I believe that if you can get more for same price
go for it, assuming similar quality.
Our radar is mounted on the mast
about 25 feet off the water
. Many times we have identified and tracked large vessels while passagemaking at the edge of the 24 mile radar limit. I like to see them early as possible.
In passagemakeing we actually use the radar to look for storm cells. Many a time we were able to alter course to bypass these cells. In one 3 day occasion sailing from Los testigo to Dominica
we used the radar to locate the squall areas. We would then adjust course towards them and take advantage of the localized wind
shifts to help get us easting. As the winds generally move in a semi circular pattern around the squall we were able to catch a wind
shift that was to the SE or S which let us reach almost due E from the prevailing ENE. We stair stepped our way to dominica
this way. We also got a couple of good fresh water
rinses for the boat this way.
