Microburst

So, I had this interesting phenomenon happen August 2013 and when I spoke about it people thought I was joking.So I put it away in the back of my mind and forgot about it.Well that was until I heard an interview on 59 North Podcast by Andy Schell with his interview with Yan Miles, Yan spoke of a Microburst and it got me thinking if thats what I had experienced.

So I was out for a nice sail

Sailing between Dun Laoghaire and around Lambay Island en rout back to Dun Laoghaire.

Wind was steady around 20kts so I had one reef in (my reef's take out 2Mtrs of main each).

Then the an interesting pattern came into play in the sky!

The sky was bright round the weather system but really nasty under it.

I saw what looked like small rain storms, and oh yes they were headed my way!!!

Still bright and maybe a small look of apprehension on my face !!

Maybe 3-4 mins before it hit me.

I rolled up 2/3rds of the jib and held onto the jib sheet.

As the squall hit the wind changed direction, vilantly by around 60 degrees which caused me to tack, fortunately I was holding the jib sheet so I just let it go.

Just look at the windspeed!

Up it goes

Still going up

Not sure the instrument goes any higher.

And back down again. Thank the lord.

A short clip.

So what happened.

Now I think it may have been a Microburst,
Wikipedia definition

This is a clip from someone who had replied to the podcast.
Tucson Wet Microburst | August 8th, 2015

From my side:

• I learned to prepare for squalls. I could see it for miles and it lasted only 3-4 mins in total.
• To roll up the jib prior to it hitting as jib as the whole of the sacrificial strip sticking was blown out and needed re stitching.
• One of the wind speed cups broke off during the squall.
• The VHF whip disappeared.

I think holding the jib sheet saved me from a sure knock down, but rolling the jib would have saved the jib!!

After all that there was only just enough wind to sail home!!!!

We live and learn

Great Irish June Bank Holiday 2014

Evening Sun - Howth

It started out last week with great hopes of a high drifting up from the Azores to sit over the British Isles for the week.
Hopes continued to rise until Thursday when the great low decided to haunt our weekend with forecasts of torrential rains and a nasty low infested week to come.
So plans rescheduled we had a great Saturday sail North to Howth mooring off the breakwater in glassy seas and calm skys.

The windlass had its first test and performed to perfection.
The dimmer fitted to the new fuse panel came into its own and was needed for night time.
The aroma coming from the restaurants from Howth were amazing.

But the setting sun was beautiful.

New Switch Panel

The fuse panel of most older yachts seems to be a bit of a bug bear.

This is my original fuse panel. 12 switches and fuses.

During the last few years I have been running new "tinned" AWG 12 cable round Nimrod with an eye on getting a new panel.

You add a stereo / chargers / GPS / cockpit lighting / fridge..... and on and on and on.....

As you keep doing this you find that you have multiple electrical items wired to the same switch and that 5AMP fuse is now 15 or 20AMPS. I ended up with more and more cables coming to a really small panel.

The tipping point came when I when to install the new windlass (details of which can be found at (windlass-replacement-2013-2014).

You can see the new power cables for the windlass (LHS).

So where do you find a new switch panel.

What you end up with is more of the 6 way fuse panels or custom made panels.

Or you do it yourself.....

I fabricated a wooden frame for the panel.

Wood, Oak from my wives uncle's kitchen he was replacing.

Purchased my toggle switches / LED's and fuse holders (The fuse holders are mounted on the rear of the panel and are standard car style spade fuses rather than glass round fuses costing $$$ each.

With the help from my friends at a local print shop we mapped out a graphic using all the available space on the panel.

Several careful hours of drilling and soldering later and we have a brand new custom switch panel designed specifically for my needs.

New switch panel up and running.

The graphic at the bottom with the holes in will have red/green/white LED's depicting the Nav lights in use.

This pic shows the brightness control for the LED's and the Windlass thermal fuse.

The brigtness of the LED's can be tuned down or off as required.

Finally, Hector is installed.

Opening Remarks

This is going to be the blog of Nimrod of Beaulieu, an original Dufour 35 sloop built in 1972 and loving restored and sailed by her current owner.

What did you do last weekend !

Please click on any picture to enlarge

So you drive to the marina (Dun Laoghaire) and the weather looks fine for a nice long yacht!

Wind picks up but not as forecast. every forecast tells me the wind is from the North and I am getting a Southerly 10-12 kts.

Local weather I hear you say. Well so local it spread across the entire Irish Sea from IRL to Wales!

So some time later (10 hrs) arriving just as darkness has descended I arrived into Llandwynn Island, situated near the southern entrance to the Menai Strait.

Now entering an anchorage after dark is tricky but if you have been there some many times its etched in to your brain, you should be ok!

Anchor down, hot shower a bit of grub and a well-earned beer later a great nights sleep was had.

And this is what awakens you if your lucky!

Just look at that sky

When you pop ashore the picture is just as good

Then your friends arrive from Conway

 

And obviously on a night like this that has to be a BBQ while we watch the sun go down like perfection.

Now off for home.

Forecast if for light winds from the North (again) with a clear warm day for the Irish Sea.

MMMMMM, not at 06:30 it wasn't!.

Damp and slightly foggy I can tell you.

But still. Quiet and light winds prevailed, and yes from the North.

As I cleared Anglesey the view around me and ahead was surprisingly different to that which I was leaving

 

Isn't there a rule about right of way? This chap made me alter corse. Not an issue on a clear settled day but makes you wonder...

Had a great sail home, wind again 10-12 kts from the North most of the way which helped clock off those miles.

Finally Dun Laoghaire and Dalkey in sight!

Well the forecast did say that a front would be passing over Ireland during the evening!

And that is a front if I have ever seen one!

Arriving into Dun Laoghaire. Just look at the front approaching.
