Yes, you read that title correctly! Sailing can be a very dangerous sport as it is, but I cannot imagine increasing that danger by sailing if you're blind! This couple is amazing to me with their determination to maintain their independence regardless of the fact that they're blind.
Sailing in fog can be quite concerning in itself and feels strange to not be able to see, but again sailing while blind -- they are very brave! If it weren't for instruments to help guide their way, I have to wonder if they would have pursued their dream.
Unfortunately, the video story about the couple sailing blind was no longer available, so I removed the video from this article.
