   it would be line of sight, so probably crap in the big stuff. (just googled, vhf ok with good line of sight, uhf better when their are obstructions).

	Actually the shorter the wavelength the worse the performance if obstructed so UHF is less effective than VHF but a couple of waves would be unlikely to reduce the range by very much. Line of sight is the official limit but the land station aerials are several metres off the ground giving an effective range of 50 miles+. At sea level in Holyhead Bay I can receive transmissions from both Liverpool and Belfast Coatsguard radio, neither of which have LoS. I would not expect to be able to transmit to them with my handheld but reaching Holyhead Coastguard radio from my sailing area is no problem. Also all vessels/VHF users are required to keep a watch on Channel 16 at all times.

	Should have said in earlier post, no need to use leash when racing, not such an issue when you have safety boat cover, when cruising you don't generally speaking throw yourself from side to side, therefore less likely to get tangled up.
