We alternate cruising on a
power boat and
sail boat. Wanting to get XM Sirius
weather, we found we’d need two subscriptions and two antennas to have on both
boats or have to put more effort into rewiring and moving one
antenna back and forth between
boats. So we figured we’d make a portable system to serve as the
weather station and back up plotter. We settled on a
SIMRAD Go7xsr and WM3
antenna as the least expensive option, mounted to a little box we could
plug into a 12v outlet.
Here’s our experience:
1.
SIMRAD Go7, with the CMap chart chip doesn’t inspire
navigation confidence in our area when the roads show up plotting over the
water. Simard confirmed that's what they got too. (glad to have
navionics on an iPad)
2. XM weather was useful for sailing with
wind and wave direction, but the
marine zone forecasts were unavailable most of the times we checked, so we were back to listening to NOAA NWS
marine broadcasts on our
VHF. Had really hoped that we would be able to get to the text forecasts easily and often.
3. Weather
radar is OK, though not a lot of experience with this function yet, but the rain areas are pretty pixilated and not as precise as an
iPhone app like
Radar Pro.
4. Sirius weather reboots every few minutes with a distracting graphic default that has to clear-up before getting to the update.
All in all, we will keep the subscription for a few months for the times we are cruising out of cell range. All in all about $1,400 for a marginally satisfactory result. Considering the cost, hassle and less than expected performance, perhaps a sat-phone to get data from weather underground, NWS, and Radar Pro might have been a better option.
