked bridle you really have to be concerned with topside damage ... simply plan so the hook is clear.
