Beware the tides of March!

Alex with his pinhole camera contraption. It worked! Syzygy, aurora, eclipse, meteors and more! The Ides of March has a bad reputation but it passed unnoticed this year; and this month we also had a Friday the 13th, which some people are rather superstitious about. But that came and went without much ado as well. We got lucky with weather overall as St. Patrick's Day was dry and not too cold. The parades, especially in Newport, were great fun, and there were only two ankle injuries during the ritual sunrise climb of Croagh Patrick. No, I did not climb. Done it once. The highest tides in the spring are always around St. Patrick's, Day and this year they were a couple of days later. We live by the sea so we are used to tidal variation. I suppose that's an understatement in that we live on a one lane road by the sea which is under water during the big spring tides for an hour either side of the high tide mark.

Aleria's Jaunt to Scotland: 15 July 2013, The Gulf of Corryvreckan & Pig Bay, Jura, Scotland

The Race, whirlpools, swell and ticks…dangers all around. Gulf of Corryvreckan between Scarba and Jura Water boiling and whirlpools at slack water Aleria was among the first group of five boats to pass through the Corryvreckan and, even at slack water, the water was still boiling all around us as we passed through under power at almost 10 knots. Our speed through the water was only 5.8 knots as we raced over a 224 foot deep chasm that would soon shallow out abruptly. We were being set quite substantially. We anchored in hard sand and weed in gorgeous Pig Bay (Bagh Gleann nam Much) just on the inside of the top of Jura with the Race's waters rushing past the opening to the Bay while inside it was calm and secure.  The Race extends out quite a distance, which is called an overfall here in Scotland. Luckily, there wasn't much wind, only about 10 knots, because when wind opposes tide, it can get very nasty, with standing waves and square chop intertwined.  9.

Aleria's Jaunt to Scotland: 9 July 2013 Islay, Scotland

Land ho, Scotland! At least I think I see it.  Sailing in light breeze nearing Malin Head We awoke at 7 am to a beautiful sunny morning.   Soon we were underway but planned to take our time and use this wide open Bay in Donegal with no swell or wind to calibrate the autopilot. Without it we had been taking turns hand steering all day.  To calibrate Otto, you have to give the autopilot control and walk it through a series of manoeuvres and turns so it learns your boat, which can be quite unnerving. So we gave the program control and sat back watching.  Just as a little speed boat came charging out of the harbour toward us waving hello, our boat veered sharp left.  Aaarrgghh!!!  We were about to bash into them, when they bore away swearing at the rude sailors thinking we were aggressive nuts! But soon the autopilot informed us that it had learned enough and passed the test.  Cool!  Disaster averted, and, more important, calibration complete.  One more thing expertly installed
