We've had problems raising Scrub Island via VHF. I think they rely on handhelds, and the hill blocks the signal. When we were on our way there I couldn't get through to them until we rounded the corner and were staring at the marina.
Probably didn't help that the boat we were on had its VHF antenna attached to the stern rail, rather than at the top of the mast.
