Sailing the Adriatic - from Tri sestrice to Olib

And we're back to under water photos again :-)

The evening of Monday, 11th of August, was really pretty. We saw rabbits on the island and a big owl was flying by, probably hoping to get a rabbit.  We had a very peaceful and calm night at Tri sestrice.

In the morning, after a swim and a breakfast, we had to sail off.

Our plan was to sail as far North as we could, and make a stop for snorkelling at couple of small islands South of Silba. They are a bit away from any inhabited islands, so I hoped there would not be many tourists there and the snorkelling would be good. But even before we reached them, we saw they were quite steep, and indeed the chart showed that the water around them was rather deep and there was no good anchorage. We sailed closer, took a close look and decided to sail on to Olib.

We anchored in a wide sandy bay on West side of Olib. I wasn't expecting to find much in the water, but was pleasantly surprised. It had the same feeling as Marie Galante (you can see it here and here ) in Caribbean - from the outside I could see very clear water, plenty of sea cucumbers, but not much more. But then under the water it was totally beautiful.

Almost right under our boat was this car tire, full of empty shells. I knew that the octopus couldn't be far away. 

And as I looked closer, I found her, squeezed between the tire and the shells. If she keeps eating so many shells, soon there will not be enough space for her in the tire.

The shells were obviously there for longer time, a Trumpet anemone (Marmornata morska vetrnica) was growing among them.

There were also some Tunicates near, the White sea-squirts (Bradavičasti kozolnjaki), in company of Yellow sponges (Spužve žveplenjače).

Here is the Hermit crab (Raki samotarji) section - look how pretty blue eyes they have. And most of them carry the Parasitic anemone (Progasto stražno vetrnico) on their house...

... and this one lives in Murex shell (v Čokatem voleku).

These are the eggs of one of the Nudibranches (Golega polža) - it looks like a delicate lace.

This was one of my best discoveries - the Long-snouted seahorse (Dolgonosi morski konjiček). This was the second one that I saw in nature in my life.

Tried to get better photo from different perspective, but the poor guy tried to disappear into the ground, he was clearly not happy with me swimming so close, so I took another photo, said thank you  and left him alone.

And another pretty blue eyed Hermit crab.

I found a big octopus, don't know if this was the one from the tire.

Next morning was calm and sunny, water was so clear, I could see the octopus castle from the boat. And of course I took some photos.

After the breakfast I went snorkelling again, I didn't want to miss the opportunity to snorkel in such a great place. I found another type of tunicate, it is Rožnati plaščar.

When I was taking the photo of this Potato sponge (Ledvičaste spužve), I noticed the anemone.

It is probably the Daisy anemone (Sončna vetrnica), it was too hidden beneath the rock to get better photo and be sure.

As I was swimming around, a big group of fish started to follow me. Maybe they thought I'm on the hunt for food and they could get some crumbs.

I think this is another Tunicate, it could be Nagubani kozolnjak. It is hard to tell though, because it is so overgrown with algae.

This is one of the Tube worms, the Twin fan worm (Dvoperjaničar).

This is one of my favourite fish, the Redmouth Goby (Rdečeusti glavač).

I finally found a Nudibranch - this one is called Platydoris argo (Ploščati perjaničar). After this one I found three more of the same kind, I learned what to look for.

This is a Murex shell (Čokati volek), alive and well. Not just a shell inhabited by Hermit crab.

I have no clue, what this is. Maybe some kind of eggs. They were tied around the tube of the Mediterranean tube worm (Spalancanijevega cevkarja).

When I was swimming back towards the boat, I saw this little beauty swimming in the water. I have to take a lot of photos to get a couple of decent ones, since both of us were swimming up and down in the water. It is probably a Tubellaria (Bradavičasti vrtinčar).

Despite the beautiful anchorage, clear water and great snorkelling, we had to move on. I was sorry, it was such a pretty place and great weather, the summer was finally back. But we had to be on Krk the next day, and according to weather forecast the bad weather was coming from the South in the night, so we would not be able to stay in this anchorage anyway.

Shortly after the noon we sailed off,  towards North again.

Fixing damaged cleats

Hi, this is the captain. 

This means you can expect a technical post and no underwater pictures. 

Not even a picture of me diving into murky water to retrieve a chisel I dropped overboard.

We came to the boat two weeks ago and found out that the storm caused some damage on the boat. The cleats survived 10 years of use and abuse with no major problems, but now they were twisted and the teak rail was split. 

Stern port cleat sustained minor damage

Teak rail was cracked

Bow port cleat was in worse condition

Bent

Teak rail was fully split

In reality it looked worse than on this picture

12mm bolts were bent, but fiberglass base (hull and deck) was luckily intact

Removing 40 cm section of teak

Removing original black sealant was not easy. After 10 years it was still very flexible. 

Aluminum base was installed instead of broken teak railing. This solution is a lot better. Access from anchor locker is relatively easy. Being short is sometimes an advantage. That is me inside the locker.

Work in progress: Teak is sanded and hard edges removed.

Finished cleat after repair.

When I work on a boat I usually use a lot of tools if I have them.

After we finished bow cleat we started working with the stern one.

Access to stern cleat base from below is a lot more restricted then for the bow cleats. 

This is how cleat looked before it was bent

This is how cleat looked before it was bent (from above)

Sanding off the edges of the teak railing

At stern cleat the fiberglass base was damaged and we repaired it with epoxy (sorry, no pictures).  

I wish my arm was longer. A loooooooooooooot loooooooooonger

Hmm. How on earth can I reach that far and position a nut on the bolt ?

After picture. Stern port side.

How could all this happen?

The mooring field looks similar to the one on this picture:

Each boat is tied with four lines and chain to large heavy chains, which are screwed to the bottom.
Heron was moored at low tide. 
It looked she was tied too tight and when the tide was high the lines were probably already stretched.
Then the storm came. Mooring field is relatively well protected from NE - from strong Bora winds. Also the bow of Heron is facing into prevailing strong winds. But there are sometimes short leaving storms with N wind. Fetch is not very long from N (a bit over half of a mile) and this storms are usually only lasting for an hour or so, so waves are normally not a problem.

But if you add all factors together you get this:
- Lines fixed at low tide were too short,
- Lines are oversize to protect them from chafe , so stretch was small
- High tide was amplified by strong N wind during the storm
- Wave action was violent - waves were probably short but steep
- Bow is facing NE, so wind from N or even NW hit Heron abeam to her port side
- Sails (furling genoa and main in the lazy bag) increased windage
- Solar panels, dinghy, spray-hood and bimini all increased windage even more

Lessions learned:
1) Do not underestimate the power of sea even if you only leave the boat for a week during summer in protected bay
2) Observe tide tables even with tidial range less then one m.
3)  Leave some slack in the lines to allow boat movement and rocking in the storm
4) Reduce windage if practical
5) If something held for 10 years it can still break.


Let me say at the end that original design of this Beneteau cleats was not the best. Beneteau changed the design a year later  - so they learned, but a year too late for our boat
Original design: A cleat is fixed with two 12mm bolts and goes through teak railing, through deck& hull joint, through backing plate and is fixed by nuts.
Where the bolt goes through teak railing there is a round piece of aluminum (3cm in diameter and 3cm high). That round piece is sitting exactly where deck ends, so it does not have a lot of good support.
And 3 cm diameter is not a lot to start with.
A lot of force is therefore transfered to bolts as bending force.
New design: I obtained original Beneteau aluminum parts for replacement
Instead of teak railing with 3cm hole in it there is a solid aluminum plate which is 40 cm long and as wide as the railing base (I did not measure, but it is about 8 or 9 cm). The inner side of it sits well on the deck and outer edge sits well on the hull. It is 2cm thinner than original design reducing leverage on the bolts and it is a lot stronger, as a solid piece of aluminum sits on 9cm wide base comparing to 3cm base partially overhanging hull/deck joint inside hollow teak plank.
Conclusion: It was not only a repair, this was a boat improvement as well. We will do starboard cleats in the near future.
