LWL...right. Either way...but i'd rather wear a tether than a wetsuit. I fell in the water up in Maine in the summer a few years back just while at the dock and it took every ounce of my strength just to get back in my dinghy. Gave me new respect for the sapping power of cold water!
Funny..but the kids up there go swimming in the same temp water. Don't know how they do it!
