I carry a 7 kg folding grapnel as a 'Plan B' or kedge; it's used mostly in its' folded state lowered halfway down the main bower anchor warp as an 'angel' to take the shock out of waves and help the main Bruce anchor hold if the wind kicks up.
The theory is that it will also grab a hold on weed covered rocks - i.e. in an emergency situation - where the Bruce won't - but as grapnels rely on a small relatively weak pivot pin I wouldn't stay any longer than necessary !
