I have a couple more considerations for you in addition to the good advice you have already received:
1) If you are using your bow anchor
with all chain rode
and don't already have a bridle
, make sure you install an appropriate length stretchable bridle
[e.g., nylon 3 strand...] on the chain so you aren't putting those surge loads on the anchor
... [I'm sure you don't want the quay moving toward you...]
2) If you don't already have springs or rubber snubbers on your stern ties, and if they are double-braid, consider replacing them with 3-strand nylon as well.
To increase stretch [and strength] in times past I have had success tightly twisting two lengths of 3-strand nylon for each tie. That improves strength and give you a quick way to add some stretch if you have no alternatives at the moment... [One method is to secure the middle of a long enough length of 3-strand to the quay, then lead the 2 bitter ends to the boat. Twist the two secured lines together from the boat as tight as you can and cleat it off as a single
line. Repeat for the other shore ties.]
I suspect these may all be things you already do, but I mention them just in case and for future readers to consider...
It sounds like it is not an ideal day for baking that soufflé... I hope it ends soon for you...
