Tropical storm approaching and on my mooring

[svinvictus2]

Put your Racnor out at a 180 degree angle to the mooring with all your chain. You should be fine.....
Get rid of the poly as soon as you can!!!!!!!

20kg Rocna sounds good for a 33ft mono.
20mm Nylon with splice extending over the chafe area and no fire hose is better. Much less stretch in the splice zone so less heat and chafe. Other end of the nylon in the water so well lubricated and cooled.

Very good comments. Thank you.

I added a 1 inch 3 strain poly line. Breaking strength is 27000 lbs. I used firehouse at the cleat to deter chaffing. I made this rope a little longer than the 3/8 thinking that the 3/8 will stretch and then the inch will come into play. Stayed on the screw, all of the chain is 3 weeks old, so not worn or any barnacle growth. 97i is at 13 degrees now, we are 12. So the impact will be less than originally expected, that can change in a hurry though.

My intentions have been to stay on the mooring up to and including a Cat 1. Over that I leave the island to points west or south. Depends on the storm. I will post the results of my decision as they occur. All is very calm now, 9:00 pm.

You (and others) should understand the characteristic's of the rope your using. 1. Nylon 3 strand will give about 10% stretch (elasticity) and not lose strength. Nylon 3 strand is the best option for anchoring and mooring. poly and poly blends are less elastic, breakdown faster (weaken) and are typically weaker in tensile than nylon. I am assuming your boat is no more than 12k-15k lbs so the 1" poly should be fine as long as you have some elasticity in your set-up. (snubbers do very little for elasticity)

Just read Noaa as of 2 am est. Winds to 35 knots plus gusts. 90 percent chance of forming a cyclone. It is not named yet, which means my deductible has not gone up yet. My friend in Bequia not to worried and is hoping for rain. He lives ashore
