Here are the parameters:
1. You don't want to rent one just like you never lease a car, You like to keep it until you die
2. Your likely cruising areas are Northern Atlantic from Boston to Europe and from N30 to S30.
3. Self righting is important since you are likely to be alone or with just one crew.
4. You need and are willing to survive for a week in Hell before rescue. Toilet paper is not essential to you.
If you are spend the money to get a life raft now, which one will you buy? Please also share links for good reviews on Life Rafts, particular from Practical sailors. I have their subscription, but I can't recall one from them.
Avon makes nice ones!
