  1. Boating yesterday and today proved that the tiller is more responsive now, but has gone through neutral and on into twitchy. I spoke to the guy who added the plate and he hadn't even measured it, he heard what my wife told him about 20% of total chord, then ignored that and just eyeballed it 'because he's experienced'. Then charged us £75 for it. Aaaaaaaaarrgh
  2. Yes, I think the our fabricator either forgot what he was told, or thought he knew better. We wont be doing high speed, or tight turns on the english canals, but I like the idea of maybe balancing it up by adding to the trailling edge. Our boat was originally built as a hire boat, so I can inagine that it was designed to under perform and reduce the twitchiness of amateurs on the tiller. Sadly our plan is to sell her after next summer's cruising, as we are having a career break and going off to Europe in a camper truck to climb mountains for a couple of years, so I won't get to continue refining things, but if I can deal with a couple of improvements in advance of that I will. I like the idea ofthe fishtail rudder! thanks for all the suggestions, Jas p.s. just re-read what I wrote, so before I get flamed by everyone reminding me that a: there are tight turns and b: maneuvrability is important - what I meant was a: usually and b:I've done my time dodging gravel barges on the Trent, and better plan ahead now!
  3. Hmmmm thanks - slightly high tech for me .... I passed on the 20% in front and 80% behind the rudder stock to the fabricator who enthusiastically agreed, stuck 25% in front of the rudder stock, and put her back in the water. Bugger. So the plan is to see how that goes, if necessary I can always grind it off the next time we are near a crane out point.
  4. BillyBobBooth - yes that's what I guesstimate, butt there is already about an inch and a half, so adding another inch and a half may not make much difference. Good point about overbalance, you lose feel on the rudder and also block it when turning hard, but we already have a heavy rudder , so I'm tempted to try a little balancing. They have to get the welder out anyway.....
  5. 15% 0f 16" is 2.4, or just under 2 1/2" - I'm fairly sure we have a lot more than that. (photo below) As a rough guide though, the amount ahead of the stock in this photo is about 1/5 the amount behind, or 16.6% of the total chord. Upping that to 20% would be to increase the amount in front of the stock by only a very small amount. Probably not worth bothering with, but I will phone the dock in the morning to find out what they think. OK... this is on my boat....oh - apparently I'm not allowed to use this image extension in this community...jpg not allowed.?
  6. Just a thought - has anyone here any opinion on extending the rudder blade, by welding a section on forward of the pivot point? I beleive (from sailing boat experience) that this could better balance the blade, and reduce turbulence against the rudder causing juddering. It also moves the rudder closer to the prop, and will reduce the force needed to hold it against the force of water. But there's a good chance I'm completely wrong. Any thoughts anyone?
  7. Update from the dry dock today - 16X11 prop, so pretty much what it should be for the engine. There's a lot of clearance between prop and rudder, which may account for the steering judder, but regulation 'just over 2" blade tip to underside of swim', and only avbout 1 1/2 " of propshaft exposed. all in all leave as is I reckon....if only we hadn't found damage around the weedhatch and wear plates to the underside of swim, with a rebuild cost of £1200, I might actually be happy. Got any room in the miserable corner of your field, Eeyore?
  8. So I had a fumble about down below, and got a tape measure reading of 8 inches.....shaft to tip, which makes the whole thing 16 inches in diameter - so far so good - can't really tell the pitch through the hatch, so will have a look at it when they whip it out at Nantwich. Spoke like a local :-)
  9. That all fits, as I said originally, I'm only checking, not panicking. I need to get a Rev counter on to make sure the engine is within range, and the rest I'm going on feel from other boats I've had. Thanks for the confirmation though.
  10. well, that would be a part of the setup - as its a diesel engine I would need to use the Alternator field output and adjust for the right ratios I imagine. I'm opento other suggestions, like the tinytach, but I dont have any experience using those.
  11. Any suggestions as to a good aftermarket rev counter setup for a Kubota D1703?
  12. We're just about to dry dock for blacking and I was thinking of checking the prop. The Vicprop calculator suggests a 3 bladed 16.5" X 19.4" prop for our 54' , 17 tonne black Prince with a Kubota d1703 assuming 20 HP. It feels like it's under we have 'high' revs when cruising, but as we haven't got a rev counter it's difficult to say. I'll definitely be looking to see what the prop size is when we haul her out (I could measure through the weed hatch, but then I would, be doing that by feel, with some loss of accuracy). Anyone else have any thoughts about this combination, or experience of D1703' in Black Princes? (1991, one of the dropped gunwale/big window models)
  13. Apologies - the Kennet and Avon course at Semington dock has been re-scheduled to 25th October due to a clash with another trianing weekend. Sorry about that if you were plannign to come along, but please get in touch if you are interested in this course, cheers, Jason
  14. There are 6 places still available on the boater's first aid course at Stoke Bruerne Museum Sat. 15th Sept - 09:00 to 16:00 £50 pp. Please email me if you want further details, or have a look at the website www.northern-lights-training.co.uk cheers, Jason
  15. Hi Tim, well it wouldn't do for everyone to be the same I can't tempt you in to the one day course then.... I suppose if I just had to sit through it every three years I'd get bored - I got out of that by getting paid to teach it! cheers, Jas
