Did you ever have the feeling that seakaying is fine but that carrying the kayaks afterwards is a torment?
Of course toggles have been developed to bring comfort in carrying, but after paddling for a day or after having played in heavy surf the muscles of my hands and forearms are probably too tired to like gripping a toggle for carrying a kayak. So I have often to rest when carrying two kayaks or change hands when carrying one.
Once, while roaming the beach, I found a very strong band. I picked it up (all people from fishermans-villages like finding things ; in Dutch = "jutten") because I got the idea that it might be useful for carrying kayaks. First I experimeted with it, carrying from the shoulders, but I found this too clumsy to be practical.
Next thing I invented was wrapping the band around the wrist, like you do with a plastic shoppingbag when it cuts your fingers, just to take the strain away from my fingers.
That works, so I bougth 2 metal clips to connect to the toggle-ropes and sewn an endless ring from the band. So just put your hand in the band and click on. That´s all; it´s so simple!
