loribear Posted October 15, 2016 Share Posted October 15, 2016 When i was looking on pintrest i found a picture of potter heigham with a very large boat going through it , but how on earth did it do it , was the water extra low do you think ? Or has the bridge sunk abit over the years , not sure what year this was . Lori 5 Quote Link to comment Share on other sites More sharing options...
Gracie Posted October 15, 2016 Share Posted October 15, 2016 My guess would be it's an old photo, that is a big old boat getting through, lucky so and so, haven't been up to Hickling in a long time, such a shame, I know some people don't think so though Nice to have you back posting, Lori Grace 1 Quote Link to comment Share on other sites More sharing options...
BroadScot Posted October 15, 2016 Share Posted October 15, 2016 Where is the Ex-Pilot when you need him ? I am sure he would have the answer for you ladies. Iain 2 Quote Link to comment Share on other sites More sharing options...
TheQ Posted October 16, 2016 Share Posted October 16, 2016 Aquafibre lowliner 38ft of air draft 6ft 9 inches, lowliner I think is the clue!! note, the highest point of the boat is forward of anything you can see in that shot, see http://www.broads.org.uk/wiki/index.php5?title=Boat_Details&BoatId=7229&BoatHistory=12103 Potter bridge average clearance 6ft 5 inches +- 9 inches with tide but I couldn't find a drawing at what width you have that clearance ( the height gauge, I believe, is not the peak centre height) 1 Quote Link to comment Share on other sites More sharing options...
ExMemberBobdog Posted October 16, 2016 Share Posted October 16, 2016 I've seen boats that size above Potter this season. I believe the height gauge is at 6 foot width, ie not at the peak of the arch. 1 Quote Link to comment Share on other sites More sharing options...
stumpy Posted October 16, 2016 Share Posted October 16, 2016 Somewhere (perhaps in another place) Strowager (I think) posted some excellent photos of the 'tight' bridges with an overlay of the crucial dimensions,linked to what was showing on the height boards. 1 Quote Link to comment Share on other sites More sharing options...
BroadScot Posted October 16, 2016 Share Posted October 16, 2016 The reason I was hoping the Ex-pilot was online, his note book will have different heights from the ones shown in brochures. Iain 1 Quote Link to comment Share on other sites More sharing options...
Seriously Posted October 16, 2016 Share Posted October 16, 2016 Having a lowliner myself I was told they were designed to fit under potter . taking Into consideration the shape of the bridge versus the boat . I have yet to have ,mine under potter . My boat was built in 92 . I wonder how much the river has risen since that date karl 1 Quote Link to comment Share on other sites More sharing options...

Broads01 Posted October 16, 2016 Share Posted October 16, 2016 The Lowliner was designed with Potter Bridge in mind in the days when an air draft of 6 foot 9 would get you through more often than it does now. I'm hiring one soon (Soprano) but I'm not expecting to get anywhere close to passing through. 1 Quote Link to comment Share on other sites More sharing options...
Mowjo Posted October 16, 2016 Share Posted October 16, 2016 Looking at the prop wash and bow wash I'd say the pilot dug a hole under the bridge! for those that think I'm mad a pilot at Potter taught me to do it back in the 80's, the idea is you go full throttle at the bridge which raise the bow, as you get to the bridge you back off the throttle and the bow drops! this dips the bow under the bridge! as you get the bow under you give it full throttle again, this drops the stern under the bridge, it's weird as you effectivly curve your way under the bridge, the first time I tried it, it was a change of underpants job but after that easy, I wouldn't have the nerve to try it now as I believe the bridge has dropped a bit since the 80's, but it's great sitting there watching the pilot do it,, 4 Quote Link to comment Share on other sites More sharing options...
TheQ Posted October 20, 2016 Share Posted October 20, 2016 Just had a wander around and came across this which explains the shapes and clearances of Potter and Wroxham bridges. so here it is, as much as I hate linking to the other place, I won't copy someones work from there to here. ( It was Strowger who did the survey) http://the-norfolk-broads.co.uk/viewmessages.cfm?Forum=22&Topic=39600 Quote Link to comment Share on other sites More sharing options...
