Eh? You sure? Unless you are so close to the shore that you have your fenders out to protect your topsides, you aren't going to hit anything on SE corner of Cap Ferrat. Never heard of a superyacht clanging anything on that corner. Do you have a reference/link to this possibly uncharted rock?

Not sure if it's on the charts ,This corner has a bad rep
.We Allways take a wide curve in when approaching from the W

This may be completely unrelated to a rock -never got to the bottom of this

Corner does not have a bad rep. There are no uncharted rocks there and I'm pretty sure no superyacht has ever come a cropper there, and you haven't found a link despite no doubt googling it. Reason is, there are no links. If you go close to the shore on SE corner you will scrape your topsides on rocks that you can see before you'll strike your keel on rocks that aren't charted

The two links you posted are nuts. Those two incidents didn't occur on the SE corner of Cap Ferrat and neither involved uncharted rocks.

Let's keep the information on this forum vaguely in tune with reality!

I went round that corner last weekend and cut it pretty close and I survived to tell the tale

 

[Portofino]

There's a wreck bouy there now or was last week -( not to be confused with bigger new yellow bouys ) .

Why would there be a wreck buoy if the boat was towed away?

 

[Portofino]

Theres another unrelated wreck --a fresh one .
Pop back and have a look .

I,ll continue to give that corner a wide birth

Yup, for the record, the geeks got it completely right on Garmin charts. Hurricane's near miss rock shows clearly on Garmin even if you are zoomed out so far that you have 30miles+ of chart across the width of your screen

Funny that you should mention Garmin charts, because I often use them on my notebook for planning and cross-checking (having Navionics on the onboard plotter).
And after reading Hurricane warning, I also had a look at them, with the same result that you are now reporting.
Otoh, I just re-checked Garmin charts for the other spot near Cala'n Bosch, and guess what? There's nothing, regardless of zoom level (see pic)!
That said, fwiw, I only use electronic charts. Life's too short...

Ok, but did you scratch your fender socks against the emerged rocks? If not, you weren't close enough!

 

[MapisM]

I'm confused that none +1 this comment tbh!

Thanks for your appreciation Vas, but you shouldn't be surprised.
These Brit boaters grew up thinking that sea water is brown and dark, so when they come down here, they remain skeptic and still don't trust even what they see with their own eyes.
That's why they prefer to rely on all sort of onboard electronics, rather than just look around!
Bye now, must run for cover...

No, MapisM - you have it entirely wrong.
Yes we (ex) UK boaters are used to dark brown water.
But when we look into the waters around your area, they are so clear that all the rocks look like they are close to the surface.
Thats why we look at our charts.
It isn't that we are used to dark water its that every rock looks like we are going to hit it.
In dark brown water you can't see the rocks - your waters are very different.

I think this video shows why we UK boaters are frightened of your waters.
Video taken from the front of your boat the first time that you showed me round San Pietro

 

[MapisM]

LOL, good point.
Indeed, the coast from CF marina to the NE cape of the island is very shallow, and I only make it at cruising speed because I know I can.
But once you get used to evaluate the depth from above, you can actually be pretty accurate.
Of course, as also Vas said, you must go slowly enough to be able to stop or reverse if necessary.
But aside from not having to trust charts and their accuracy (lack of), you are eventually rewarded by anchoring in some very nice and well sheltered spots...
As an example, this is one which you might remember, but if you look at 1:30 to 1:40 you get an idea of how shallow you can go, just trusting Mk1 eyeball!

I was going to say something similar! I needed the plotter and the echo sounder in CF not to confirm I was in shallow water but to confirm I was in deep water

LOL, the rule of thumb for "eyeball depth watching" is simple: when by looking at the seabed you begin to be in doubt, you can be sure that the depth is more than enough - well above 3m or so.
When it's starting to reach 2m, usually you are not in doubt anymore, and you would swear that by going ahead you'll run aground.
In my previous video (1:30 to 1:40), the bottom was at about 2m or so, but I can assure you that nobody in his right mind would have anchored there just by judging the depth from above.
TBH, I only did it because I had already snorkeled in that area before...

Great video clip MapisM. You are obviously familiar with those waters. Looking at underside of vessel about 1m34s into clip, one question, would there be a risk she might hit the bottom if struck by the wake of a vessel passing 1/4 mile or so away?

(i.e. causing your vessel to bounce up and down, or does the shallow water absorb/dissipate wake from other vessels)

 

[MapisM]

Good point, but believe it or not there's never less than a couple of meters of clearance in that video, and I mean under the boat keel, which is 1.5 m under the surface.
Of course, a 2m wave in principle is nothing so exceptional, but not in that area, which is very sheltered.
And boats big enough to create such massive wake stay well clear of those shallow waters...

PS: ops, sorry, I just realised that you were talking of the part while anchored, not while cruising.
Yep, indeed in that spot there was much less than 2m under the keel, but I wasn't too worried anyway, because - yet again - in that spot I've never seen any vessel capable of making significant wakes passing close to the coast.
Besides, the "real" bottom is actually a bit lower than it appears in the video, because the posidonia seagrass is at least one foot high, if not more...

Thanks. Ok the optics angle deceive, at 1m34 it almost looked as if there is only 0.5m under the keel but obviously 1.5m is plenty to cope with passing wake. Fab video clip, really enjoyed it.

 

[MapisM]

LOL, no optics deceiving, you were actually correct - see my late update to the previous post!

 

[petem]

Ok, but did you scratch your fender socks against the emerged rocks? If not, you weren't close enough!

He better not have scratched those fender socks!

But thats the point. If your boat touches the seabed it is the keel that touches first and your props will probably still be OK. On the other hand, with most planing boats, the props are the lowest point and even a very slight contact with the seabed will damage the prop blades or worse. In other words you can risk it and most of the rest of us cannot

Well Pete your fender socks will undergo their sternest test yet during the coming months. Our berth in Antibes is much tighter than the one we had in CF and the fenders are constantly squashed against the boats on either side. If they can survive this test they can survive anything
