Personal safety gear

I'd like to adopt the requirements for personal safety gear on board Mercedes that the race committee specifies for the Race to Mackinac.  We may not need to wear every bit of gear for every race or cruise, but it's important to be prepared.  Here's a summary of what the requirements are:

1. Life jacket - Over the shoulders PFD with at least 33.7 lbs. buoyancy (inflatable), or inherently buoyant (non-inflatable) offshore life jacket with at least 22 lbs. buoyancy, both meeting U.S. Coast Guard or ISO specifications.  It should contain marine grade retro-reflective patches; have crotch or leg straps, whistle, and waterproof light; and be marked with your name.  Note that the inflating type does not need to be water immersion auto-inflating.
2. Safety harness - Integral built-in to the PFD or compatible with it (that is, wearing one doesn't interfere with the other). 
3. Safety tether - Not longer than 2 m. (6' 7"), minimum 4500 lbs. tensile strength, with snap hook on one end and quick release shackle on the other end that is releasable under load.
4. Knife - Must have a fixed blade or, if retractable, the blade can be opened with one hand. 

I know it's a bit of an investment to buy this gear if you don't have it, but it's for safety of your life, and pretty easy to justify that way!  I have recommendations for easy-to-use and comfortable products that comply with these specs (I've tried a lot of different brands) and where to shop for the best prices.  Let me know!
