Hello
Is there any reason why Breydon cannot be crossed while the tide is going out? (Not to go under the bridges, merely from the Berney Arms down to the lifting bridge without going under and back again)...
How fast is the current in this half of the Broad when the tide is receding? If the boat has enough power and stayed within the marker posts, is it safe? A twin-engined sea-going boat should have enough power to deal with this, shouldn't it or is it a real rip-tide?
I'm talking about going on the Broad and then returning south, not transiting to go anywhere; just back and forth.
The reason I ask is I need to test my engines having had work done on them, and at high-tide / receding tide it is unlikely there are any hire boats. Is this right? I need to make sure everything is mechanically ok before going to sea.
Thanks in advance.
Robin

If your boat is capable of going to see the Breydon should be a walk in the park.
So in short there is nothing to stop you going over it at low or high water or between high or low or low and high.
Sure the current can be a little - but I'd guess a about 4 knots.
I'm sure someone who has more experience of boating will be able to help more with regard to how powerful the tide can be.

Better to remain silent and be thought a fool, than to speak and remove all doubt.

You'll be fine. 4mph is about the max speed of ebb you will encounter on Breydon. The strongest/fastest ebb is the Bure around the yacht station, it is not as strong on Breydon. We've done it a few times on 'B.A' during the 'Wrong' state of tide and not had a problem other than eating diesel and 'B.A' is flat out at around 10mph on still water

Agree with comments so far.
The effect of an adverse tide on speed and consumption at planing speeds is far less than on a displacment craft.
Being pushed backwards at 4mph slows a "fast" displacment speed to half, and doubles the consumption, whereas at the typical planing speed of 25mph it only slows the boat by 16%, so has far less effect on speed or consumption.
You're also far less likely to need to slow down to pass any displacment boats.
I'd keep the sea-going anchor hanked on though, even with two engines you could get something round both props, and you wouldn't want to go under Breydon and Haven bridges backwards....

Or even forwards with that lack of headroom!
It's a semi-displacment hull so I won't be planing. I just need to work the engines hard for a while.
Thanks

Thanks chaps.
Certainly was no problem power-wise this afternoon, and Griff you're right, it does get through the diesel. The last fill-up was £700 so I won't be going against the current too often!
Breydon was actually quite busy, so we kept slowing down for other boats, but still enough of a run to start smelling quite hot.

I know the price of fuel is an issue these days but i used to regularly run against the tide mainly past the yacht station - its great for blowing cobwebs and putting everything associated under test
