It takes a lot of guts to be as honest as you were about your experience. It means that you will learn from it, and you won't make that mistake again. I'll bet next time you leave that bag of leashes, you will turn around and go get them! Someone posted something about keeping your head over the top of your yak. This is sooo true. When I flipped in open water, it was because of water in my hull (due to eating it in the surf...), AND because I leaned over to do something and you would be amazed at how EASY it is to flip. Also like someone else posted, the ass is the center of gravity in the yak.
Sorry about your gear, I'm happy you are OK. Yes, it is depressing, and discouraging, and humbling. This is the most amazing type of fishing I have ever done, and also the most heartbreaking at times! just don't stop!
