I find the AIS
a great safety
tool, and it makes sailing on a busy body of water
(SF Bay) more enjoyable. If it works as it should.
I had problems with my older Raymarine AIS
and the eS98 and decided sailing is better than trouble shooting so I invested in a new AIS650. To integrate it with my backup navigation
system (OpenCPN) I purchased an Actisense Nema 2000 (with Raymarine
STng adapter) to USB. Thought all was working fine.
Today I heard Vessel Traffic Service
(I typically listen to VHF
14 VTS on the central bay) describe a vessel that I wanted to "vector". I couldn't find it at all, and in fact found NO vessels in the Anchorage 9 area of the Bay. This didn't make sense to me. I checked my OpenCPN
, and there were a number of vessels in Anchorage 9. OpenCPN
showed them, Raymarine did NOT.
I also heard of traffic coming into the Bay from the ocean, so checked that out on the Raymarine MFD and NO traffic in the entrance to the Bay found! OpenCPN, using the exact same data input DID find traffic. I also checked Marine
Traffic, an internet
tool, for the inbound traffic. I never use this for navigation
, but sure enough it showed traffic coming into SF Bay
in the shipping
I want to resolve this asap. I posted the above on the Raymarine forum, but that could take days for my post to be "approved" and a reply received. Thought to try here.
