Andrewcook Posted June 2, 2021 Share Posted June 2, 2021 As to this Fine Hot weather we are having at this time will there be any Head Room for Boats to getting under Potter Hiegham Bridge? To Hickling Broads and other places to visit? Quote Link to comment Share on other sites More sharing options...

TeamElla Posted June 2, 2021 Share Posted June 2, 2021 You could always check this simplified reference chart (see attachment) I have been meaning to test it's accuracy since producing it months ago (using another forum members source data) Note that you need to get the latest ONLINE tide gauge reading from the Repps tide gauge to use this chart Link to online most recent actual gauge reading (and recent history) is in the attached pdf document Quote PHBridgeClearances.pdf Quote Link to comment Share on other sites More sharing options...
grendel Posted June 2, 2021 Share Posted June 2, 2021 well according to that chart there should be 6 ft 10" at low water today, woo hoo, at that level I would even try taking Water Rail through without a pilot. (we reckon she need 6 ft 1" but that needs to be checked at the bridge) Quote Link to comment Share on other sites More sharing options...
BroadAmbition Posted June 2, 2021 Share Posted June 2, 2021 Monday there was about 6ft2" early afternoon, not enough for 'B.A' Griff Quote Link to comment Share on other sites More sharing options...
BrundallNavy Posted June 2, 2021 Share Posted June 2, 2021 It seems to be getting harder to get under the bridge for weeks it is around 6-1 to 6-2 then you get a couple of days when it gets up to 6-5 to 6-6 it’s all about timing. It does seem to go lower at night than during the day but having done it once in the dark it’s something I’m keen not to repeat anytime soon.

TeamElla Posted June 2, 2021 Share Posted June 2, 2021 That lovely gauge in the pilot's office needs a webcam on it Wouldn't that be something! 1 Quote Link to comment Share on other sites More sharing options...
PAULG Posted June 3, 2021 Share Posted June 3, 2021 We arrive for a week this Saturday 5th. Was really hoping to get through on Evening light 2 but not looking good. High hopes for Wroxham and Wayford though Quote Link to comment Share on other sites More sharing options...
Chelsea14Ian Posted June 3, 2021 Share Posted June 3, 2021 Speak to the yard and the pilots office. You can do so before you arrive. They will let you know. Quote Link to comment Share on other sites More sharing options...
johnm Posted June 3, 2021 Share Posted June 3, 2021 6'6" at 1100 this morning. Low tide was about 1400 so not sure what the maximum got to. The boards are well out (showing less than available by about 4") not that I would ever trust them anyway, I just call the pilot and ask ... there was a slight delay this morning as he had to move a chair to be able to see it! 1 Quote Link to comment Share on other sites More sharing options...
grendel Posted June 4, 2021 Share Posted June 4, 2021 looking at the repps data this morning, at low tide river levels were down to 0.21m, which is off the pdf chart, so extrapolating that would mean that at low tide this morning there was over 6 foot 11" at potter heigham, currently back to 0.25m and rising, but that is still nearly 6'10" which looks hopeful for anyone wanting to head under the bridge today.

expilot Posted June 4, 2021 Share Posted June 4, 2021 Much as I admire and respect the efforts of those clever enough to devise newer (more accurate?) means by which to measure air draught at Potter bridge, the only accurate measure is the gauge in Phoenix Fleet's office. Nothing larger than a boat requiring 6' 8" clearance at Potter bridge has gone past my window upriver of Potter bridge since last October! Today, the tide is lower than it has been for weeks and may touch 6' 8" - despite anyone else's calculations or assumptions to the contrary. According to Aweigh app, today's LW at Potter bridge will be at 1506. HW was at 10.07 this morning. 1 2 Quote Link to comment Share on other sites More sharing options...
BrundallNavy Posted June 4, 2021 Share Posted June 4, 2021 6-7ft at midday today. Quote Link to comment Share on other sites More sharing options...
expilot Posted June 4, 2021 Share Posted June 4, 2021 Based on my ten years' continuous recording of each day's HW and LW, under normal conditions, the tide at Potter drops 3" in the first half hour after HW and the remaining one inch until actual LW. Conversely, immediately after LW it will rise 3" in the first half hour and a further inch during the period until actual next HW. I predict that today's LW will approach 6' 8" 1 Quote Link to comment Share on other sites More sharing options...
grendel Posted June 4, 2021 Share Posted June 4, 2021 and then of course the size and shape of the roof makes a difference too. Quote Link to comment Share on other sites More sharing options...

Always get one.Yes most sailing boats will go under. Sadly most others won't .last time I went under apart from a day boat was 15 years ago.

TheQ Posted June 4, 2021 Share Posted June 4, 2021 I've been under several times with an Elysian 27. older narrower style of boat. The more modern wider boats are part of the problems Quote Link to comment Share on other sites More sharing options...

The more modern wider boats are part of the problems Same here - up until a few years ago we always used to hire this type of boat. We would get under a couple of times each year in boats such as Grenada Girl, Moon Quest, Crown Gem and the like. It's a great shame that this style of boat has almost disappeared completely from the hire fleets - the Potter pilot never failed to take us through on a Crown Gem (even with just under 6ft showing on the gauge at the bridge), but Richardsons sold them all a couple of years back. They were 6ft 3 according to the helm panel, or 5ft 11 according to the pilot, and only 10ft 6 wide I seem to recall. We know how lucky we were to have experienced the other side of that bridge so many times - the only way we will again will be in a canoe!

grendel Posted June 4, 2021 Share Posted June 4, 2021 I have never yet been unable to get through potter heigham bridge when I wanted to, usually twice each holiday when I hired from Marthams, I have yet to take Water Rail through, as we need to ascertain what she needs to get under, we think its 6'1", but i will do a test with more clearance first and see how much there is to spare. Really its all a question of hiring the right boats, and by that I mean a marthams woodie. 2 Quote Link to comment Share on other sites More sharing options...
Turnoar Posted June 4, 2021 Share Posted June 4, 2021 I seem to think Martham had a Delight in their fleet at one time, maybe ask them next time you hire Grendel, they may well remember how it compared to their existing builds. From my recollection of a photo I seem to think it had their stamp on it so may well have been modified slightly but a potential benchmark.

Marthams canopies are different, folding down neatly Quote Link to comment Share on other sites More sharing options...

I think they(Martham) redesigned the canopy to folding? 1 Quote Link to comment Share on other sites More sharing options...

Yep the canopy was changed to the standard Martham style with folding sides and canvas top eventually, along with a redesigned rear cabin and roof. She went by the name of Five by Five from around 1984/85. (After being purchased from the yard around the same time as my folks brought their boat, Nice One). All to give improved interior space and bridge clearance, or so I was told many years ago. 😊.... I think she may have been given the name Jocelyn originally, (before this class actually came along)?
