A weekend adventure (and a lifeboat shout)
Earlier in the month, I had decided that I’d try a jaunt down the coast to see how far I could get on a single ebb tide, and then I’d come back up on the flood; I estimated that it’d basically be a day spent sailing, and that I could reach Wicklow Head. The forecast…

Getting and displaying tide data

The B600s emits some custom sentences to indicate that there are problems (and also turns on a LED labeled “Err”). Some begin with PAMC, others with AIALR. If I remember the NMEA spec correctly, P* are proprietary, so PAMC is Proprietary AMC (Alltek Marine also call themselves AMEC). $PAMC,R,TXT,010,Power anomalies:0.00V*56 $PAMC,R,TXT,200,GPS antenna is not detected*75…
