Thanks Charlie--I did goof and should have checked the link after it was posted. There was also a discussion of the life sling and its approval a few years ago:

This is from the PDF link I had meant to post @ LIFESLING® OWNER’S PREPARATION GUIDE Updated July 26, 2010
Developed by and for the Bonnell Cove Foundation's "SUDDENLY ALONE Seminar" which was first presented on April 7, 2001 in Mystic, CT.
Here is a quote from that link:
CHOICES. There are five Lifesling ® models in use in the US.
1. The original LIFESLING with 21 lbs of buoyancy, equipped with 150 feet of multi-filament polypropylene floating line. Recommended for 30-80 ft sail and powerboats. Meets ORC/ISAF Offshore Special Regulations (OSR) and
is USCG approved as a Type V device. (NO LONGER IN PRODUCTION - Replacement Storage Bags and Fiberglass Cases are still available).
2. The smaller, and less expensive
LIFESLING 2 with 21 lbs of buoyancy, equipped with 125 feet of multi-filament polypropylene floating retrieving line. Suitable for powerboats with a lifting point 10 ft above the water and sailboats over 20 ft LOA.
Meets ISAF OSR and is USCG approved (Type V which substitutes for a Type IV).
3. The LIFESLING 3 with 21 lbs of buoyancy, equipped with 150 feet of retrieval line for larger boats, stainless steel D-rings, SOLAS reflecting tape, and a rugged UV-resistant, fiberglass case.
Meets ISAF OSR and is USCG approved for both recreational and commercial vessels (Type V which substitutes for a Type IV) (New in 2006).
4. The LIFESLING for Commercial Vessels is similar to the Original LIFESLING with SOLAS reflective tape added.
Meets ISAF OSR and is USCG approved (Type V). Replaces the requirement for a 24 in ring buoy on uninspected commercial vessels that have a hoisting point at least 10 ft above the deck. (Replaced by LIFESLING 3)
5. The LIFESLING INFLATABLE (previously called RESCUESLING and INFLATABLE LIFESLING), equipped with 125 feet of multi-filament yellow polypropylene floating line, thrown like a softball that automatically inflates into a floatation collar with 25 lb buoyancy that functions similar to the original LIFESLING.
(Not USCG Approved) (Recalled in 2010 as not in compliance with new West Marine safety standards)
Based on this and the prior C Brat link, I went down to the boat to check:
I have a
Lifesling 2 This states on the device:
A. "Type V Bouyant Rescue device. This is Type V PFD because it has restricted approval. It is approved only as a substitute for a Type IV PFD aboard recreational Sailboats greater than 20 feet in length, and power boats with a lifting attatchment at least 10 feet above the deckwhen used in accorance with the manual....
D. This device is not intended to be thrown or used as a helicopter lifting harness.
G. CG approval number 160.064/3729/0
Thus it could substitute for a throwable IV device
if you have that lifting point. Very few C Dories would have that high a lifting point. I belive that the davit rig I have would qualify, if you considered the cockpit to be the deck (up and over the gunnel)--but we always carry several throwable cushions to be legal without debate.
