Tonight in a new experiment I tried paddling with my eyes closed for an extended period on the ocean, like 1 minute at a time. We had 1-2ft wind waves with 3-4 foot ground swell, and it made for quite a disorienting experience!
When the smaller 1-2 foot wind waves passed, it was fairly easy to maintain normal paddling, as the boat rides over smaller waves without much effect to the pitch and roll of the boat. The larger swell was coming in 7 and 14 second sets, and when the bigger stuff passed and combined with the wind waves it was a crazy ride! I had to brace a few times but never swam - it felt like a roller coaster and at one point almost felt like free fall a couple times as a particularly steep and bumpy set came through! With my eyes open, the conditions were no problem at all, but eyes closed is totally different!
I also developed some slight seasickness, but nothing bad once I opened my eyes.
I was able to maintain relatively good directionality because the sun was setting, and luckily my usual route is nearly straight west-east loops, so I used the sun (through closed eyes) as a direction guide.
Anyways, anyone else ever try paddling with your eyes closed in some decent sized waves?
