Pedro Almeida over at the Kayak Building Bulletin Board has come up with a new and interesting version of a rope carrying handle. He uses a series of knots to bring together four separate cords to form a carrying handle for what looks like a comfortable grip. For photos of Pedro's kayak and deck rigging including the carrying handles, visit his Flickr site here.
Pedro has very graciously written a set of illustrated instructions and has provided that to the boat-building community. You can find his instructions here.
