Cruise ship hits bridge?

That sail boat (41m Fitzroy S/Y Inmocean) had a draft problem not air draft problem, the tide was very low and it ran aground

It took around an hour to clear her.

Cheers,

I might had mistaken that particular story for an air draft issue, when it was the other draft issue to be known. However plenty of vessels have hit the underneath of that 17st bridge. I am sure you can still see plenty of battle scares telling all kinds of stories of hurt underneath that bridge.

I was not arguing your point at all, just adding the information you might have missed, and one needs just to do small search on you tube for "boat bridge" and see the results. This thing is very common and should be taken into consideration and given the right thought and arrangement.

How do truckers know or learn there height for bridge clearances?
Not just for the cab, but I am thinking every load could be different, with different trailers or cargo trailing along to be delivered. Some of them are even pulling yachts.

I check air draft with a tape measure.

Air Draft on a cruise ship can change by several feet depending on the weight of the vessel at the time. How much fuel, water, passangers, crew, etc.........

Hello Friends, Personally I m surprised to find you guys great conversation...

Not to mention salinity can have an effect on air draft as well. Which is why when I measure the air draft with a tape measure I also make a reference note of the measured distance from the bulwark to the surface level of the fluid I am floating in.

Yes, every now and then these guys do have something fairly intellectually stimulating to share
They have taught me a lot

Who says that the height of the bridge published was correct, this is China afterall.
In this photo we were supposedly having 5 meter clearance...

Most yachts would do as you described, which is what I do as well, if there is any doubt use a spotter and approach with caution and control.

C4ENG,

When was the last time you went under the 17th Street bridge, Firstly it is an opening bridge, refered to as either a draw bridge or a bascule bridge. 55 foot clearance when the spans are down.

There is no evidence "of plenty of yachts" hitting the new bridge and leaving scars, maybe you are thinking of the old bridge which most certainly had plenty of not just scars but heavy hits on each side and on the underside.

The bridge opens on the hour & 1/2 hour or on demand for commercial traffic.

Besides being a dull concrete color the bridge is one big mess (IMO) and I find it puzzling why the city do not do as they did with the old bridge and have it painted or at least clean this one up. A poor design seems to allow everything to drain off the road way onto the concrete.

Good eye Pascal. Good bye Latina431.

I will look again under that 17 bridge to see if I do see evidence. I am sure there are paint marks from sail boat mask and yacht antenna's scrapping. Battle scares might had been an overstatement. I was thinking more about Simpson Bay bridge SXM, that bridge has serious battle scares all over and under her.

What happen to Latina? I was just getting to know her. You mean she wasn't what I thought? I wonder how often that happens?

There weren't any a couple of hours ago ...

Bridges

Next Tuesday June 1/12 I will be going up the Welland Canal with a Volvo Ocean 70' Puma Racing sail boat and she has a 105' mast. We will be going under the Garden City Skyway which has a 110' air draft.
Name of sailboat is Il Mostro (Italian for Monster)
She will be in the Mackinac race this year.
I will be onboard the owners 85' Pacific Mariner and will get pictures going under the bridge.
