  • A Sailing Holiday – Dun Laoghaire to Arklow

    A Sailing Holiday – Dun Laoghaire to Arklow

    The planned holiday this year was for K and I to take Blue Opal to Ireland’s south coast. Initial passage planning had us going Dun Laoghaire, Greystones, Arklow, Kilmore Quay, and day-hopping west along the coast. After asking around about cruising the coast, the plan changed to Greystones, Arklow, Kilmore Quay, and then push for […]

  • Making a cockpit table

    Making a cockpit table

    A tale of measure twice, if not thrice, yet also cut thrice… Blue Opal does not have a cockpit table, but she does have a Cobra compass binnacle setup, and it’s more than sturdy enough to play host to a cockpit table. SVB and the like all have teak tables costing several hundred Euro, so […]

    In a previous post, I noted how the AIS sentences had caused me to think that the VSWR alarm was being triggered, but in fact they were inactive alarms. However, I decided to get a baseline SWR reading, and a fellow club member was able to meet me on board today to conduct some tests. […]

  • AIS alarm sentences redux

    AIS alarm sentences redux

    Back in 2020, I posted about the alarm sentences for the B600s AIS transceiver by Alltek Marine. While on the boat this weekend, I was monitoring the NMEA sentences while testing some new software, and I noticed that the sentences were still showing up, and the AMEC app on the tablet was also saying “Error”.
