For a dozen years, I had a cottage on a small fishing lake in NE Indiana. It did not allow skiing or jet skis so it was very quiet and peaceful. I only wore a small speedo around the cottage so the neighbors were used to seeing me with little clothing. I would take my kayak out on the lake and just pull my speedo to my ankles. It was such a great feeling to just glide around the lake nude with no one being able to tell the difference. I could do the same with my pontoon. I spent many days on the water nude with a good book.
There are a number of lakes and rivers close to me and have thought about this. So far, my kayaking has been with others (textiles). Most of the lakes are pretty active. Many secluded places on the local rivers which are mostly surrounded by woods and grasslands. I have a basic sit in kayak, so not even sure if it would be that noticeable unless someone was right next to me.
I've gone kayaking nude on two trips, one in Lake Muskoka, north of Toronto and the second time on a lake in Maine. In both cases, I climbed into the kayak and took off my swim suit and stashed it in the container on the top of kayak. It's the only way to kayak, so much fun
Always nice. It would take a keen eye to see that I'm only wearing my hat. I usually manage to give other craft a wide berth which suits them as they generally have a line in the water. Getting the suit back on before landing can be tricky, especially since I want to delay that moment as long as I dare!
