I once went under the Zeelandbruge when the electronic indicator was showing 15.6 m clearance. Mr air draft is 14.5m. I would never do it again - it was beyond scary.

Ditto, except I had miscalculated air height and VHF aerial was bent to about 70 degrees as we “rattled” under! Just a feeling of relief that we had not wiped out the masthead gear or worse. Could have been a very dangerous mistake.

When the bridge is being built I expect the clearance will be less than 18metres and certainly wont open, so that will be 6 months or so to build the central section when the clearance will be a fair bit lower. What are the chances this will be in the winter?

Why aren't they using the norm of HAT?

Makes it seem more accessible?

Makes it seem more accessible?

And it will save them a £ortune.

According to this document -> https://www.suffolk.gov.uk/assets/R...g/B-2-2-Ipswich-yacht-mast-height-memo-v0.pdf
They are using 4.0m as MHWS.
Today's tide at Ipswich is forecast at 4.4m

According to the National Oceanagraphic Centre HAT Ipswich is 4.88m. It's based on Harwich's which is 4.51m.

I have been asked to join a focus group for the crossings. I'll report back.

If I tried that it would be the ride of the brown underpants.

Why would they build a lifting section in situ?

These chaps will struggle with the new bridge.
