I have both a 28' (for mostly local Chesapeake Bay
inland sailing) where I designed/ installed a 3" dis x 7' radar mast/ and versatile custom mounting plate. For me/ my normal sailing area where 5-10 mile radar view of big ships going up and down Bay and 3-4 mile view of smaller vessels/ Nav markers was perfectly ok. Also since I'm a ham operator I designed the radar antenna
mounting plate with two extra lobes on port and starboard sides to allow easy mounting of standard 1" VHF antenna
screw mounts. One of these I use with an extension for the GPS
antenna (I have an older chart plotter with external antenna). The other side I have a 2m/ 440 MHz vertical for ham use (and could use as emergency
marina VHF). I think a properly design/ installed radar mast looks very good on any boat!
I have a split back stay plus I converted it to insulated backstay so didn't want to mount radar there. Plus, I always had concern about swinging backstay radar eventually breaking there power/ data wires (when you most need them!)
Long distance cruising boat is a ketch
and different from your choice. I put steps on mizzen and have radar, ham vhf
, uhf, wifi
, tv antennas plus radar and spare vhf marina and spare tricolor/ strobe at top. All accessible because of steps.
If your are planing a lot of far offshore
sailing where long periods of limited visibility are encountered (rain, storms, nights), I think it I would lean for height/ range of main mast mount. Despite the 'little boat, big ocean' theory... nearly everyone of our nine Chesapeake - Caribbean
non-stop trips has had a close encounter with a BIG ship that would have been way too close if we hadn't seen, plotted, watched carefully and eventually had to changed course. (Not that I expected/ wanted them to change course but interesting that there was no response on ch 16 from any of them!).
Depending on your boat use, having a lifting arm/ installed on an aft radar mast is very handy for dink outboard
retrieval. Also MUCH easier installation
if you are doing it yourself.
Good luck with your decision.
