Need to install a new VHF antenna to a sailboat.

Put a 1/2 wave antenna as high as you can get it. 2000 meters is great!
but the top of the tallest mast will do just fine.

When you're screaming for help in a sinking boat, you can never have an
antenna that's too high! The altitude of the mast antenna more than makes
up for the length of the cabling losses. With a 25W Icom and 1/2
wavelength Metz whip at 55 ft on the other end of 30 meters of RG-58/U
coax, Lionheart can call the US Coast Guard station way out of sight of
land.
