Capt Rich,
Interesting about the flotation provided by the two PFDs you own. I assume you are comparing a "type1 inflatable PFD" with a "type1 regular PFD", or a type2 with a type2? Comparing a type 1 against a type 2, or a type 3 against a type 2, would be apples to oranges.
According to the information I come up with,
the required minimum, is 50% greater for a type1 inflatable PFD, compared to the required minimum for a type 1 foam PFD.

TYPE I
Type I PFDs, are the most buoyant PFDs and suitable for all water conditions, including rough or isolated water where rescue may be delayed. Although bulky in comparison to Type II and III PFDs, Type I will turn most unconscious individuals to the face-up position. They range in sizes from adult to child.
US & CAD - Inflatable Type I PFD Minimum Buoyancy: at least 33.7 lb (150 Newtons)
US - Foam Type I PFD Minimum Buoyancy: 22.5 Ibs (100 Newtons)
CAD - Foam Type I PFD Minimum Buoyancy: 15.51 lb (69 Newtons)

Type 2 and type3 PFD numbers are similar, with the inflatable version in each type having a greater minimum buoyancy required.
Once you’ve decided to purchase a Personal Flotation Device (PFD), and that should be an easy decision, the next step is to figure out which one is right for you. Visit us here for a complete list of PFD Classifications.

I just checked the inflatable I own and it provides 35 lbs of buoyancy (which is over the min. requirement).
How does that compare with the "regular" PFD that you own and use? (just curious)
