Carl123 Posted May 23, 2019 Report Share Posted May 23, 2019 Hi can any one tell me I have got a lot of upward wash when I'm traveling forward I have see some narrow boats with angle steel on the rudder dose that stop the wash going to waste an pushing in to more thrust Carl Link to comment Share on other sites More sharing options...
Guest Posted May 23, 2019 Report Share Posted May 23, 2019 (edited) I could be wrong, but have always thought that the angle iron was to form a step to enable one to get out of the water if fallen in. I have no idea if it has the effect that you are looking for sorry. Edited May 23, 2019 by Guest Link to comment Share on other sites More sharing options...

matty40s Posted May 23, 2019 Report Share Posted May 23, 2019 No, putting angle on a rudder can work if you have too much over wash. It's usually with boats that have a short draught, uxterplate at water level and prop nearer the back than ideal. Link to comment Share on other sites More sharing options...
Carl123 Posted May 23, 2019 Author Report Share Posted May 23, 2019 Chears there is wash how wide would they have to be and how much under water ? Regards Carl Link to comment Share on other sites More sharing options...
Jen-in-Wellies Posted May 24, 2019 Report Share Posted May 24, 2019 (edited) Is this a steel narrowboat/widebeam, or plastic cruiser? What are you travelling on when you see it, shallow canal, or deep canal/river? How fast are you trying to go? On a shallow canal, trying to go too fast just sucks the back of the boat down, creates more wash and you don't go any faster. May even slow you down. Apologies if you know this already.

I'd forgotten that thread. Contributed a bit to it as well, especially the advice about hitting it with a big hammer! Surprising how many of life's problems that solves... So it is a Piper boat, similar to mine. Not sure if it is one of David's, or Simon's if from 2002, but the design of rudder is identical. Piper boats swim and steer pretty well, so it makes me wonder if there is something else going on, other than a rudder problem with @Carl123's boat.

Wondering if the lift on the rudder could actually lift it out of the bottom bearing cup on the skeg with the design used on Piper shells.

Jen Yes I do its a steal narrow boat I'm on about 800 rpm which I'm crawling along then go up a few rpm I start to get the wash bubbling up from the back of the boat Link to comment Share on other sites More sharing options...
PaulD Posted May 24, 2019 Report Share Posted May 24, 2019 Will check the pics this evening. It does lift the rudder a bit but mine is clamped at the top bearing housing. Link to comment Share on other sites More sharing options...

I have been told that welding flat plates on both sides of the rudder will help it so I'll try that Link to comment Share on other sites More sharing options...
Neil2 Posted May 29, 2019 Report Share Posted May 29, 2019 Just a thought, - I believe Piper boats don't have baffle plates fitted to the weed hatch cover. This may or may not be contributing to the problem, but if you are having the boat docked for mods to the rudder I would consider having a baffle plate fitted, it would at least eliminate another possible cause.

Your belief is correct - certainly of the trad stern ones where the weed hatch is under the steerer's step and access is behind the engine on top of the uxter plate. I doubt you'd get the weed hatch out with a plate added given the restricted head room. That said, I have this plate free arrangement and it causes no issues.

It was years ago when I looked at an old Piper (with a cruiser stern) someone mentioned that you will never find an original Piper with a baffled weed hatch cover. I was intrigued and actually spoke to Dot Piper about it she confirmed that they didn't fit them as they were considered unnecessary and without the baffle it does make the hatch cover a lot easier to remove. I'm not 100% about it today as I'm talking about some time ago and Piper's policy/practice may have changed. Link to comment Share on other sites More sharing options...

Whilst they still refer to narrowboats on their website, Piper appear to focus on replica Dutch barges nowadays. I doubt they've put much fresh design effort into their well-proven narrowboat shells, so I'd be surprised if they've changed - nor can I see a reason to do so in terms of the weed hatch.
