Bene 361
Has anyone actually measured the air draft?
I mean put a tape to it.
I know what the Internet says but when your talking cm to get under a bridge I rather know jto the mm ( now we left the EU should I said to the ins ? ) .
15.8 bridge manual says 15.1 add to that VHF Aries.
Click click click comes to mind .
Not sure my heart would take it .

I come up with three different measurements.

And you don't know the accuracy of the bridge clearance published which in any case would need to be adjusted for actual water level.

 

[sailaboutvic]

What in our Favour is the water levels are lower then normal here in the Netherlands.
The bridge hight is set to NAP .
We been throught this bridge a few times over the last few weeks , each time getting them to open it for us ,
( major road) but there going to be some work in the coming weeks where the bridge possibly won't be opening .
I been known to pust my luck with tides but a concrete bridge Mmmmm .

Too bloody bloody hot .
Tho it's looking like the only option as on bene site every one given different measurements

 

[dunedin]

1) Pull rope up on a halyard and tie knot at deck level
2) Walk a fair distance away and take telephoto camera shoto of the masthead.
3) When lowered, measure rope length
4) Measure water to deck level
5). Estimate extra height from photo
6). Add rope, hull and mast measurements.

Thank , we have already done at that good estimate unless your talking the different of a few CM , which we are.
Which is why I'm asking if anyone has put a tape to one.

Our rought measurements some weeks back was 15.2, that's to the top pull which probably a CM below the mast cap then there the VHF,
Now can you you see how important ever mm is ,

Before anyone suggests, going up the mast while approaching the bridge no thnks ?

I thought Beneteaus can bend a few cm's under a bridge easily

Now wouldnt that be good . Is the fixed ?

Is the boat ever moored alongside in such a position that the morning or afternoon sun casts a shadow on the shore? If so, use the procedure used by Egyptians to measure the height of their pyramids.

Or use a sextant from known distance away?

 

[sailaboutvic]

Just knew I shouldn't had posted .
Oh well let find on old sexton.

There’s a good video of a boat being leaned over to go under a bridge using weighted water bags but I cannot remember where I saw it -maybe others know.
