Rough Translation:

"Brenta 60 Minnic sailed ÅF Offshore Race earlier in July. During the holiday sailing in the Stockholm archipelago seems to have gone on a basis of Möja Västerfjärd . The stone stood at 2.2 meters and the boat stand 3.3 .

Christopher Carlbom , who was on location , type of no- crew on Facebook.60 -foot sailboat with five people on board , including 2 teenagers , ran aground on which the keel was broken off and overturned . We picked up a person from the water and rescued by another boat to get on board the other . That was the case very well, only minor injuries and a very traumatized guy. But after a few hours at the rescue station with drink and debriefing , we can now check them in the inn .

The important thing is that it went well for everyone on board. Shit happens , and everyone can go to the foundation. It is perhaps not optimal to do it with this type of boat, but I have difficulty seeing how to build boats that can withstand everything it can expose them to ?

Heard the way to a much more regular boat had lost its bulb at Bohus race . There came , however, in the country without the boat tipped ...

The boat was previously named UCA and so it can look like when a Brenta 60 is not upside- down:" - www.blur.se

Keel looks intact, but where's the rest of the bulb?

Edit... Dang, nice looking boat too. Sorry y'all.

This eerie ghost ship is the Mar Sem Fim, a Brazilian yacht that was shipwrecked near Ardley Cove in Antarctica. A Brazilian crew had taken it to film a documentary, but strong winds and stormy seas forced the crew to abandon ship. The water that washed over the ship froze, cracked its hull and sunk the yacht, but it has since been salvaged.

[SIZE=10.5pt]Hi everybody,[/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]this is the former Luca Brenta Yacht Design partner, Lorenzo Argento, responsible for the design work on the B60. So far all we know is what we can see from the pictures as we did not speak with the people on board and also the builder does not know anything yet. Nevertheless, I wanted to come back to your community as you have reported the news.[/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]Keel design for any yacht designer is the most delicate structural element and factor of safety are very large, particularly on a fast "cruising" vessel like the B60. Grounding load cases, in particular, are considered as one of the various load cases.[/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]The debate is always between how strong the boat structure shall be versus the keel+bulb structure. Meaning that if you hit a rock, either the boat (keel floors, keel panels etc) collapse under the impact load to a point where the boat may eventually sink...or alternative the keel breaks...leaving the boat without keel and therefore she will ultimately capsize. This in general terms the worst case scenarios.[/SIZE]

[SIZE=10.5pt]I witnessed my self a 77ft sloop hitting the Lavezzi rock at speed and sinking soon after. The good thing was that as the boat structure broke (causing her to sink) there was a lot less deceleration of the boat as a whole, which is ultimately did not leave anybody hurt. Try to imagine to steering a boat that goes from 10 knots to 0 in less than a second....you may save the boat, but this could cause a lot of damage to the crew. Is like crashing with a car….something has to take the load, minimizing the impact on the human body. In the other scenario, the deceleration is taken by the “soft” lead bulb….which ultimately transmit the load to the keel and than to the boat. The important thing is to reduce at maximum the deceleration……which may mean sinking the boat, but it also means saving lives. [/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]From what it is shown from the pics, the boat clearly lost her bulb. The early report says that they hit a 2.2 mt rock with a 3.3 mt deep keel. My only hypothesis at this point is that the way they hit the rock has phisically (think of a rock with a step....or something similar) snatched off the bulb. At this moment I can not think of anything else. Further investigation may prove if this is the case or not. [/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]Ultimately, the most important thing is that nobody got hurt and they are all safe at home.[/SIZE]

[SIZE=10.5pt]Secondly we may learn a further lesson from this case, but for sure I would like to keep it very public and let people know what has happened as it did not happen under “standard” circumstances but evidently as a result of a human error (think of the Volvo Vests “flying” on the rock at 19 knots).[/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]I will keep you posted, as soon as I will learn more.[/SIZE]

[SIZE=10.5pt] [/SIZE]

[SIZE=10.5pt]Regards[/SIZE]

Thank you Lorenzo for weighing in.

Clearly, rule number (1) is, don't go running aground, especially at speed.

this is a nasty stone at 2.2 m in the middle of a very white area on the chart. Thus nothing that de-accelerates until just the bulb (and probably only the bulb) hit the stone while the rest of the boat continues.

We all run aground up here, it is inevitable. Most often softer groundings as most boats draft is more limited, mostly 2 m or less. Stockholm archipelago is not fully chartered, and most of those areas that are said to be were measured ~100 years ago. Also commercial ships, even with pilots, run aground now and then.

Now and then there are cases when parts of the keel, or the complete keel, is broken away. There are some fun stories about Bavarias where the crew did not notice the lack of keel ....

As of yesterday the boat was still said to be drifting, no one picking it up. Is it a total loss just because of turtling?

can anyone grab it at this point and own it by bringing it to port?

Looks tricky to learn sail around archipelagos.

I understand why Folkan is such a good boat for those places.

Not in National waters.
depends on nation, doesn't it?

An abandon boat, just drifting - that is clearly possible to claim. At least in Scandinavian waters.

But not so easy, mast is on, probably stuck in the mud somewhere. Sails could be there as well. the boat cannot be towed into any harbour in that way it has to be turned right first. For this something substantial is needed. Preferably also some divers to check everything before and during turning. So this will be expensive.

At the same time some "experts" has claimed the boat to be total loss. If so, it would be difficult to regain the expenses for saving the boat.

(I have my doubts, but value has certainly dropped)

We'll see

Rough day for crew, glad all are safe. I do from time to time roll a dinghy to inspect the bottom during a race just to be sure we're clear of weeds ;)

Weed check gone wrong?
