RLWP Posted May 13, 2012 Report Share Posted May 13, 2012 Really? Looks to me like it is just a welded addition to the bow, to change the shape. No a completly different bow construction. Besides, the amount of space gain seems negligeble We're talking at cross-purposes. The Eco-hull is supposed to have numerous benefits to do with reducing wash, fuel consumption, lifting rubbish from the bottom, improving your complexion, plague, piles and palsy A completely semi-circular bow is shorter than a conventional bow Richard Link to comment Share on other sites More sharing options...
Teadaemon Posted May 13, 2012 Report Share Posted May 13, 2012 There is one of those residing on the K&A around here. A funny shape that I wondered about before. ECO hull? How so? IIRC, it's somewhat more hydrodynamic than a 'normal' narrowboat, so should result in better fuel efficiency. There were other claimed advantages with regard to the effect of the hull on the canal bottom, with the assertion that this would have advantages for flora and fauna, but I don't know how much data they had to make that assertion. With regard to the OP, I'd suggest that for maximum volume in the bows, combined with ease of fabrication, it might be easier to go for a transom bow, as used in some Dutch barges (and pram dinghies, like a Mirror).

Keeping Up Posted May 13, 2012 Report Share Posted May 13, 2012 I don't think the ECO-hull worked very well in practice. Certainly I can remember catching one up on the Llangollen, who was making more wash than us; he pulled over and waved us past saying that boats had been passing him all week.

It was so successful that it was soon dropped by Alvechurch who made a big thing about its development (in conjunction with BW IIRC) and it featured in articles and their advertising as a 'good thing'.

luctor et emergo Posted May 13, 2012 Report Share Posted May 13, 2012 Ok. We have over two hundred years of development, of boats, on rivers and canals. W have a lively trade on the continetal rivers, and a reasonable amou t off work on the canals for he hirebboats. Live with it Link to comment Share on other sites More sharing options...
ditchcrawler Posted May 14, 2012 Report Share Posted May 14, 2012 the idea being to have it 48 feet long with bedroom in bow with porthole above bed with no front deck to try and maximise internal living space Do you plan to cruise or just live aboard who'll moored up?

Proper Job Posted May 14, 2012 Report Share Posted May 14, 2012 There's a 'boat' with a semi circular bow on the Edwards school moorings down in Oxford. It has a seni circle above the water line. Not sure what it is below the water line. You can never tell what way it's supposed to be going (not that I've ever seen it move) Link to comment Share on other sites More sharing options...

alias Posted May 14, 2012 Report Share Posted May 14, 2012 (edited) im not sure i have done image search on google and ended up google eyed looking at all the pics but not managed to find a pic im sure ive seen one on the canal but i think it was a wide beam just wanted to look what the proportions looked like on a narrow boat searching on computers is not my strongest talent thats if i have any talent the idea being to have it 48 feet long with bedroom in bow with porthole above bed with no front deck to try and maximise internal living space It doesn't have the cabin you describe, but Jebus which is now moored between Calcutt locks and Napton Junction perhaps has round bow you are after.

I read it as Bejesus at first glance. Perhaps that's what the owner exclaimed the first time he/she saw it. Interestingly, if you google Jebus one link you come to is Jebus.co.uk and that links to a tribute to Peter Else who designed the canoe bow boats at Fenny Marina. ETA - and then goes on to talk about "Tom Pudding". Edited May 14, 2012 by journeyperson Link to comment Share on other sites More sharing options...

ETA: That site also has images of a square bow, although that seems to lift underway to reveal a more conventional underwater shape.

By the way it has nothing at all in common with the underwater bulb seen on ocean going bulk carriers. There are some horrendous bow shapes out there, like the one pictured, can we have a competition on this, i know a real nasty one. cheers for your help is the bow similar to post number 36 if so would you send drawings if poss thanks Link to comment Share on other sites More sharing options...

Athy Posted May 15, 2012 Report Share Posted May 15, 2012 I saw one of those canoe-like narrowboats at the water point in Cropredy last year and had a chat with the owner, who identified it as a "Colecraft Canoe-bow". It was about 33 feet long and the bow shape suited that size quite well, I thought; I don't think it would look right on a much longer craft. The hull of Harvest was being built while 'Trojan' was being fitted out outside. The master boatbuilder had to reprimand a member of his staff who, in tribute to Harvest's flowing lines, had chalked "clear glass" and "green glass" over two of the portholes.
