A couple of comments on radar: a mast-mounted radar will “see” vessels further away, including over the horizon compared to deck-level. But as Chuck mentioned, it will not see things in the water closer to the boat, as there’s about a 12.5° vertical beam width above/below horizontal on most marine radars; so as a target gets within several dozen yards of the radar, it’ll be too low to be picked up. Using a stern pole can help with this close-in imaging of targets; but you lose the distant ability of having the dome up high.
There is also a danger with stern pole mounting of having the radar beam hit deck crew; stand too close to a high-power radar beam, and you can develop some nasty medical issues like vision loss. This is an issue I have with power boaters who mount the dome right on their hard top (usually a large open array…), then come into the dock on a clear sunny day with the radar merrily turning away. The beam is pretty much at head-height for anyone standing on the dock, and it’s pretty easy to get a nice face full of microwave radiation at close range. Chuck — as far as NME0183 vs NMEA2000 on the Raymarine a, c, e, and eS Series MFDs, ALL of them support NMEA2000. See page 51 of the a-c-e Installation Manual. The smallest versions of the a and c Series DO NOT have NMEA0183 connections on them at all. — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( > On Dec 29, 2015, at 1:51 PM, Chuck Gilchrest via CnC-List > <[email protected]> wrote: > > Mike, > My experience with mast mounted radar is not favorable.
