Anchor Alarms for Android


So I had a shitty experience one night in San Evaristo. Whether it was the Coromuel or the Elephante winds it does not really matter, the result was the same – a long night.

Yet another substantial, multi-step process… Point of note, Seawind 1160s from the factory have 50 meters (165 feet) of 8mm short link galvanized chain.

It is hard to know the loss from the solar controller or the wire runs so I was excited to see what would…

Solar Panel Installation – Super Charging the Power Systems


Boat in San Diego, new stainless hardware acquired from Marine Exchange, MC4 crimp tool (and connectors) means I’m ready to go! Lug the panels to the top of the solar arch and slide them into position. Jump down to start threading the bolts, using the dingy as a ladder, and find that we have a problem…the outside holes don’t line…
