Great post Brad. Interesting stuff you presented. very glad to hear it worked out well for you.
There were a few on here who really gave me an extremely hard time and lit into me for staying on my boat through the storm and I was tied up in my slip even. Were you glad you stayed?
Yes, but keep in mind that I was 100 miles from the hurricane. The boat is not my home, so I would leave if the hurricane was going to hit directly. (From reading online recaps, that seems to be a major factor in people's decision, whether the boat is their home or not.)
Your post is great as it give us great information should we ever need to rig for heavy weather. I am particular interested in the advantage of the three anchors as opposed to two. Did you feel that the potential strength of the storm was the reason for the three system. Maybe i didnt read it correctly. It seems the 2nd and third anchors had substantially different lengths of line/ chain, more than the varying depths would cause. Is that to maintain the correct angles? During the storm did you have to go topside and adjust from time to time as the wind kept shifting?
No adjusting needed. The different lenghts were more a factor of the surrounding mooring and navigation buoys in that tight space, and setting the lenghts so the boat was right where I wanted it.
I could have done it with 2 anchors, but in a blow it's best to have extra anchors out, IMHO, in case something happens to one of them. If you don't have a lot of swinging room, 3 anchors (set 120 degrees apart) will keep your boat swinging tightly around one spot, as if it's on a mushroom style mooring. For the storm, I took into account the expected wind direction and dd not put them 120 degrees apart, but if the winds were forecast to clock around more, I would have.
Hope that helps.
