Reddit mentions of Astral Buoyancy V-Eight PFD - Unisex

Update:

The bottom is a hard line keel for both the Pungo and the Loon. The Loon has sloping sides, whereas the Pungo is hard-chined. I wouldn't think there would be much performance difference, but the stability of the Pungo could be a bit better. Don't have pics of that.

I have had the Loon out on the water like 5 times now. It handled the first time with a bit of chop pretty well. Then three of the times, in placid water, it was so sleek it was like a dream. The other time it was in moderate chop, it did feel stable, but I didn't venture too far from shore.

It tracks very well, turns on what to me feels like a dime. My friend had a LL Bean Manatee (10') and I easily went in circles around it in terms of speed and tracking.
Here are two other pics for reference on the water. I like the side view because it shows how low in the water it sits. I believe this is good for flat-water kayaking since it reduces the wind drag. It moderately protects against water coming over the bow, but I'm sure a touring or sea kayak would be better in that department: http://imgur.com/a/N617B

Finally, it is soooo comfortable, at least compared with numerous rental boats I've tried over the years. I could sit in it for hours. Width and length are great to stretch out, and the seat is awesome. I'd recommend getting a high back PFD. I literally tried 5 of them with the kayak, and the two best for me were: Astral http://amzn.to/29rVAMB and Onyx: http://amzn.to/2920ZrR (the one I bought)
