RE: [Paddlewise] Rolling Your Sea Kayak

If one of you guys are over 8 feet tall, perhaps this would be an
issue---for most people 6 feet tall and less, the pressure difference of
less than one foot to your diaphram, would be too small to be an
issue---over expansion injuries could occur if you took a full breath 5 feet
down ( I mean your chest is five feet down ) and then held it to the
surface. But this is a much different scenario.
I don't see how a snorkel could come close to providing equivalent emergency
air, particularly in rough water. And remember, I freedive,  which means I
like snorkels :-)

Regards,
Dan

We had a discussion about the use of a pony or spare air for rolling and I
believe someone (could have been me) suggested that one could embolize if a
full lung of compressed air was taken while upside down. I don't think the
risk is worth it, as a snorkel type device would be much safer.
