Yep, grp 34. The cable with clamps would be used only in hi amp jumpstart mode. I would not leave it on while under way. I would be using the cigarette cable most of the time.
The cigarette cable also works fine for jumpstarting--just plug it in and let elec system equalize for about an hour before cranking. Actually the shortie clamps came from a dead charge pak I had lying around... I had an extra plug and the cable is a nice 6 guage with strong jaws... Also works great as a "portable" battery bank for the elec reel for use on someone else's boat...
